I purchased the XB2L3 to check Li-ion cell capacity and discharge Li-ion cells to a set voltage for storage. Using one of the 7 ohm 5 watt rated resistors gives a discharge rate of just over .5 amps. Running in default mode aka down to 3 volts the capacity reads about 140 mAh less than my Xtar VP4 Plus reports. This is using the same 3400 mAh fully charged cell each time. The Xtar reports 3340 mAh and the ZB2L3 reports 3197 mAh. Which is correct? Close enough for me. The discharge to a set voltage for storage works well just set the voltage and hit OK. The discharge stops when the set voltage is reached. If the battery is removed immediately when the discharge completes the voltage will rise slightly after a period of rest so keep this in mind, less than .1 volts in my testing. If you leave the battery on the ZB2L3 longer it will start discharging again when the voltage rises. This is a great low cost way to test and ready Li-ion batteries for storage and you can't beat the price. Just add a Battery test rack like in the link below or similar, some wire, a USB power source and a Micro USB cable and you are all set. https://www.banggood.com/Four-Wire-Battery-Test-Rack-Battery-Clamp-10A-With-Terminal-26650-18650-AA-AAA-p-1310582.html?rmmds=myorder&cur_warehouse=CN

This is a early version of the FW21 that has a longer battery tube than the later production FW21's have. This version does not support unprotected 21700 batteries as they are too short causing intermittent operation. If you can find high drain protected 21700's you should be OK. Unprotected 18650's will work with the supplied adapter though what is the point. Might as well by a FW3A. Wish I had known this before hand.

I was worried if these would work on protected button top 21700 batteries for nothing as they will fit no problem. These are not cheap low quality holders as most others I have seen are. They work very well and are well worth the money.

They look and work great. The only thing I do not like is they are hard to remove from the case. The magnets are so strong and the way the case is made makes it hard the get a grip on them.

Works well though it is very small and hard to read for my old eyes. I knew it was smaller than a UM25 or UM34 but its way smaller. The android app works well for me on my S10+. I can also use the app on my windows 10 PC. I was easily able to update the firmware without any problem. If you need a USB C DMM this is a good option IMO.

I purchased the XY-UDT as a power supply and battery charger. My sample has some minor warping on the face of the device. Its cosmetic only and dies not detract from its usefulness. I have used it to charge Li-ion cells and it works well. It took a bit to figure out how to operated it but its really simple once you get the hang of it. I set the charge current to 1 amp and the voltage to 4.2 volts and it charges CC/CV just as it claims it does. Next I'm going to top off a lead acid battery with it. And I want to try running some 12 volt fans off of it using the PWM mode. Overall a nice piece of gear for the money.

I normally only use high end soldering irons and guns but this little iron caught my eye so I ordered one. I'm glad I did as it heats up fast and seems to regulate temperature well. For the money it can't be beat IMO.

I might never need this but you can't beat the price so I had to order this as a spare for my MUSTOOL MT883.

In my sample the laser is aimed off to the right of center making it of little use. Otherwise it seems reasonably accurate and the display is easy to read.
