  • very nice power bank

    posted by Mar595

    This is a very nice gadget for your recharging when you travel. It charges with you usb or electric network and sun. It takes a while to fully load as it is a large battery, but then I can load my phone several times to 100%.Extremely good value for money. As said, the charging itself takes a while to get the full 4 lights led, as in fully charged. But hanging my phone on it, the phone reloads very fast. I also recharged a tablet etc. Charges very well. Reloading by sun is possible....but does take forever, so that's definitely a case of emergency. You can load till one led and recharge your phone. That works brilliantly.
    Very good product. I reordered as I want to give it as present to my friends. Love it!
    Value for money. Great product. Can't go wrong with this for you phone. And other energy absorbing things!
  • Super gadget!

    Well made, plastic don't feel cheap, battery holds well inside (18650 exactly, you can't use protected cells, they are too large), I use it also as 18650 charger for my flashlight, batts are charged to full within 4 hours max. Also strap and short microusb cable are great things, well made.
    There are 2 diodes indicating charge, red and blue. They are dim for normal day (in dark room they can be nicely seen through white plastic) so i made little hole just where diodes are, and I can see charge indication even when its day. I also cut small groove to easily remove back door when needed.
    I will try to submit video review, be sure to check it for more info.
  • Nice but chinese instructions?

    plugs into wall outlet, I believe it is 110-220 compatible as I am using it through 110. Securely holds battery in place and has a wide range between connections to allow for many types of batteries.
    Should be auto polarity but can't really tell if it is functional as so. Also can not confirm if it has any safety features that will disable the charging when complete.
    Being the second device of this nature I've bought, the first being a usb plug-in it has definitely been worth the money.
    I recommend researching the device for the instructions to make sure it is what you need.
  • This is a must have if you have a cell phone!

    I bought this device because I wanted a power bank for my phone. I already had the proper battery to fit it, so I bought the bank that came without a battery. Battery fit fine, and the blue light came on when plugged into the USB, indicating charging. It shines through the case, so is not very bright. You can see it ok, but it won't blind you! After a few hours the cell was charged, and I attached it to my nearly discharged Samsung phone. About an hour later, the phone beeped to indicate a full charge. It really was full, 2 days later and the phone still shows almost a full charge. I charged my Syma helicopter with the power tank, and after about 30 minutes, it was charged enough to fly for 6 or 7 minutes - basically a full charge.
    Got a Cell Phone? Or a RC helicopter? This will charge either, and is a real bargain for the money. Remember you need to have or buy a battery for it - DX sells them, too...
    Just get one!
