Excelente , cumple con lo publicado,

Doesnt display mah which is what i needed this for. Displays absolutely everything else but. Annoying it doesnt show basic mainly used use case of battery capacity, but makes you work it out from other measures. Has many screens, not on any of them, cannot set it to display mah, very hard to use overall vs many other similar products - so expensive and got a lot of stuff i dont need with it, and not the basic function i do need.

Excellent product

I bought the FNB58 as I'm into small electronics and wanted a tester to test cables, chargers, etc. This thing does it all. From simple voltage/current/wattage readings to battery capacity measurement and fast charge protocol control, there's not much else you could possibly need. The feature set is incredible, and the UI is easy to use, although the manual isn't really much help: I looked to YouTube reviews and tutorials to learn how to use it: Pros: Small form factor, large display Physical buttons have great tactile feeling Measures and tests just about everything Cons: Manual is pretty much useless. More expensive than others (but with better features so that's expected) No internal battery (some functions will require a seperate cable and brick to power the device). There is a different variation of the FNB58 with Bluetooth and an app for your phone. The casing on the Bluetooth model is a lighter blue/grey, as opposed to the black casing this one has. I have not tested any PC connection features, as I don't really have the need to. 2 warnings: 1. If you are using any fast charge feature, make sure you know what you're doing, as it is possible to send high voltage to a device and fry it. There is a warning when entering the menu reminding you to unplug anything connected to the output. 2. Flicking the PD COM switch to on will connect the power from all the ports except the PC micro-USB on the top. When using a feature like PD listener, you should power the device with the PC micro USB port, as it's isolated from the rest of the circuitry. One review I saw didn't do this and sent 20v from a laptop charger into a 5V battery pack. Fortunately the battery pack had over voltage protection, but it's not a risk worth taking. Overall, for the hobbyist with the budget, or the professional repair technician, the Fnirsi FNB58 is a great package that you won't be disappointed with.
