LOL! Yeah, I have one too and it's thin, light, and works beautifully. Imagine that...something made for a specific purpose, and used for that purpose as intended, likewise resulting in expected performance. What a concept!

Thank you, FoxKat! I charged to 100% w/ power off, drained to 15%, and back to 100% again last night w/ power off. Today will be my 2nd cycle. I'm going to keep using the G'Nex charger unless I'm told otherwise. Appreciate the link to batteryuniversity. Wow. I've never given much thought to chargers until now. I have been reading various Android forums for almost a year, and I have never read a thread about the importance of using the right charger/ins & outs of the battery process. Great info & help
Motorola P893 portable power pack, its a little USB/micro portable charger/external battery. About the size of a D1, about as thick as a bionic, active charger circuitry, integrated 3 1/2" micro cable. You can either use it to charge your phone from almost dead (which I call 10% and below) up to about 80% or plug it in when you phone is about 30%, and it will literally stay between 25 and 30%, right at body heat, while streaming AND surfing for 2+ hours. Very cool little thingamajig/doohickey.

Wow, excellent question! I wonder the same thing. Is it the plug that controls the amp output or is it the usb cable that does? It would be nice to get a longer usb cable and not worry that there will be a problem.

MicroUSB cables are standard. Any quality cable will work. I got a 6-footer from Amazon to replace the pitifully short cable that comes with the phone. For that matter, any quality USB charger will work. The voltage is standard. Differences are in current output. The OEM chargers that come with the phone are 750-850ma, usually. The USB port on your computer typically will not put out that much current, nor will some car power adapters, so they may not charge as quickly, or may not charge at all while the phone is in use. However, beware of overly cheap chargers and cheap cables. If they are poorly made, they may not meet specs.

I'll agree on the cables, but not the wall warts. The one that came with my Maxx is 750, whereas the old one from my D1 is 850. No way am I going to take the chance of plugging my shiny new Maxx into an 850 and trusting that it won't overdraw - not worth the risk. I'd trust a Moto charger that's below my OEM charger amperage, but never one that's higher.
I don't like it because the USB cable is simply too short. Often it's not long enough to reach from a socket to a desk or night stand.

Suit yourself. Motorola makes several universal chargers of varying current rating that are razr compatible (for example, the p833 and p933). The key factor is voltage, not current, for Li type batteries, and that's managed by the charging circuitry on the phone. I'm using the Moto charger (fmp5504a universal charger, 850 ma moto oem) from the dock of my previous phone because I need more than one charger (home and office), and it works fine with the Razr Maxx. The difference between 750 and 850 is negligible and the circuitry on the battery regulates current draw and voltage. USB voltage is a standard 5 to 5.1 volts; the internal circuitry on the phone steps it down. The rating of the charger is the max it can deliver, but the actual draw is limited by the circuitry on the phone as part of the charge cycle. See All About Battery Chargers and also Charging Lithium-Ion Batteries. Moto advises against using non-moto chargers (product liability no doubt), but I'm fine with using the moto charger from my last phone. And the charger my local Verizon store sells for the car dock isn't even a Moto.

Even better price on Amazon, going to have to order one of these for just in case situations.
My current go bag, which sees almost daily use, contains a moto dual usb wall adapter, 3 moto usb to micro cables (pair and spare), my p893, and a spare micro sd çontaining the 902 fxz, the 905 ota, a full TiBU of my 905 install, and the 2233 ics leak, and a cd with rsdlite and the most current moto drivers in 32/64 for windows.
