  • 18650 charger and emergency power bank for phones and other gadgets

    posted by Daijus

    It charges 1 to 4 x 18650 battery.It can be used to charge a phone with as little as 1 18650 battery.It has battery indicator for each battery.It has charge indicator for each USB outletIt takes protected and unprotected batteries, so you can use old laptop batteries.If you use unprotected 18650's this device protects the batteries against under- and overcharge.
    Why not make both USB's 2A?
    I love it, great device, never worry about phone battery when this is in your bag!
  • Handy little charger that uses regular batteries

    posted by CanadaCG

    This is a very small-sized charger that uses 2 normal AA batteries and provides a USB charge to anything that needs it. It will give you some extra talk-time for your cell phone and even has enough output to put some charge on my Samsung Galaxy 7" Tablet!
    This unit is so small that you can carry it in a pocket or purse easily. A great way to get USB power for whatever needs it using just 2 ordinary AA batteries!Build quality is good and the output seems to be decent. Has a red LED light to show USB power is working - gets dim or goes out altogether when its batteries are depleted and charging stops.
    I'd recommend anybody who uses anything that charges from USB have one of these on-hand. It's low cost and very small, so it's easy to carry around. Provides great power in an emergency or just when you want some portable USB power!(It added 1% charge to my tablet in the time it took me to write this review.)
  • Great for emergencies

    -Charges my phone really fast! -The battery comes with a cap so that you don't damage the microusb. The cap is attached to the battery itself by a string so that you won't lose the cap itself.- The microusb is long enough even though my phone has a case of moderate thickness on it. (I'm not sure about otterboxes).- 4 little lights on it indicate when it's done charging and when it has no more juice left to give. - Very nice and compact size. I can easily fit it in my purse or pocket.
    I'm currently testing it out and had my phone at 64% on standby. It's been charging for over an hour (expressing that it's only at 1 charge light for a good 30 minutes) and my phone is already at 94%. I'm confident that it can charge my phone to full.
    If you know you'll be out for a long day and/or will be using your phone a lot, this should be enough to pull you through.
  • Very Usefull

    - It's very usefull- Quality it's OK- The outlet is an USB port you can use it almost with every electronic device in the world
    I didn't need the cable because I do not have a Samsung but even with the cable it was cheaper than the other chargers.The flashlight is useless... but you can buy a small USB rechargable flashlight and charge it with this.
    I really recommend it if you are going to be away for a couple of days. It's really cheap and it can save you (My GPS runned out of battery and I charged it with this device)
  • Suitable for charging when your on the go

    posted by Darkers

    You could charge it whenever you want when your walking , camping , on a trip and so on. You only require Double A batteries and its very easy to find double a batteries at shops. The cable length is reasonable and the switch is straight forward ; OFF / ON / Lights . Theres an indication red light when its charging when you switch it on
    The light might be necessary if its deem light but if its bright like most of the torch light it could be use in emergency cases which is handy !
    You should get it ! The price is amazing , you should grab them while you can ! For 5 bucks only
