9.7 ereader with SD card any for sale?
Hey I noticed there were quite a few older onyx boox ereader's with 9.7 inch screens that had an sd card. I was wondering if anyone is selling their older device. Preferably with USB C but if it is micro usb I am still interested

I am so looking to find a device that works. I had 3 new devices but they all have issues with the battery. I never had any issues with my kindle devices.

Really? Were they Onyx? All the same? Did you consider replacing the batteries?

Yeah they were all inkpad lite's brand new. I still have this one in the return period but it's already turned off randomly as well just said low battery 5 percent so I'm not sure what is going on.

A bad battery will discharge faster than it should, but almost any battey should be able to charge to full voltage. Maybe the problem is your charger? You need to look at voltage with some utility. For Android, you can use my UsbMode.apk in my sig.

It charges to 100 percent but then would just randomly jump from 40 to 5 percent battery in a matter of seconds.

I am using the apple wall charger for my mac and a usb c to usb c cable should I use the one that came with pocketbook? I don't really use usb cables anymore though

Battery SOC (state of charge) calibration can be off.
If you keep the battery above "40%" does it work reasonably?

Yeah my old unit lasted about a week and it was fine until it hit 40 percent but this new one lasted 3 days but I thought the battery was supposed to be longer
