For f***'s sake, bring them back already!

Chimpy-Hoarders beware: in May you can return Chimpy powerbanks with expired deposits at the kiosk and still get CHF 3 for them.

There are the kind of people who write novels, learn a language or travel halfway around the world within a few months. And then there are those who don’t even manage to return a powerbank in that same time. We at Chimpy belong to the second category, by the way. That’s why we’re giving everyone who feels the same way the opportunity to trade in their stash of old Chimpy powerbanks for the one and only thing: our love. And of course cash, 3 CHF from the kiosk you trust. That’s how much you’ll get paid for each powerbank, if the deposit has already expired. So don’t miss out again. ONLY. THIS. MAY. And don’t forget to spread the word. We’re sure you know one or two of them.
