How to choose a battery powerbank

Laser helping travellers keep powerbank in carry-ons

Stay Charged when you travel

What makes our Car Jump Starter Powerbank different? Well it boils down to quality components, safety and features


Within built circuitry for  over-current, short-circuit, overload, over-voltage, over-charging and reverse polarity you can be assured that you, your equipment and your car's sensitive electronics are protected. Furthermore all Laser powerbanks are certified safe to use and are compliant with Australian electrical safety guidelines.

 Our powerbanks are precharged which means out of the box they are ready to go. 


Long Life

Using high quality Lithium cells with maximum efficiency, our Powerbanks hold charge longer and typically return more than 75% charge after 6 months.(*dependent on storage conditions)


??The charging tips and chargers are included
Yes, in the (hard case) box, we include popular 9 pin (for newer Apple devices); 30 pin (for older Apple Devices) and Micro and Mini USB (for most other devices). Simply connect the multi plug cable into the PB-CJ12000 and charge away. For car starting, we include heavy duty car alligator clips (Red and Black colour coded) which has built in safety circuitry in the cable. In the pack we also include a 240v Home wall charger and a 12vDC car cigarette socket charger (note - to fully charge the power bank, you will need more than 7 hours using the wall charger - hey, it's 12000mAh - that's a lot!)

High Power output gets your devices charged FASTER

With 2.1Amps (10.5 watts) of power output from the USB port, your devices (especially tablets and larger smartphones) will charge faster


Start your engines

With 400CCA'S (Cold Cranking Amps), you can start most engines (such as 4, 6 and some 8 cylinders as well as many diesel engines). This includes cars, boats and motorcycles(12v). In fact, you don’t even need the dead / dying battery connected. The PB-CJ12000 will start a car without the car's battery *(just on the power bank alone).. NOTE: the power output for vehicle starting is 12v DC. It will not work on 6v systems (like some motorbikes, watercraft and machinery)

Up to 20 car Jump starts and 7 smartphone charges
With 12,000 mAH of capacity,in independent testing, we've started 20 cars* with no car battery connected. So imagine the benefits here, it will not only get you back on the road, but you could re-start your car if you had to pull over or stop (like to get petrol). *(the test was conducted on typically newer 4 cylinder cars) older cars and/or big engines may not offer the same number of charges due to the current required to turn the starter motor. Some later model V8/V10 luxury vehicles with a lot of electrical ancillaries may require a different jump start cable/plug)120000 mAh also gets your smartphone charged about 7 times and your new tablet charged fully with some left over. 


Powerful LED flashlight and emergency strobe light
With 86 lumens of lighting power the small yet powerful LED light can help you see at night and is a handy all round torch. You can get up to 120hours of torch only use making it great for camping.For attracting attention the LED light becomes a strobe (flashing) light as well.


LED charge status lights

Check the remaining capacity or charging status with the LED status lights.


The PB-CJ12000 weighs less than 400 grams (so you can easily put it in your backpack, case, handbag (if you have a big one) and desk drawer. It also comes with a handy hard case if you want to store it away or take the complete kit (say if you go camping).

So how does such a small powerbank get something like a car started?

Without getting too technical it's all about the CCA power and how it's converted into 12v charging current. Older type batteries (like nicad and nical metal hydride) are bigger, heavier and much less efficient. That's why Lithium is used in virtually everything from phones, tablets, GPS, cameras and even the latest electric cars like the Tesla. So using the latest in Lithium battery technology, some smart circuitry and safety cutoffs, you can effectively jump start most cars (or boats/ motorbikes) with this powerbank.



What are the variables in output power?

There are many variables in determining how the Car Starter Powerbank performs. The biggest is the way it's stored (temperature variations reduce the battery holding capacity and reduces it's efficiency). Also, for late model cars with lots of electronics and convenience features - the current drain is quite large so it would be best to turn off ancillaries like air con/radio/lights/heated seats and so on to get the best performance when jump starting your car from the powerbank. Typically a larger car with many convenience features (such as a European luxury car (V6/V8/V10)) may get less than 10 starts due to the amount of current required just to run the ancillaries. 


How Power Output is delivered

The three most common values used when discussing electricity are; 1) Voltage or “V” (measured in volts), 2) Resistance or “r” (measured in Ohms) and 3) Current or “I” (measured in Amps)
When applying these terms to Consumer Electronics, we most commonly hear about them being applied around products like USB charging devices. 

