Pure sine wave inverter, or how the Chinese have gotten too bold
7-02-2023, 14:16
Around the middle of December, I ordered several inverters. I also decided to order a couple from a different store than the one I usually use.

An unusual power bank with a QC/PD output of up to 22 W and a few quirks
26-01-2023, 21:03

Thanks to one of my regular readers, I got my hands on a WZ5005 voltage converter. I wouldn't say it has anything particularly special going for it, but it could be an alternative to the popular DPS models from RuiDeng. More on that in the review.

Some time ago, I posted information about a new model of adjustable converter that I had stumbled across completely by chance.

This review will be relatively short, but I'll still try to make it as informative as possible.
