This is a very convenient way to charge your cellphone as theres always a computers are everywhere, but the charge rate is so slow its impractical to depend on. For that reason of the slow charge I gave it one less star. I've used this at work while listening to internet radio which really drains the battery during use. This charger helped keep from draining the battery, but didn't charge fast enough to increase the charge while using the phone at the same time. Another problem I had was the length of the cable, is so short i couldn't lay my cellphone on the desk it had to hang off the front of the computer unless propped up by travel coffee mug. For that reason I had to give it less another star.Being as there isn't anything better out there as convenient charging, this is something i carry around with me and use.
I have been wanting to purchase one of these for a while now. I finally purchased one and am glad to have this charger. When I travel and have to sit in a conference room all day, I can just plug in my phone or headset to this charger and juice up. I recommend it.
I figure this USB charger would still be useful after she's gone back home. But a day or two later, she can't even turn it back on without a re-charge to get some other friends' numbers. I bought it for my mom, who came to visit me but forgot her charger in her home country. USB connection makes it a great accessory for traveling. It's a space saver USB charger. Maybe it's just the battery or my luck. Now it's only good for "one-time-use", while all she does is turning the phone on to get a couple phone numbers from her address book and she would turn it off right afterward. A fully charged battery used to last her a full day with normal usage.
Not sure if it's the battery itself or if it's this USB charger doesn't do a good job. However, I must say it does take super long time to charge my phone. And I love the attached cap. Since she's traveling now and this USB charger is the only one she has, so she has to stick with it for the time being. So, it should worth the money. And for some reason, the battery drain super fast, way faster than usual according to my mom. But for sure, my mom is blaming me ruined her battery life.Reading the other reviews doesn't seem like this USB charger has this kinda problem. Oh, well.
Before this charger I had one that was exactly the same, except it was an OEM version. If you're trying to decide between this and a cheaper, non-Nokia branded version, I recommend getting this one. Fortunately it didn't damage my computer or my phone.So I bought this Nokia-branded version.
It was significantly cheaper, but, as I found out, not as good. No excess heat. It had no Nokia logo on it.
No whine. It always gave off a faint, high whine when I was charging my phone, and after a few months, it would start getting hot every time I used it. Eventually it burned itself out.
Perfect. In this case you definitely get what you pay for.
The Nokia CA100 USB Charger is practical for leaving the phone to charge while I'm in the office or when I need to provide power to a Nokia phone being used as a 3G modem (3G's battery hog).Potential buyers should keep in mind that (1) this is a very slow charger and (2) it only works from high-power USB ports. TIP: if you own a macbook, the higher-powered port is the "front" one (the one closer to the audio jacks).Overall a recommended buy as long as you overpay and get it from a reputable seller like Amazon - eBay may have chaper prices but their CA-100s are fakes for the most part.