In this application most of us know USB runs on about 5.0 volts. Resistance, well, resistance is very rarely used and of little interest however when compared to current.
Current is very important as it describes the strength of the voltage or how fast it flows.

If you consider your garden hose as an analogy - voltage would be the width of the hose, the current would be how fast the water flows through it.
Eg. You can fill up a bucket of water faster when you turn the tap on faster. 

When talking about wall plug USB chargers, built-in circuitry converts the 240 volts mains power down to 5 volts (for USB) and in varying currents or amps. Car chargers also do the same this, however they convert 12 volts down to 5 volts also with varying strengths. Early chargers only had fairly modest outputs of about 1.0 amp, however modern chargers can now output up to 2.4 amp which effectively can charge a device in almost half the time. 

This 5 volt USB power can also be used not only charge your smart phone or tablet, but it can also be used to charge portable power storage devices called power banks. These power banks can also deliver varying amounts of current or amps however it is measured in a slightly different way, called Milliamp Hour or mAH for short. Eg if your smart phone has a 5,000mAh battery, you can get up to two full charges from a power bank that can hold up to 10,000mAh of power.

Did you know?

We use batteries to charge most of our portable electronic devices (PEDs), but they can have serious safety consequences if they're not carried correctly when you're flying. For example, in 2014 in Melbourne, undeclared lithium batteries were packed into a passenger’s checked bag and short-circuited, igniting a fire in the aircraft’s cargo hold before passengers boarded the flight to Fiji. Since then, there has been various types of safety materials produced, that help passangers make sure their luggage is safe, even including Can I pack that? dangerous goods app and an easy to follow safety video, seen below.

How to carry batteries safely

Watch the CASA safety video - Travelling safely with lithium batteries.



Batteries under 100Wh rating

  • The batteries that power your phone, laptop and camera are usually under the 100 watt-hour (Wh) rating.
  • If you're carrying a spare battery that's not in one of these devices, it must be in your carry-on baggage only.
  • Spare batteries, regardless of their size are not to be carried in checked luggage.

Lithium Ion batteries 100-160Wh rating

  • These are more powerful batteries, and can be found in industrial equipment such as power tools and mobility aids between 100 and 160Wh.
  • You must have approval from your airline before flying.
  • If the battery is installed in a device, it can be carried in either checked or carry-on baggage.
  • If the battery is a spare - that is, the battery is by itself and not contained in equipment - it must be in your carry-on baggage only.
  • Spare batteries, regardless of their size are not to be carried in checked luggage.
  • There is a limit of two spare batteries per person. These batteries must only be packed in carry-on luggage and should have their terminals individually protected to minimise the risk of contact other metal objects in your luggage.

How to protect your battery from short circuits

Short-circuiting batteries have been responsible for numerous on-board fires, so it’s important that all spare batteries have their terminals protected properly.

You can do this by:

  • Keeping batteries in original retail packaging or
  • Insulating the battery terminals by taping over exposed terminals or
  • Placing each battery in a separate plastic bag or protective pouch.

We also demonstrate these techniques in our safety video above.

Lithium Ion batteries 160Wh rating and above

  • You can't carry lithium batteries above 160Wh unless they are for wheelchairs and other mobility aids.
  • These batteries must be transported as declared dangerous goods cargo.

Please contact your airline for guidance.

What’s your watt-hour rating (Wh)?

  • Most modern batteries have the watt-hour rating (Wh) displayed on their casing so you can see how powerful they are.
  • Some older models might not have their watt-hour rating clearly displayed but you should be able to see the voltage and amp hour which will make calculating the watt-hour simple.
  • To calculate your battery’s watt-hour rating, you multiply the voltage (V) by the amp hour (Ah).
  • For example, a 12 volt battery with a 5 amp hour rating will be 60 watt-hours. V x Ah = Wh.
  • If the battery is rated in milli-amp hours (mAh), divide your final answer by 1000 to arrive at the watt-hours. V x mAh / 1000 = Wh. For example, a 6 volt; 2500 mah battery will be 6 x 2500/1000 = 15 Wh.

Buying batteries online? If it sounds too good to be true, it probably is

A lot of counterfeit goods are sold online and with batteries powering most of our personal devices, there's a high demand for spare, replacement and second-hand batteries. Unfortunately, electronic counterfeit goods do not meet stringent safety standards and pose serious dangers to the end user.

