THE CREDIT CARD 850MAH
The Credit Card 850mAh powerbank measures 92mm in length, 62mm in width and is only 4.9mm thick (like 4 cards) and weighs just 41g.
To get a better idea on just how thick this powerbank is we placed right next to the HyperX flash drive by Kingston.
Right next to the microUSB charging port we see a blue LED and a small rubber button. The button is used both to turn on the battery state LED and to begin charging of the device you want to recharge.
At the rear we see the microUSB charging connector and information about the device such as capacity, output, country of manufacture and certifications.
To release the microUSB charging cable you just need to push the connector from the front.
As you can see the microUSB charging cable is not long but it gets the job done.
After trying to store the card in the card spots of three different wallets i came to the conclusion that it can only be stored in the pockets right behind them (it's 1.5mm longer than it should but since you may have a larger wallet this is just an observation).
