30W 220V Electric Vacuum Solder Sucker Iron Desoldering Pump Repair Tool
A part of the review has been auto-translated.
I bought a step-up transformer to provide 220V in order to use this item in the right way (I live in Canada, here we have 110V). This item has inside a kind of rubber accordion boot driven by a solenoid. When the solenoid is energized, the rubber accordion boot expands and it creates a vacuum for desoldering. This is the idea because in practice, this item DOESN'T work. The solenoid doesn't move straight inside the coil from one end to the other when it is magnetized. The solenoid is just buzzing erratically when you push the push button and the vacuum is not there. This item makes only noise! Not happy with what I've got.
Good unit
It's really cool.
Works a lot better than the purely mechanical spring-loaded solder sucker I used before because the electromagnetic suction plunger provides great suction. It takes some getting used to though, because as soon as you release the suction button it has a tendency to spit molten solder back out, and if you're still over the board you're working on when that happens you're likely to make a mess that's going be tough to clean up. Once you've trained yourself only to release the button in a safe space, you should be fine.
The order arrived in a short period of time The packaging is good and the product has been tested and works well Thank you banggood
