So basically there is no difference in buying a vehicle charger at VZ for $30 and buying one on Amazon for a few bucks other than the fact that you pay $25 more at VZ? Just wondering if these non-verizon chargers are of equal performance and will not harm the phone. THanks again!!!
Keep in mind that the phone actually does the charging (the "chargers" just provide the juice.) all chargers (cheap and fancy) have different specs.
As long as they are rated over 4V (voltage of the Inc Battery) they will work and (almost?) all micro usb ones will be.
The "big" difference is how much juice they CAN pull (how fast they will charge the phone.)
Stock HTC chargers are rated at 1A (1000mA). A lot of usb/car chargers are in the 500-700mA range. They will work (all of my BB stuff does just fine) but it is a slower charge.
There are also a bunch of reports of the Inc being finicky with usb chargers (both mobile and wall). I have had freezing issues with a couple different usb car chargers, others have been hit or miss with usb wall chargers.)
One of the nice things is that so many devices have jumped on the micro usb bandwagon, so there is a much higher chance of forward compatibility for the chargers you invest in for this phone.
Spending $12 (like I did today) for a quality 1A car charger is a good investment IMHO. Spending $30 for a VZW wall charger, not so much. Buying the $2 monoprice pieces, low risk and "if" they work you are good.
I always spend a bit more cash of car chargers due to the abuse they take. Wall chargers often are plugged into the same outlet for their whole life and don't get the wear travel chargers do. The dual travel chargers are nice, too (I have a couple BB ones always packed).
The inc will, obviously, also charge just fine (if a bit slowly) when plugged into any usb port you may have handy. I "think" usb ports will provide 500mA to attached devices, so plan on roughly twice the time to achieve the same charge as a 1000mA wall/car charger.
