    This little unit and the battery that came with it are both great. The battery is comparable to the battery that came with my phone in terms of charge time and the battery charger works great. It's takes several hours to fully charge a battery, but the indicator light is pink when it's charging and blue when it's done. Very easy to spot from across a room. Sometimes, I use it as a nightlight to navigate dark hotel rooms when I travel. It's quite bright, but I see that as a positive thing.

  • it's not perfect
    Verified Purchase

    The unit worked great until, after a few months, I pulled it out from the outlet and one prong stayed stuck in the wall. Then, after fixing that problem, the charger stopped making a good connection with the battery requiring some wiggling and gentle pressing on the unit to get the pink light to go on. Now, after describing this, I am here to order another because the price is so reasonable and just hope that it holds up better than the first one. The bottom line is that I do not want to get rid of my Thunderbolt phone yet. Getting the extra battery is definitely worth it and the fact that the first charger still actually works, though not without problems, I should have a charged battery or two at hand. As the saying goes; 'You get what you pay for.' P.S. I was pleased that my extended life battery can be charged in this unit which was a plus.

  • Excellent Value For Price!!
    Verified Purchase

    I had already had a portable battery charger such as the one in the picture, and it was faulty. This product cost way less, especially for the fact that it was bundled with the spare battery, and has met and exceeded my expectations. You will not be disappointed.

    Got this as a spare charger. It works great. I love that the light displays when it is charging and when it is complete.

  • product is excellent, works as expected
    Verified Purchase

    This is a great product. Not only is it cheap (!) but after you let it go through the initial charging (about 6 hours) it works as good as the original battery that came with the phone. The charge last for a fairly long time and is great alternative to replacing your phone if the charging port is starting to go on it.
