  20. Customer

    Came quickly. Everything is fine! Thank you)

  21. M***a

    ok

  22. I***v

    Tuned to 5 volts. The most interesting is to check the low voltage cut-off on the battery. They write that no. If not, it’s very bad. Although the chip is the same as on the regulators with the compartment. There are sites for soldering, i think it can be possible to solder that to turn on the cut-off on low voltage.

  23. P***y

    Already in which time i order from this store-everything is fine in all positions

  24. I***l

    Sent quickly, came in three weeks, track to the border. The product is very interesting, until the hands to apply, took to transfer multimeters to power from lithium

  30. Customer

    excellent product, not tested yet

  31. S***a

    Used by self-made 9V battery that can be charged. Since it can be boosted to 9 V in combination with the Lipo battery, you can make your own non-disposable battery.

  32. A***v

    The goods did not come, but the store returned the money without waiting for arbitration.

  33. N***a
