Though it’s nice to have portable mobile device chargers as a backup option, you should still invest in a portable USB wall charger for your Apple devices. There’s nothing wrong with portable chargers, it’s just that they tend to be more practical for on the go use. When you’re on standby, whether at home or at work, it doesn’t make much sense to charge your portable charger first through a wall charger, then use the portable one to charge your device. There are definitely times when it makes more sense to get directly to the source, in this case, a wall outlet. Here to serve your USB wall charger needs is the Moshi Rewind 2-USB Wall Charger.
