What are Portable Power Banks And How Do They Work?
Many portable power banks are actually integrated into the device case. Most will double or even triple your battery life. Many are even solar powered, meaning, that’s right, as long as the sun’s still in the sky you’ll basically always have power.
There are basically 3 types of portable charger—charger cases, USB plug-in charging banks, and solar chargers.
Portable Charging Cases
Now this is genius. A portable charging case is basically a protective case, which you need anyway, that actually charges your device automatically. When you’re at home you just dock your device to your computer or wall plug as usual, only with a charging case you’re actually adding up to 10,000mAH of reserve power so that when your battery dies you have 2-3 times more power on reserve. Cellz carries these iPhone 4 accessories for instance that double as cases, add very little bulk or weight, and look cool at the same time. Wherever you go you’ll have backup power that connects directly to your device’s input and kicks in automatically when your battery runs out.
USB Plug-in Power Banks
These are pocket sized little units that connect via USB to your device and will repower your battery when there’s no electricity outlet in sight. It’s basically just a secondary portable battery. This is something that you’ll never travel without so that next time you’re looking at the 10% battery warning you’ll just slide it out of your pocket and wham, you’re back to full power. An example are these portable power banks. When near a power source you plug it in to power up, then when you’re out and about you’re carrying a secondary battery. Problem solved.
This is super cool, particularly if you’re going camping, hiking, working outside, or just on a trip. You can use it for any USB device, so yes, for your tablet, phone, or laptop even, and it’s the size of a smart phone. Basically one side of the device is a solar panel that uses the sun’s rays to collect and store a reserve power source. It’s constantly renewing so long as it’s in the sun so you can for instance place it on the dash of the car when you’re heading somewhere then slide it in your bag when you set off and you’re carrying a dependable back up source of power.
So, next time you’re watching your phone power off at the worst possible moment, think back to this moment when you learned about this awesome solution and think, did you grab it when you had the chance?
