2 out of 5 eggsNot compatible with HTC ONE?

Pros: Worked fine for a while on HTC EVO

Cons: Get error message on New HTC ONE about being inefficient to charge battery while operating? (Something like that)

Other Thoughts: Anybody else have problem? A remedy?

5 out of 5 eggsThe perfect Android companion

Pros: Charges my phone, then charges my Bluetooth headset. Then still has some juice to charge my phone some more.

Cons: The lights can be a bit tricky. A gauge would have been nice, but I'm not complaining much. It works.

4 out of 5 eggsAwesome! (Except light indicator)

Pros: Extremely portable, great to have when my phone is ready to die at inconvenient times.

Cons: I can never remember what indicator color means which percentage of charge. The larger pack has a gauge which is easier. Wish they would have used a similar design for the smaller tube.

For reference:
Red 1%-33%
Green 33%-66%
Blue 66%-100%
Red flashing 75%-100%

Other Thoughts: I'd still recommend this to others but had to knock off a star for the indicator. If they changed that, I'd easily give it 5 stars.

5 out of 5 eggsGreat. Very useful.

Pros: It is very useful. I first thought that I wouldn't need it as much because I could just sit next to an outlet or leave my phone next to one. Then after buying this you can charge anywhere you want. It charges my Galaxy S3 from 0% to 100% and still has power left on the device. As the charger runs out of juice, there will not be a slower charging pace or a weaker flashlight. It will maintain itself through out the process. Although it has a plastic body, it comes with a thin protective, transparent sticker that will keep it from scratching. The battery won't overheat unless you use your phone for an extended period of time while your device is being charged. I found there to be no cons whatsoever. It is very light and portable. It is about 4 inches tall and 2 inches wide. If you have any questions just ask me and I will try to answer as best as I can.

Cons: The cable that they include with the charger is slow compared to cables that are included with your phone. That's the only con there is with me. There are cheaper and more powerful options in other stores online, but I bought mine when there was a big sale on these.

Other Thoughts: Even when you think you don't need it, buy one.
