RS+ doesn't power on anymore

I had similar problems my RS+ rover receiver does not power on anymore. I charged it for several hours, even two days. Before shutting down if I connected to power source it shows 100% charging immediately I removed cable it’s go down to 50% drastically and with help of power bank I’m able to used it but now it totally shut down.

Hi Wakeel,

Could you contact us on with the Serial Number of this device?

I had done that and mr polina had asked me for serial number but since Tuesday I have not heard anything from him

Hi Bakare,
