This will be the most compact standby charger for mobile devices

This year we continue to see the rapid development of technology on smartphones, from faster processors, more RAM, larger screens with higher resolutions. All is just to serve the needs of the user's experience better. However, the battery is still a problem that any phone will encounter.

The majority of users are still unhappy with the battery life of their smartphone, and they still have to carry their charger or battery back up all the time. But each has its own shortcomings, the rechargeable cup can not be used on the move or in an area with no electrical outlet. With the traditional backup charger, it's too bulky and bulky.

Traditional backup batteries are too bulky and cables are too entangled.

There has been a solution to use a case with integrated battery backup, but this is also not good because the size of the phone is so much upset that users are quite uncomfortable in the operation. To address the battery problem, the New York-based POPTech team has come up with a very cool idea: a super-compact backup charger can "stick" on the back of the phone.

The size of this POP backup battery is extremely compact, 8.1mm thin and weighs just 15g (when not attached). Inside the POP is a 1.800mAh Samsung S2 battery, a feature that removes the battery and replaces another battery to continue charging. In addition, the charger's cable POP is quite short, just enough to connect to the microUSB port on Android or Lightning on the iPhone so it will not mess and entangle it when used.

The price for a backup charger is quite reasonable, only $ 15 for the "shell" and if you buy combo shell with the battery will cost $ 22. This project is being raised on Indiegogo's website and the first products are expected to be delivered to the public in September 2016.
