    Insignia Portable Charger - works well but too big

    Great charging capacity and works very well. The size and weight of this is hard to manage as a portable device. The price was better than other comparable items but considering the size and weight now it may have been worth it to spend the extra money....

    Love this thing! Works fantastic and holds a charge for last a very long time . I ended up using it and allowing my coworkers to charge and still had some juice when I got home. Well worth the $

    Did the job I needed it to do. I've only needed it once and I didn't pay attention to how long it took to charge my phone or know how many times it can charge up my devices before it needs to be charged. I hope to give better info after my cruise vacation.

    Purchased for a trip to extend the battery on iPhone while out on excursions. Has plenty of juice for games and photos while away from power outlet for a full day. Highly recommend this for anyone in need of additional power to make it through the day.

    This is a powerful unit for charging two items at the same time. There are two strings (high/low) depending on what’s being charged. I keep it in my travel backpack case for quick charges. It is larger than normal; so keep that in my nd.

    Good solid battery pack. One doesn't charge fully. 3 blue dots but it's fully charged no matter how long you charge it. The pack will charge meet Samsung Galaxy phone many times before it needs to be plugged in.

    I have only tested to see if it works. It charged two phones at the same time. I bought this because we lost power for two days. It is heavy and has lights to let you know the charge.

    So far this charger has met expectations, my previous charger is still going strong. There's no fast charge but it still does a great job charging relatively fast. I have no qualms about buying Insignia brand chargers.
