Does the job Both items work fine with my Samsung YP-T10. Because the Mains adapter uses (supplied) plug adapter in the UK, the USB socket ends up on either side which is convenient.
Product did not work. Neither the plug nor the cigarette lighter adaptor worked with my Samsung Z5 or Motorola Razer V3x phone. Both devices think that they are attached to a computer, so something funny is going on here. However attach either device to a computer or the Motorola's USB charger plug the devices charge. The adaptor is obviously not a true USB charger that adheres to the USB specification, else the devices would charge. You may be lucky with your USB devices, you may not, personally I wouldn't risk it.
Portable USB charger I needed a USB charger that could be used anywhere without the need for a computer and found this one whilst browsing, read the reviews and decided to order. The delivery was prompt and it was well packaged, have used it several times already and it works really well. This is an ideal item to take on holiday especially if you have teenagers who can't function without their mp3 players.
Couldn't do without it! Took this on holiday to charge my Sony MP3 Walkman and found it invaluable. I now also use the car charger to keep it "topped up" while I have it plugged into the car stereo. No problems whatsoever.
