  • Basic battery tester

    posted by gonzo06

    It shows how much the battery life is on a battery, before deciding to throw them out, good build quality, it helps alot if you have a lot of remotes around the house to know which batteries are dead or good
    I wouldnt recomend to buy this item, because you will end up not using it as often as you think since you could easily misplace it

    it works normally like any kind of power adapter, and fits perfectly in my Arduino and from now on i don´t have to always connect my Arduino to a computer .
    I had no problems so far, and i don´t expect having one .
    it´s a useful product if you don´t want to have your Arduino always connected to USB and don´t want to use a battery all the time .
  • Useful for my work

    Help to indicate if your batteries are ok or in need of replacement/recharge. This device is rather important especially if you have a set of batteries which are new and which are dead. Easy to use. Able to read AA, AAA, C, D and 9V.
    Not able to read the round CR batteries. Hope it can be in % reading.
    Useful little gadget for techy people. Recommended item.
  • Good adapter for the price

    Good quality for the price. 9Volts 2000mA adapter is just what i was looking for. I've used it in a amall tv-photo-frame set which required 1500 mA. Now it works perfectly.
    Fast shipping, well packed. It only took one week (to Spain)
    Hope this one to last a bit more than original one (it only worked for one month!!)
