Question: Can anyone tell me if this is also a 220v or just a 110. Thanks!
Document: But it's interesting. Also, twice I've found a message that charging was suspended because the voltage was too high. That said, I can't tell that there's any harm to my phone and while it's mysterious it still does the job nicely, and we enjoy a central place to put our devices.
The auto-off feature, while saves you money on electricity and it somewhat &#34;green&#34;, also fails to completely charge one of my devices. I have a NewTrent 12000MaH battery pack, which will only charge about halfway when plugged into this valet. Other than this miniscule issue, I would recommend this to anyone.
would recommend to anyone in a heartbeat.
If anyone is looking for their cell phone, check the charger. It is still working reliably. I bought several other mini usb cords for it and am using all ports. Nice to have, worth getting.
Great environmentally friendly product. Came with two short generic usb cords for your devices. Highly recommend this for anyone who has multiple devices and needs a charging station for all of them. Love the design of this product. :D
Perhaps it may have a few minor limitations depending on how you use it, but with a bit of common sense you can get past some of these perceived short comings.BTW - Has anyone seen my charging station?Amanda Richards, July 2, 2011
Before making this purchase, I read the description and looked over the manual. As far as I can tell, the Valet does exactly what it says it will do.I keep in on my headboard. The charging pad comfortably fits an LG phone, an iPod touch, an iPhone 4 and a bluetooth headset. I keep a little additional space next to it for a Kindle 3G.
All charged up quickly and efficiently. There is a power on switch, and the Valet turns off after all connected devices are charged.Some minor caveats: You have to use your own cables for most devices, and on mine they are dangling about. Not too attractive, so I'm going to look for some short cables to keep plugged in. The power indicator is not very bright; you can see it in the dark just fine, but in normal light it is hard to tell if the Valet is on.
Got this for my son for xmas. He loves it and most of all it takes very little room to use. And it works for all his toys! He was glad to get it. Thanks
This product is a great addition to anyone needing a charging station. It is able to hold a lot of cables well and not look cluttered. It is great on energy saving/battery maintenance (not good to leave something plugged in for hours after it's fully charged). One limitation is that it could not pump enough juice through it to charge my Samsung Galaxy Tab 10.1. I have to still plug that one into the wall, which is annoying but acceptable.
Answer: Works either way
