    Resolver and rescue my smart phone or other else device when battery is near to death. Good idea if you travel to long distances (airplanes, sailboats and trains) when you did not find out an energy source; but in the drawback last in life recharging back up electronics devices untill 3 hours and then is dead. Unit need improvement further more extended capacity time length power to heavy duty on demand systems.

    Good for emergency charging

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    So far I have tested it on two different android phones, both times I only managed to get around 50-70% re-charge before the Dynex unit dying. Keep in mind that both times the phone was still on, so the re-charge percentage might be slightly higher if the phone was shut off. How fast it re-charges the battery greatly depends on what kind of phone you have. My HTC one x with an internal battery took around 4 hours to get a 60% recharge. The slow charge has more to do with my phone since it also takes long to charge with a wall plugin. My Motorola Atrix 2 with an external battery took less then 2 hours to get a 50% recharge before the Dynex unit dying out. Recharging this Dynex unit takes virtually the entire day to get it ready again, once it has been depleted. Your better off carrying a reserve battery if you have an external battery phone, although this might be a cheaper alternative. Highly recommend for those with an internal battery phone who wants to maintain their charge or use it as an emergency backup.

    It takes awhile to recharge after you've used it once. Only good for one single charge.

    This is a good choice to make but, it only makes one charge and then it's out. So if your expecting this to charge multiple times in a day this won't be the right choice.
