    I haven't used this charger that much, but i am liking it. I do think it takes a long time to get charged up if you drain the battery but thats not an issue for me. just remember to charge it up before those big trips.

    I got more than I paid for. This simple device works as stated. Be careful to new users that it has the amount and type of connectors you need.

    hard to figure out at first, directions are not specific or intuitive. once figured out, it works fine. Takes a long time to recharge back up, though. all my other chargers could recharge in less than 30 minutes. This one can take a couple of hours if connected to a laptop or 8-10 hrs if connected to a wall plug.

    It isn’t a bad battery by any means. I have another I’ve had for years that’s 26K. This is 20k and you can tell the difference in regards to the amount of charges you get out of it. Still a good battery. Slim and lightweight is nice also.

    Came very quickly. So far what little I have had a chance to use it I am very satisfied with it. It will come in handy with all of my travel for work. It is a pain trying to find a place in the airport to charge my electronics.
