It will also charge the battery from the original charger, and a replacement as long as the specs are the same. These chargers cannot supply a 'lot' of current because of the 97's over voltage circuitry which relies on creating a voltage drop when excess current is drawn from it.

I'm looking into battery backed data retention for it.

It has on board memory to hold the programs from 810 cards. I already have PC software available to manage programs via the USB port or via Bluetooth.

Great !
As for USB power, i use an AUKEY USB "fast" charger with no problem (it can send 2A on its normal 5V ports and has an AI port in addition).

As for the 810 cards memory, that sounds great and plenty !
Just a question, how will the 97 navigates those 810 cards ?
