Agreed.Any 5V, 500mA USB charger will work (per the TRX-1 manual). I use my GoPro charger at home and an iPhone charger at work for my 1088.
Agreed as well... I tried that with my 1088 for the first few months and went back to charging the batts externally as I do with my PRO-106.charging the batteries while they are in the scanner doesn't work all that well
