Yeah, it should be fine.
The charger limits the power that charges the battery. All it needs is a 5v source that can deliver at least 500 mA.
I use the Triton charger on my Triton battery, from a variety of usb power (wall adapter, car adapter, PC port, laptop, etc). Works fine. You don't need a high power adapter either (high power adapters can deliver up to 2'100 mA), but you could use one, if you wanted to (it'll be under-used, which is OK).
