Charging Tytn II with alternative USB Wall Charger

[earthforge]

Can the Tytn II be charged with other USB wall chargers other than what comes with the package? I have 4 alternative wall chargers:

(1) USB wall charger for Blackberry 8707g
(2) TravelPac world travel adapter with USB charger
(3) USB wall charger for Aliph Jawbone
(4) USB wall charger for O2 Atom Life

I do charge the Tytn II through USB cable connected to my PC. However, I was reading somewhere that this is ill advised, as from a device longevity perspective it is always better to charge using AC Adaptor chargers as opposed charging through the PC, not sure how true it is. I do see under the “Power” settings that there is an option to turn “When device is turned on, do not charge the battery when connected to the PC”, so maybe there is some truth to it.

In any case, my biggest concern is with the wall charger for my Blackberry. The Blackberry seems to be using somewhat different voltage from other USB chargers as I am not able to charge the Blackberry with any other charger other than its own wall charger or through the PC. For example, charging the Blackberry through the TravelPac adaptor more often than not does not work.

Question is, can I (safely) charge my Tytn II with other USB wall chargers? Any downside from using non-HTC chargers? Thanks

Unless someone has already tried one of those other chargers and can post their success here, I would not try it - there have been reports of generic car-chargers and the like frying circuitry on the Kaiser, as the USB power connection is wired differently to some (superficially similar) devices. It's not really worth risking it, when I'm sure you can pick up a spare HTC charger for not much.

I charge from USB everyday at the office (and the mains, when I'm away from work for more than a couple of days) and after three months my battery performance seems much the same as everyone else reports - in fact, better than some. I know opinions differ on whether these modern batteries have any kind of "memory effect" or benefit from a proper discharge cycle etc - personally I've seen no evidence of that. In any case, absolute worst case scenario is buying a new battery some way down the line - given that there are already higher capacity aftermarket versions of the stock battery on sale, that might not even be a bad thing.

With my old Sony Ericsson M600i I used to find that USB charging would never bring the phone to full charge (however long I left it), and the 90-odd % charge it did have would never last quite as long as a proper mains charge. No sign of either issue on the Kaiser.

As long as the charger in question is rated at no more than 5v/1A (as the original Kaiser charger) it should be safe. The Kaiser can probably take more than 1A safely tho, but I won't guarantee that. That said, most wall-chargers are rated somewhere around 5v/1A.
