There are many high-quality USB chargers on the market (Anker is one brand) and most have amp ratings higher than the 1A that the stock XP charger provides. Am I correct that these chargers are perfectly OK for use with the Deus? My understanding is that the battery will draw what it will draw (based on the charging circuit) and the higher amperage is not "pushed" into the battery. If someone has authoritative info to the contrary, I'd love to hear it.
