I only opened mine to see what fell out of the compressor. :-(
But when I was using it to jump-start 2 or 3 times a day, After the car started, I left the big clamps connected for 45~60(?) seconds to recharge. Did it like that for a couple months, and the internal 17AH battery always showed full.
USB for iPods, cell phones, cameras, flashlights, PSP, GPS, AA chargers...
Some newer inverters have a USB output.
China will no longer approve a cell phone for use in China unless the charge input is USB. I expect they will keep selling us ours where no 2 are the same.
