If you like the small and very capable ISDT Q6 chargers, you will definitely like the B6 NANO charger from SKYRC!
The form factor is similarly small, the max charge current is higher, it has 3 discreet touch-sensitive buttons and a clear and simple screen layout.
Paired with a mobile device via bluetooth and using their app, you can control the charger from your phone or tablet, create charging / discharging presets and also print out QR Codes for the Scan-to-Go feature!
You can also monitor the charging progress from a distance, through the device, but you are of course not advised to charge unattended by any means 😉
This is BEST FOR LESS: SkyRC B6 Nano battery charger: Scan-to-Go with mobile APP for easy charging – Let’s go!
