Yes it does charge. I plugged a charger into it and it works great. I cannot send the charger because I only have one of that kind. I need it for other devices.
It doesn't have wifi to where you can go online with it. It had wifi to search for books and magazines. The screen appears to be 6 inches. I am charging it right now to see if I can find out the GB.
I looked up the model number BNRV300. This is the specs I could find: 6" (800x600) Touchscreen Display/ Up To 2 Months Battery Life/ Adjustable Text With 7 Font Sizes And 6 Font Styles/ Built-In Wi-Fi (802.11b/g/n)/ 16-Level Gray Scale For Greater Detail/ 2GB Internal Memory Holds Up To 1,000 Books (1GB For Content; 750MB Reserved For B&N Content) (Expandable microSD Card Up To 32GB Sold Separately)/ Black Finish
