We built this for travellers who just landed. No account, no Spanish required, no waiting at a counter.
Use any phone camera — Android, iOS, even your laptop. You land on a secure HTTPS page hosted by MangoVolt. No app to install.
Visa, Mastercard, Amex, Apple Pay or Google Pay. We pre-authorise the cap amount and release it the second you return the device. No deposit ever held.
A slot pops a charged powerbank, or the scooter unlocks. Return to any MangoVolt dock in Argentina or Brazil — even a different city. Receipt by email if you want one.
Powerbanks: up to 7 days before we ask you to return them. Scooters: up to 30 days. After that, the rental auto-converts to our monthly plan ($190 / $1 440) or you can return it and start a new rental.
15 minutes grace, no questions asked. After that, $4/hour for powerbanks, $24/hour for scooters — capped at the lost-device flat fee. We email + push 30 min before grace ends so you can pause or return.
Yes. Open the in-rental page (the same link you got after tapping your card) and hit Pause. Clock stops. Resume from the same dock or any other.
Most international cards work, including travel cards (Wise, Revolut, Mercado Pago). If it fails, switch to Apple Pay / Google Pay on the same page. If still stuck — WhatsApp support unlocks it manually in under a minute.
Tell us via chat or WhatsApp. We deactivate the device, charge the flat lost-device fee on the original card, and that's it. With damage protection, the fee drops 80%.
