Does it walk the walk...
The battery in the wallet could easily have been bigger to make more use of the product, especially if you are an android owner. The wallet takes quite a long time to charge, about 2-3 hours. On my Galaxy S6 it will charge it to about 30-40% so don´t expect to charge your phone many times on one charge.
Just a warning, people around you may ask questions about why the hell you need to charge you wallet, just tell them it is to refill your bank account.
