Just got an emf-390, but do not have a compatible usb connector for the unit. Can someone please let me know the precise spec of the usb needed, so I can start looking for a suitable adapter cable.
Fortunately the battery is at 75%, so I can play for a while....
1. I have an adapter from an older tablet with the specifications: Output 5V, 1.5A Is it good to charge the battery in GQ-390? 2. If it's possible to specify the full type of battery in GQ-390 (mAh etc.) Thanks.
