For those that spend ample amounts of time playing Pokemon Go or another mobile game, the 'Chargemander' extra battery case is designed to help keep you playing for extended periods without pausing.
The 'Chargemander' case itself is capable of being charged in just 15-minutes flat to provide up to 300% more power for your smartphone. This could potentially translate into 33-hours of smartphone gaming and usage, depending on your device, which blows other battery packs out of the water. One of the best features of the 'Chargemander' case is that it will charge your smartphone first when plugged in and then the extra battery pack rather than having them be charged separately, as with other brands.
The 'Chargemander' extra battery case is currently available for preorder on Kickstarter where the product has already garnered over $38,000 in funding at the time of publication.
