  • too small for galaxy s4 !

    posted by BeeOne

    nice build, can charge most of cell phone battery with it's moving charging pins
    the charging pins doesn't stay in place, so you have to replace them each time you plug your battery in the charger.
    This is a good product if you own a cell phone with a normal sized battery, but if you have a galaxy s4, forget it, this product is not for you.
  • Universal Cell Phone Lithium Battery Charger with USB Power Port - Purple

    okay cool, I like the lights out when he starts charging the battery, it is noteworthy that when charging the battery has to be positive (+) and negative (-) and when you place it well, as I just mentioned catches on esque red when the battery is low and if you have not but connect it catches the light and is well connected flash red and blue (purple) and that means the battery is charging.
    is very useful because I was looking for my camera charger for a while and could not find me and this served
    highly recommend it for all types of battery

    Huge capacity for the size/weight. For the few things I need to use it with, it doesn't add much size, but they will run a very long time.Can provide a wide range of voltages.Charges reasonably quickly for the capacity, and indication is clear.

    Wide range of adaptors.
    I would rate it higher if it included the AC adapter as pictured here (but not in the accompanying documentation). Even higher if it also had a car adapter. It also doesn't give a range around 18v/750ma so I don't know if my 19.5v laptop adapter would be safe, or if my 16.5v would work.

    The "voltage range" typically will mean, except for 5v (usb) devices, that it will be pack->adapter->device instead of pack->device. I don't know how they could keep it small yet allow finer setting of the voltage, but that is the only real technical complaint I have with it.
    As a USB charger, (if you have an 18v power supply available) I don't think there is any better pack for the money (under $10/1Ah). And the capacity is enough to run things for hours. They should include the recharger.

    Auto-polarity.Easily adjusts to all cell phone batteries I own.Two LEDs (one red, one red/green) show charging state.
    I had owned another charger (SKU 81076) which went up in a bang and a cloud of smoke after little more than a year, so I went for another one. At the time of purchase, there were no devices with EU plugs available, and I chose this one instead.I'm a bit worried by the voltages shown on the bottom: "USB 6.2V" reads a bit unusual, doesn't it?
    Once one gets used to what it tries to tell me, it's a nice device.
  • 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.
