  • It gets hot approaching 3 Amp

    posted by BabaWoo

    It works. My car cigarette socket reach 14 v, for some reason it would not charge well per se link directly from the socket to my PC, especially when USB devices are connected, although the The laptop is clearly marked "12 V DC input". According to the description it seems what I wanted. Only thing needs to be done is soldering the parts up. Today I took my devices on laptop out for test drive. It seems charging well with all the usual devices hooked up.
    I am wondering how long it would last with this heat.
    Let us wait and see.
  • good stuff to use

    cheap, very small, you can put it into the motorcycle that doesn't have big space, into dashboard, very clear to read the number. no additional power needed. it's good packing
    manual is important to have in this case, because there are many pins
    not bad for price, good quality enough...you can add to your car or motorcycle for indicating the voltage
  • very small drop down PC for electronic instruments.

    Very small , current is enough to cover most applications.With two 18650 batteries I can replace a 6 V 4 AH 6 V lead gell battery and don't have to border about selve discharge as long as this driver is placed AFTER the on/off switch, when not in use it draws a small current and discharge the batteries as well otherwise.Becaus of its very small size you can hide it in alomost any instrument wich is battery operated and after application the voltage is not critical, the output stays the same, the overvoltage of the batteries are transduced in extra working time (amps)and the voltage will be what is needed (can be adjusted but must be below the V in.The high efficiency makes that the PC will not become hot when the max current is respected and under 1A out it stays cool.
    The tiny unit is almost always sufficient to make battery operated instruments and toys suitable for 18650 batterypacks.
    In combination with batterypacks 2-4 18650 cells or more suitabe for almost any situation.As you can see my experience is that almost any battery used systen works better with the combination of 18650 batterypacks ans a driver like this one

    It's very compact, small, useful, automatic, multi-functional, light weight, precise.It has a buzzer, cap-meter...It has a very suit and handy case with magnet clip.
    I didn't like it from the beginning and even wanted to write a negative review. But after some practice I realized it's one of my best buys!For a year or more I had it in my case always with me and it helped me dozens of times!!
    Strongly recommend to buy if you need a compact handy reliable multimeter. I love it!
