  • This is a great, pocketable power source for charging smartphones

    posted by rlhess

    These (I bought three) are very useful when my two sons run out of smartphone power in the middle of nowhere. I have one as well for the same reason.Very easy to use with devices that are charged via a USB cable. It just inserts between the USB charger and the phone (in essence), although I tend to charge them separately, often from PC's USB ports (as they are handy).
    Please remember to turn off the device when done as there is some drain from the internal inverter circuitry (and LEDs) as long as it's on.The 6000 mAh capacity is related to the cell at roughly 3.4 V, so the 5.5 V output of the unit will be about 3300 mAh, estimating a 90% inverter efficiency. Still, it's 20 Wh of power in a slim case.
    Nice package, I would buy more if I needed one.
  • Great Unit!!!!

    - Great capacity so far- LED capacity indicator lights- replaceable Li-ion cells- comes with li-ion cells (4400mAh)- While charging, the LED indicators strobe to show that the unit is charging the device connected to the USB port.
    - It would have been nice to include a LED flashlight with the unit. A rechargeable battery pack with replaceable cells, high output USB port, and a flashlight would be the perfect unit. I re-charge the unit with my tablet wall adapter as the output is a greater at 1A. This decreases the time needed to charge with the supplied USB to micro USB cord.
    - I would recommend this unit as the li-ion cells are included in the price. The unit works with my iPhone 4, and charges about faster that 1% a minute. With such a quick recharge time I can live with the fact that there is only one USB port on the device.
  • Wireless charging - just like a toothbrush ?

    posted by drutley

    The wireless charging receiver fits well inside the battery compartment surprisingly well despite its thickness. Charging rate is 1000 mA which is half that of the Samsung charging adapter provided with the phone. It has no problem transmitting the charge through the waterproof case also purchased for the phone (item #273766). Should you have your phone in a similar style case you may find it cumbersome to open the charging port to plug in the USB charging cord. The Qi compatible charging mat is slightly larger than phone dimensions and comes with the wall adapter and USB cable to power it. The unit comes with 2 LED's to indicate power to the mat (Red) and upon detection of placement of the phone correctly over the mat, a beep, beep sound accompanied by a green light appears indicating a successful connection and charging begins.
    Inductive charging is nothing new and the convenience of placing your phone down on the charging mat reminds me of a Sonicare toothbrush. No need to replace batteries, just place it back into the holder. The charging works through magnetic transfer of energy where the coil receiver inside the phone placed in close proximity of the transformer inside the charging mat completes the conducting circuit.
    The convenience of placing the phone down on the pad to charge is helpful for those that forget to plug in the USB cable.
  • Works like it should

    posted by Tskunka

    Easy to use. Works as advertised. Nice display of battery life. Small. Easy to solder leads to. Have used it with a few different batteries from 900mah to 4400 mah and it has worked fine.
    I'd recommend it to anyone who likes to build their own. I will be ordering more to build my own set of rechargeable heated glove/shoe inserts.
    If you need it, get it.
  • Mobile power suppply

    Handy device, easily and accurately set. I use it in my car for media player. with 4 diodes I have the input voltage 2.5 volts lowered, then I could adjust the tension nicely at 12.5 volts. because a car when the engine is running 14.5 volts charging. The media player works well and without fault in sound or image
    the device is recommended for anyone with a laptop on the go with the car.
    Handy device for little money, certainly useful for a laptop because they are generally at a higher working voltage than 14.5 volts in a car.
