Basic Chinese Multimeter Tester Comparisons

A basic comparison of GM328 transistor tester/ ESR table / LCR / frequency meter / square wave generator
MK-328 TR\LCR\ESR Transistor LCR ESR tester semiconductor device analyzer M100 C
and Auto LCR Digital Electric Bridge Resistance Capacitance Inductance ESR Meter
My Brymen 867s is made in Taiwan, is that China? There is the link anyway as it is in the video.

Do not pay ridiculous prices for these as they can be found at very reasonable prices on eBay. Shop around.
Not all functions tested as video is 50 minutes already. Will test the rest in another video.

“RD DPS5015 Constant Voltage current Step-down Programmable digital Power Supply buck Voltage converter color LCD voltmeter 15A” from AliExpress (link below)
i want to use it with my solar battery bank. So I need to boost the battery power first and manage it before applying that power to the DPS5015 for me to use.

Charging non rechargeable battery

If you can see a problem with what I do leave a comment as it is far more constructive and intelligent than thumbs down.
WARNING Non rechargeable battery’s should NEVER be charged in a battery charger.
This is how I charge MY non rechargeable batteries. I do not suggest you do this as it can be dangerous. If you do, be sure to supervise the charging process.
