There are around 12 major plug types in use today, and even worse, these sockets are divided into two main groups: the 110-120v fellas, like the the ones we use in North America, and the 220-240v plugs, like most of the rest of the world uses. patibilities:UK: Bahrain, Bangladesh, Belize, Botswana, Brunei, Cameroon, CHN, Dominica, El Salvador, Gambia, Ghana, Gibraltar, Grenada, Guatemala, Guyana, HK, Iraq, Ireland, Isle of Man, Jordan, Kuwait, Lebanon, Macau, Malawi, Malaysia, Maldives, Malta, Mauritius, Myanmar, Nigeria, Saudi Arabia, Singapore, UK US: American Samoa, Antigua, Aruba, Bahamas, Bangladesh, Barbados, Bermuda, Bolivia, Brazil, Cambodia, CAN, China, Colombia, Costa Rica, Ecuador, El Salvador, Guam, Guatemala

The first thing I found was that it was unable to recharge my Barnes & Noble NOOK HD+ Tablet (which requires 2A) at full speed. It does not matter if I use the two ports labeled `i' (for Apple?) or `G' (for General?) - the results are exactly the same. This is disappointing, but at least it was able to recharge my other tablets at up to 1.5A each.I then connected two tablets plus a cell phone to this charger, with a combined current of 3.5A. Everything appeared to be charging just fine initially. After less than one hour, however, the blue indicator light on the charger went out. I removed the charger from AC socket. The unit was very hot and there was a strong odor of burnt circuit board. Evidentially, the power converter overheated from the heavy load and burned itself up.I cracked open the case and found a damaged THX203H control IC inside. This IC is rated for 12W continuous, 18W peak output power. That explains why it was able to supply 3.5A for a short while (5V * 3.5A = 17.5W), but eventually burnt out.

Bottom Line:The TOTAL output current from 4 USB ports is limited to 2.1A max. That means if you connect 4 devices to this unit, then each device is only allowed to draw 0.5A. Conversely, if you connect an iPad to one port, then you are not allowed to use any other ports. In any case, I find it inexcusable for an AC power converter to have no thermal protection. So I cannot recommend this product.I later purchased the Poweradd 25W 5V/5A 5-Port Desktop USB Charger and found it to work as advertised. /review/RPVC2UQAF1PV1/This is now a basic part of my travel kit.

Typically, these operate with a wide-range of AC inputs from 85V to 265V AC (for worldwide source voltage compatibility). Generally, there is only one output in the 12V to 20V range which is compatible with most battery packs. Typically, above approximately 90W, Power Factor Correction (PFC) is used. One of the most desirable attributes of an AC/DC supply is high efficiency. To realize this, Zero Voltage Switching is incorporated. Specifically, this Active Clamp and Reset technique features the benefits of Zero Voltage Switching, simplicity and few components.