The best way to make sure the battery you’re buying is genuine is to buy it from a reputable, well-known buyer. If you're going to purchase a battery from a lesser-known distributor via the Internet, always keep the following in mind:

  • Price - if it’s too good to be true, it probably is.
  • Make sure the shrink-wrap on the exterior is tight and professional. Auction sites offering products with no box or manual, no warranty or documentation, are usually counterfeit.
  • Any cheap, faded, damaged packaging, labelling, strange markings or misspelled words are also signs of counterfeit products.
  • Ask the seller if you’re buying a genuine product.
  • If you’re still in doubt - don’t buy it.

Example 1 - Spot the difference

Counterfeit and genuine batteries shown side by side

Can you spot the fake? Counterfeits are becoming so convincing that the only indicator may be the price. In this case, the battery on the left is genuine article, with the one on the right produced by a counterfeiter.

Looking after your batteries

Damaged batteries can be dangerous. Whether they’re dropped, smashed, overheated or mistreated in other ways, lithium batteries can become unstable and have been known to ignite fires due to mistreatment.

Batteries show clear signs of being unhealthy. Such signs include:

  • Bulging
  • Discolouration
  • Squashed/deformed
  • Spilt case
  • Leaking fluid.

If your battery shows any of these signs, it should be replaced. It’s also a good idea not to travel with your batteries fully charged. Keeping charge levels at 40-70% will keep the particles that store energy in their most stable state during travel, minimising the risk of thermal runaway.

Batteries don't last forever and it’s important to monitor them. Continual dischargers, over-charges and quick-charges will eventually reduce the battery’s overall capacity and health.

Safety is the first thing that jumps to mind when buying a Power Bank. The main component of a power bank is a lithium ion / lithium polymer battery and by nature they can be a little temperamental. Although they are one of the most commonly used types of battery today, safety is still treated very seriously. There are two parts of a power bank that are of specific interest, these are:

1. Battery Cell quality

A “Grade A” battery cell is a common industry term used to describe a quality battery made from premium materials and made using leading manufacturing processes. The real measure however of a battery’s quality is, whether it has undergone and passed UL Certification. Even though power banks can be tested to many different certifications, the most comprehensive is the UL Certification test called UL1642. UL1642 is a set of rigorous Electrical, Mechanical, Environmental, Fire and Heat Exposure tests. UL is the most widely accepted certification that ensures a battery’s compliance with world leading and globally recognised safety standards.

2. Protective Circuitry

The Protective Circuitry or PTC (Positive Temperature Coefficient [circuit]) is considered a “Safety Valve” that protects equipment against excessive current from external short circuits, abnormal charge/over charge, forced discharge and other dangerous conditions by directly reacting to rapid increases in current by physically impeding the energy flow, then returning to a normal state once the excessive current has passed.

It’s easy to reduce the costs of power banks by cutting out the cost of battery certifications and protective circuitry, but by doing so creates a real risk to the safety of the power bank, any connected devices and even the end user.


How do I choose the right type of Power Bank for my customer?

The first step is to know what your customer’s expectations are. In general, power banks can be categorised into three main types based on capacity and usage. Single charge batteries, multiple charge batteries and specialty power banks that can jump start cars and power notebooks and laptops.

1. Single Charge:

This category of power bank provides the lowest capacity and price.

2200 mAH is the most common capacity adopted by the market.

Single charge power banks are ideal as an emergency backup for charging phones. These smaller capacity power bank batteries however do not have enough capacity to fully to charge an iPad, tablet, or other devices which have higher capacity batteries. (they may give you only 10%-20% for an iPad Air 2 for example)

Phone batteries vary greatly in capacity so it is important that you understand the battery capacity of your device and the capacity of the power bank you intend to purchase. Smaller capacity power banks (<2000mAh) (when compared to a device battery capacity like an iPhone 6) may not provide a full charge for a device as it depends on many factors such as age of the phone, power bank, level of charge and so on.

2. Multiple Charge

Multiple charge Power Banks cost more than single charge Power Banks as they can charge multiple devices or multiple devices at once, with significantly larger battery capacities.

The Capacity ranges from 3,000 mAH to more than 10,000 mAH.

Power banks in this class are able to charge phones and tablets, many of them equipped with two ports, one for charging phone and other for Pad or Tablet.

