2.4A Car Charger with 3 in 1 Charging Cable BLACK
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.
The Laser USB 12v car charger, charges your device at full speed whilst you’re on the road so you can get back up and running.
With 3 in 1 cable ( lighting - for new Apple devices, 30 pin - for old Apple devices, Micro USB - for Android devices) you can charge 99% smart phones or tablets, no more messy / tangled cables around.
