Very good ### 5/5 — Super *2025-01-05* Charge rapide vraiment très ingénieux d’avoir l’os en moins place ceci ### 1/5 — This app DOES NOT WORK *2025-01-01* The app didn’t work at all. It asked for my phone number and then didn’t send me the code that I needed to unlock the power bank. It took away 96% of my remaining battery life. My friends also tired the app with the same result.dont waste your storage space with this app! ### 1/5 — This app low-key doesn’t work *2025-01-01* Maybe it’s cause I was at the goofy Marseille airport, but the app would ask for my number and then just not send the code I needed to unlock the battery pack. Two of my friends tried it as well and had no luck. It wasted more battery than it gave. The logo is kinda cool though 🔥🔥🔥 ### 5/5 — Batterie externe *2024-12-18* Trop bien sa charge bien ## Most critical reviews (10 lowest-rated) ### 1/5 — Do NOT use! Scam *2026-06-18* I used this in Amsterdam airport, returned within 10 minutes to the exact spot and they claim they will not return the deposit despite providing evidence. ### 1/5 — Glitchy *2026-04-03, version 140.2.0* The app is often glitchy and unresponsive when trying to access or return power banks. This has resulted in bank chrges being incurred and deposits not being refunded. Avoid. ### 1/5 — DO NOT USE: Absolutely garbage service *2025-10-14* This is a horrible service and I would not use again. It’s a scam operation dressed as a business. They were rude to me in customer service and basically told me I’m not so many word that I should go fuhhh myself. Their chargers are either unavailable or they don’t work. Yeah. Do not use horrible service and will be filing complaint against them. ### 1/5 — No country change *2025-08-05* The app doesn’t allow you to change the country for your phone number so there is no way to use it. ### 1/5 — Doesn’t send SMS *2025-07-24, version 138.3.0* Can’t create an account as no SMS is received. Can’t get far enough on the app or website to rent a battery. ### 1/5 — Can’t sign up *2025-07-23, version 138.3.0* I can’t sign up with UK number ### 1/5 — Will not work *2025-07-17* This app will not allow for me to change the country to enter my phone and sign up. My phone was nearly about to die and I needed help and this is a failure of a system. ### 1/5 — Bug regarding code confirmation *2025-07-15, version 138.3.0* No confirmation code sent to number no matter how many times I tried meaning the service was completely unusable. ### 1/5 — Activation code *2025-07-09, version 138.2.0* Tried to use the app but the activation code was not coming through via sms. An email log in option would be better ### 1/5 — Inoperable *2025-05-28* Cycled through half a dozen times. Never received a code, so can’t judge the experience beyond that. ## Most praised reviews (10 highest-rated) ### 5/5 — Aucun soucis pour l’instant *2025-09-10* Les 3 jours de dépôt est un très bon atout.
