Hi, I'm new here and I hope you can help me. Been a fan of DNA chips ever since, and every dna chip mod i've used I charge via the usb port and everything worked perfectly 'til now. I bought a new device, Finder dna250w. I've had it for about a month and everything ran smoothly until all of a sudden it won't charge my batts anymore. Whenever i plug it to my usb cable the screen turns on(indicating it detects the cable I assume?) but it doesn't charge, also i can connect to escribe, and i've mingled with it following every tutorial in the internet but still didn't fix my charging problem. Also i can still use the device smoothly it's just that it doesn't charge my batts anymore, also my batts are good because I still use them only now i charge them via the external chargers. I'm always on the go and don't have time to charge my batts externaly. Someone please help. Thanks!
