You can get a 20a max multimeter at harbor freight for a couple bucks, Mallet works good with portable battery packs as well !

More questions, and my $.02: My multimeter has a milliamps up to 200mA, so I might have to go get an extra analog one, plus it won't even give me mA reading on a battery. My multi…

Maybe you can regulate them down to 1.5 amps and sell em to portable users, There is a market for such too!! I'd buy one from you. Portable users need 1.5 amps. 1500ma …

All I see is Apple Certified Reconditioned RM603366R6UF9590LL/A that mean anything?

I think it is the 128MB model (my notes are in the lab after doing a google search on the part number). Will look for a serial number but I think that was with the sticker that has…
