Verified Purchase(What is this?)
This review is from: Masterplug SRGAUSBPW Surge Protected Mains USB Charger (DIY & Tools)
Great item, only trouble is I only bought one so my kids argue who can use it. Use it to charge all my USB items without a single issue.
TIP: I dont know if this is right or not, but I was recommended to use one of these rather than a computer USB as it seems to charge completely and more 'accurately'. I put this to the test with my garmin gps watch and went running exactly the same route. When I got back the watch displayed only 2 bars remaining on the computer charged run and had full bars on the Masterplug charged one. Hardly a technical test but my phone also lasts longer when used with the mains charger through the Masterplug item. Suppose it does make sense when the item being charged has sole access to the electric current rather than competing with the computers power usage. See what you think?