3. Specialty Class:

Special Class Power Banks can charge multiple phones and tablets and also laptops and notebooks and some can even start up your car when the battery has gone flat.

Special Class Power Banks have very high capacities and models can be tailored for specific uses.

Special Class Power Banks cost more compared to Single and Multiple charge power banks.


How long will it take to charge my phone or iPad?

Charge time depends on the battery capacity of your device. In general, the larger the battery the longer it will take to charge. It is a common misconception that a larger capacity power bank can charge a device quicker, this is not the case. No matter the capacity, all power banks will deliver the same amount of energy to a device over a same period of time. So, if you have two phones that are exactly the same and one is being charged by a 2200mAh power bank and the other by a 6600mAh power bank, both will receive the same amount of charge at the end of one hour. The only difference is that the 2200mAh will have less charge left over than the 6600mAh power bank.

How long will it take to charge the Power Bank itself?

The same principal applies with charging a device – the larger the power bank battery the longer the charge time, however, a 2200mAh power bank may take only 2?3 hours to charge, whereas a 6600mAh power bank may take up to 3.5 hours to charge. Using a wall charger will give you the best results because it outputs a higher capacity charge than a PC (USB socket). A PC socket can typically delivery 500mAH of power whereas a wall charger can commonly provide up to 2400mAH of power (Note: As mentioned before, safety circuitry can restrict the flow of current to a device if excessive, so usually anything over 2400mAH will not see any improvements in charge time)

How many times can a power bank be cycled (recharged)?

Depending on the age, condition and class, a power bank may be cycled up to 300 to 500 times. Over time however, the capacity will slowly decrease and eventually need replacing, much the same as you see with a typical smartphone or tablet. A power bank when not in use or put into storage for extended periods should at least have an initial charge of about 50%. Storing a power bank without any charge will dramatically reduce the overall life expectancy of any battery.

What kind of cable comes with the power bank?

Most power banks come with a simple USB cable that is only used to charge the power bank itself. Some LASER products however come with charging cables that will suit multiple devices such as old and new Apple devices and devices using micro and mini USB connections.

Why is there different input and output sockets?

The input, which is usually a Micro USB connector socket, is used to charge the power bank. The output socket is most commonly a normal size USB socket. Simply plug your device’s charging cable (USB side) into the power bank to begin charging your phone or mobile device.

How many phones will a Power Bank be able to charge?

As the above name roughly suggests that a single charge power bank may charge up one device and a multiple charge power bank can charge up to 2 or 3 devices. The best way to calculate this is to match the capacity of your device with an equally or larger size capacity power bank. In this way, you are all but guaranteed one full charge from your power bank. 


Does a power bank work with both iPhone and Android phones?

Yes. Essentially a power bank is just a battery which is connected to a USB socket. There is no software or hardware to cause any system compatibility issues. As mentioned previously though, you do need to be aware that matching your device with the correct capacity power bank is very important.  

Do you carry a charging cable that can be used with my phone?

Most phones and tablets come with their own USB charging cable. LASER however does include charging cables which suit multiple devices (such as 30 pin, 9 pin and micro USB).


One simple but important reminder

To prolong the battery life, always keep it fully charged where possible. It is also a good habit to get into, and charge any new battery overnight.

How do I prolong the life of my power bank?

Avoid storing power banks in extremely hot or cold environments. Always store your power bank with at least a 50% charge and avoid storing your power bank is it has been completely drained. Keep your power bank out of reach from children and be careful not to drop, break or otherwise attempt to disassemble it. Internal components can be harmful if tampered with incorrectly.

Charging your Power Bank in your car

Avoid connecting a power bank to a car charger until the car has been started. Many car chargers on the market may not be able to safely handle the sudden peak of current during vehicle ignition and may damage the power bank.

What does Power Bank Capacity mean?

Power Bank capacity refers to how much charge can be stored in a power bank battery. It is measured in mAH or milliamps per hour. It is also important to note that when a power bank is charging a device, some of the energy is lost in the transfer. In simple terms, it takes energy to transfer energy. So, the real capacity of a power bank maybe off by a factor of 10 or 20%.

Does a High Capacity Power Bank charge a phone faster than a Low Capacity Power Bank?

No. The charge speed is determined by output current, not the capacity. (An even more accurate answer actually would be what the safety charging circuitry of a device limits the charging current to)
