Energizer Universal USB Charger

The Dual Energizer Universal USB Car Charger can charge 2 USB devices at once.

Specifications:

The charger is rated 1.5 Amps, so each of the dual ports supplies 0.75 Amps of power (1.5 Amp / 2 = 0.75 Amps, or 750 milliamps) when both ports are used simultaneously.

0.75 Amps is enough power to charge most devices. To put things in perspective, a standard USB port on your computer supplies 0.5 Amps -Thus, if you can charge a device with the USB port on your computer, you should have no problem charging it with this Energizer charger.

I have only 2 niggles: (i) 2 words: blister package, and (ii) the charger has a smooth and shiny plastic exterior. I would have preferred if the plastic was more rugged in texture.

This charger works flawlessly to charge all of my devices (phone, PDA, bluetooth earphones, GPS, etc.). I couldn't be more happy with it. Recommended.

No big complaints about this unit, certainly beats carrying two USB-chargers on trips. I did note that when I plugged my iphone and ipad2 simultaneously it took the ipad much longer to charge than when it was alone. But it works fine, no signs of heating up, no irritating bright blue blinking LED light to keep you awake all night. Recommended.

Update 3 months later:

OK, originally I gave this 5 stars, but 3 months later it has malfunctioned and no longer charges any device. It makes a buzzing sound when devices are plugged in. No go for me.

The Energizer Dual Universal USB Charger works well during my first day of use. The charger does what it should do charging two USB devices at the same time. However there is a severe limitation the output is rated at 1.5A max, not enough to charge the Apple iPad.

Pros:

Works well with USB devices that does not demand a lot of power. It works with my iPhone, Android phone, Kindle, and Bluetooth headset.

Comes in frustration-free packaging. It is very easy to open the paper board packaging.

Universal input power from 100V 240V AC.

Fold-out plug that does not take any space when folded in for travelling

Overall relatively small size.

Cons:

The two USB ports are rated at 1.5A total. According to the original iPad charger, you need 2.1A to charge the iPad. Not being able to charge the iPad is the reason that I have to give it a three-star rating. Basically it does not enable me to carry only one charger. (Other users pointed out that the charger does charge the iPad. The iPad screen must be turned off in order for it to be charged by this charger. The trickle charge mode takes a long time to charge the iPad, and the iPad shows "not charging" although the battery does get charged over time. Upgrade to 4 stars because of this update.)

Although it does not take much space when plugged into a wall outlet, the footprint is relatively big and it will block two outlets if used with a power strip.

It gets very warm when charging two devices at the same time.

This is the first time I write a review about anything, ever, and I'm doing so because of how much I regret buying this charger. I figured that since Energizer has a good reputation I was going to get a quality product, boy, was I wrong. This thing makes the most annoying buzzing sound when I try to charge anything with it. Like most people I prefer to leave my cellphone charging overnight on the nightstand, but the few times I did while using this charger I woke up with a headache. I've tested it with other devices and different outlets, always with the same results. The worst part is that sometimes the pitch of the buzzing changes, thus becoming even more annoying. Other than that, it works as advertised, but hey, so did Chucky.
