## Questions & Answers

**Q: can it be used with an inverter**
A: Not recommended. Suggest you choose a right voltage/ country. I bought one from US and didn’t work. Finally bought another one from UK.

**Q: Can this be used as a 12v battery support for when remapping the ECU?**
A: I would say no, as the output current supplied by the charger is automatic, so if the battery is full or close to full it won't provide a high current only trickle, but it will keep a current flowing somif that all you need it.might work for a remap..worth checking some remapping forums rather than Amazon...

Easy to use connect easy, function really well, easy compactness ,safe to use ,charges well

### ⭐⭐⭐⭐⭐ Awesome piece of kit, but a bit pricey
*by A***R on 14 May 2024*

Does the job perfectly, would like a bit more of a display to tell me what its doing. Also for the money I'd expect to be able to replace order new cables without having to return the whole unit, would make it easier to store and transport too.
