These days we can’t live without our portable electronic devices. While features and functions have improved in leaps and bounds, battery technology has not kept up with the pace and as we all sadly know, our devices have a seemingly insatiable thirst for power!
What is a Power Bank and what can they charge?
Portable Power Banks are comprised of a special battery in a case with a circuit to control power flow. They allow you to store electrical energy (deposit it in the bank) and then later use it to charge up a mobile device (withdraw it from the bank). Power Banks have become increasingly popular as the battery life of our beloved phones, tablets and portable media players is outstripped by the amount of time we spend using them each day. By keeping a battery backup close by, you can top-up your device(s) while far from a wall outlet.
Use for basically any USB-charged devices. Cameras, GoPros, Portable speakers, GPS systems, MP3 players, smartphones and even some tablets can be charged from a Power Bank - practically anything that charges from USB at home can be charged from a Power Bank - you just have to remember to keep your Power Bank charged, too!
While there are many types of power banks on the market however, not all Power Banks are the same and there are some important points to consider before making your purchase.
LASER Power Banks use protection circuitry to prevent over charge, over discharge and over load, which can be detrimental to the battery and potentially dangerous to devices and/or yourself.
With so many power banks on the market, how do you know what to trust? Many look the same yet they will perform differently due to the circuitry, construction, grade of battery and most importantly compliance with Australian Standards. Be sure to ask about the brand / grade of battery cells, types of protection circuitry used, test reports and EMC/C-Tick certification. Most importantly, query the company or brand who holds the product liability and how reputable that company is. How long have they been in business?
01 Over charge / Voltage Protection
Allows the battery to charge to its maximum capacity and automatically stop when it is full. The inbuilt voltage regulator ensures a consistent and stable power flow to your devices.
02 Over Discharge Protection
With Lithium battery cells, it is vital that a small nominal charge remains in the battery, even when fully discharged. Built in over discharge circuitry stops the battery from running too low which can reduce battery life, performance and the ability to charge.
03 Over load /Over Current Protection
When a charging device is overloaded, it can cause power spikes which can damage equipment. With over load and over current safety triggers in place, you can be assured that your devices will remain safe regardless of the input current.
04 Over Run Protection
Ensures that the voltage which is powering up the battery are received by the battery at a constant flow.
05 Short Circuit Protection
Potential damage to the power supply or your device. Ensure your next Power Bank has inbuilt circuit breakers and comes with quality cabling and sturdy construction to ensure you and your devices / car is protected. This also protects against reverse polarity and sparks.
Pre charged – ready to go
With the power and usage demands of the latest smartphones and tablets, don’t be caught out with a flat battery. LASER Powerbanks are Pre charged and ready to use straight out of the packaging. This means you can buy the powerbank and get up and running straight away. With other powerbanks you need to charge them first. What’s the point in that?
Long Shelf life
With quality battery cells and efficient monitoring circuitry, you can expect a long shelf life with LASER Powerbanks. Up to a year or more* in fact which means you can store it away in your car’s glovebox**, your desk drawer, handbag or even with your travel docs – ready to use.
*battery life and charge retention is effected by temperature and storage conditions
Number of charges/
A common measure of Powerbank performance is the number of charges and discharges a powerbank can perform before their performance is compromised. Typically a smaller Powerbank will provide up to 500 charge / discharge cycles before becoming less efficient. That doesn’t mean that the Powerbank is useless after 500 cycles, it just means that the Powerbank is less efficient say only 50% of original capacity) after 500 cycles (which could be up to 2 years with regular use).
– LED status lights
LASER Powerbanks have LED indicators which show whether the Powerbank is charging, fully charged or out of charge. On the bigger models the remaining capacity is shown by a row of LEDs so you know how much power is left before the Powerbank needs to be recharged.
– what’s that?
With older battery cells, you used to get a memory effect. Simply put, to get the best use you had to deplete the battery and then fully charge it. With Lithium cells, this is less the case. So you can charge when you want and use as much or as little as you need before recharging again.
On Battery Life
Did you know that fluctuations in temperature can affect the shelf life and longevity of your battery? So to get the best performance from your Powerbank, try to keep it stored at room temperature.
How do I charge a Power Bank?
Most commonly, a Power Bank will have a dedicated USB input socket for charging. You can either charge your Power Bank from a computer but for a faster charge you can use any wall charger or in-car USB charger. Power Banks commonly use a Mini or Micro-USB socket for charging, and full-sized USB sockets for connecting your device. In some cases however Power Banks can use the same socket for input and output.
How many times can my power bank charge my device?
At LASER, we use an icon system to indicate how many device charges you're likely to get out of a Power Bank before it needs to be recharged. Our figures are based on a formula which assumes an average device capacity of 1500mAh, a device power level of no less than 20%, and an 80% Power Bank efficiency rating. Many Power Banks boast efficiency ratings up to and over 90%, but we find that real-world usage in Australian climates typically ends up with an 80% efficiency rate. We also like to err on the side of caution to give you a conservative estimate rather than make outrageous claims. Generally, the bigger the Power Bank and the smaller the device you're charging, the more goes you get. Other factors can also improve or limit the discharge potential of a Power Bank, so look after them and they'll work better for longer.
How fast can my Powerbanks charge?
The input rating determines how quickly your powerbank will charge. The higher the input amps, the faster your powerbank (or device) will charge. So a 1Amp input at 5volts (which is 5 watts) would not charge as fast as a device with 2Amps (10watts). It also depends on the charger. A powerbank with 2A (10W) input will not recharge any faster than a 1A(5W) if the USB charger can only output 1A(10Watts) and vice versa.
What are Watts & Amps?
To use a garden hose analogy, the width of the hose would be the voltage and the speed of the water would be the Amps or Current. Watts is a simple expression by multiplying the two numbers together. Typically the true measure of power is expressed in watts.
Devices only take what they need (current autosensing).
What's the difference between Li-Ion versus Li-Polymer?
Lithium-Ion and Lithium-Ion Polymer batteries are the most common rechargeable cell types found in Power Banks. Lithium-Ion cells are generally cheaper and limited in mAh capacity, while Lithium-Ion Polymer cells can be larger and don’t suffer from a memory effect over time.
What kind of connection cable do i need?
Make sure you Power Bank comes with the right connections for your portable devices.
Many power banks come with one connection port and if you are lucky a cable. We all have different devices that need different connecters and who is to say the next phone or other portable device we buy will have the same connecter. Look for a model that comes with a range of connecters to future proof your Power Bank.
Do you have a range of colours and styles?
Available in a range of colours and casings, Laser Powerbanks have a style to suit your needs.
What does mAh mean?
Batteries common to mobile devices and Power Banks are rated on their ampere-hours, measured in milliamps to create non-decimal numbers. The mAh ratings denote capacity for power flow over time.
