USB chargers are everywhere. They’re online, at your job, in your home, and in any electronics store. Typically, we don’t pay much attention to them. As long as they charge the phone without mucking things up, most of us are pretty happy. However, how well these chargers work is something that can be measured.

Ken Sheriff’s Blog recently conducted a study to see which chargers were the best. For some, it was necessary. Some chargers work fine the way they are. Some may not deliver adequate power, mess with things like touch screen use, and even self destruct.

The criteria for the rankings are pretty in depth. Tests were conducted in efficiency, delivery of advertised power, power quality, power curve, and there was a general analysis of the hardware. During the tests, several OEMs are represented. They include Samsung, Apple, Monoprice, HP, Belkin, KMS, and Motorola. Included also are a few counterfeit chargers to see if they can compare to the OEMs they’re ripping off.

Which of the chargers was the best?

According to the results, HP, via the HP Touchpad, scored the highest in all fields. Who’d have thought HP did something right with the Touchpad? Apple, Motorola, and Samsung all scored very high. In fact, in most results they were nearly identical to one another. In the mid-range, Monoprice, Belkin, and KMS were average or better. To the surprise of no one, the counterfeit chargers were garbage.

The non-counterfeit chargers did pretty well in all the tests. None of them were deemed unsafe, even if some were more efficient than others. The counterfeit chargers, though, showed that they are a real danger to pretty much anyone who uses them. While all the aforementioned chargers scored three out of five or higher, none of the counterfeit chargers made it passed two out of five.

So the lesson is, spend a few extra bucks and buy the real thing. The fake ones could cause some real damage to your property. Has anyone been fooled by the fakes before? Let us know.
