  • I have long wanted to make a tester to check the batteries.

    posted by pv2dx

    1. tester does not need a power supply2. Tester is easy to use - even a beginner will understand how to use it3. tester is small and light - it is important to carry in a backpack4. Tester is designed for a wide range of sizes of batteries checked
    Tester will take its rightful place in my arsenal of instruments "must have"
    I am very pleased with the purchase of this tester
  • Good product

    posted by Guido2008

    It is a very useful tool for the home. When you have many batteries for toys, remote controls, etc. and do not know which are good and which already have to recycle. Good build quality. Measures virtually all formats of batteries, including batteries 9v and button type. It is advisable to have on hand when needed.
    I found it very useful to classify about 50 batteries of all kinds. Once the task is done looks forward to re-use, which is not so common.
    good product
  • Good adapter for the price

    posted by manuke

    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!!)
  • Excellent

    Product of excellent quality good amperage and voltage perfect for many uses in the world of robotics.
    If you intend to develop a robot that uses Arduino, or automating this home, you will need a source of good nutrition, which is a bank that supports your project, and an appropriate voltage to your Arduino. This source is ideal for you to do this with confidence, without worrying about extra fonts or anything like that.
    I needed to connect my arduino source, since I am developing a series of new projects here in my house.
  • Great Arduino Adapter

    posted by teo1992

    It does everything it should. Feeds my Arduino without USB. The build quality is very good. There is also an LED that indicates proper operation. Since I live in Europe I also bought the adapter that allows me to use it. A marvel. The price is great. It works perfectly with hunting 9V to 230V 1A.
    It 'an object handy for those who Arduino, a bargain. Very useful. Good product and great price. Buy It.
    Buy It.
