Here is what i just discovered also...
Was at a friends house overnight for a bday party and normally i put my phone in the cradle at home but didn't grab a cord to bring with since i generally use car charger if away from home... Well we tried every micro usb charger in the house, none worked except for one. The only difference? The ones that wouldnt work were rated for 500mA and the one that worked was rated for 700mA.
My stock Casio charger shows 700mA i believe, will have to dig out from behind nightstand. An LG model charger that i have from my previous phone works fine which is 700mA and the micro usb from another phone that i have which is 500mA also doesn't work like all the others it tried the other day.
So i would appear the Commando is power hungry. I have a 1 amp rated car charger cord that charges every phone i have ever tried it on, it was an expensive Motorola model but its filtered and fused and well worth the investment as most car chargers i have used before cause RF noise to my radio equipment.
Was thinking.... Just tried another charger, the one for the Kindle we have, its a 500mA unit also. When i plug in any of these 500mA units it says USB MODE or something like that on the screen, it varies, but never says charging or not charging.
