This review is from: Lenmar ACUSB4 AC Travel Adapter for up to 4 USB Powered Devices (Black) (Personal Computers)

This device has 2 amps of power output, total. That means it can charge your iPad at the same rate as the native ipad charger, or it can charge your iPad and iPhone simultaneously, with your iPhone charging at full speed and your ipad charging very slowly. But you've only got 2A to work with, so if you plug in 4 devices, each had better have less than a 500mA requirement.

That being said, it's a great device as it'll put the full 2A to a single port for quick iPad charges. Another great feature of this device, which isn't mentioned, is that the included interchangeable international power connectors plug into the device using the industry-standard two-prong connection usually used on notebook cords, which means you can use a two-prong notebook cord directly into the device for longer reach. A very clever design choice by lenmar, to be sure.

All in all, love this device. It seems to be very sturdily constructed works perfectly for even very high (by usb standards) amperage devices, like the ipad, albeit with the caveat you need to keep in mind that 2A charging limit. It's one of very few devices that will actually put 2A out through a single USB port. Definitely recommended.

Fortunately, mobile devices are finally converging on the USB 5v power standard. Now, if only the world could agree on an electrical outlet standard. This well-made unit addresses both sides of the power adapter challenge. Don't think you'll ever need four USB power ports? At first that's what I thought, too. Now I am already traveling with THREE.

The Lenmar adapter was a godsend on a recent trip overseas. It worked like a charm.

One word of warning: When traveling, one often needs to charge everything overnight. Make sure you bring enough USB cables so all your gadgets can charge at once. The four USB ports are useless without cables.

We recently grew to be a 4 iphone/ipod family. On our last trip, we carried 4 separate chargers to keep the devices juiced up. Spending more time than I cared to, searching for wayward wall chargers plugged into distant hotel room outlets and such, I decided to look for a multi-use charger. My first solution failed, having purchased the Griffin PowerDock 4. I have a separate review there. Then, I settled on this Lenmar charger. It outperforms the Griffin charger at half the price and size. In short, it provides 4 USB charging ports that do what they are supposed to do. They charge. The unit is small enough to travel with. Just be sure to bring the USB cables needed to charge your devices. Another bonus...it comes with international power plug adapters. Note: Kensington appears to be reselling this same device, but with the adapters. Better to buy this one directly from the manufacturer.
