You could keep your Chimpy Powerbank but then you won’t receive your deposit back. If you didn’t pay a deposit of 15.- or 15€, weekly charges will also automatically stop once they have reached CHF 15.- or 15€.
Because Chimpy offers a powerbank rental service, our Powerbanks have been used and reused. Therefore we recommend buying a powerbank at a retail store if you want to have a new one for yourself.
