Be Careful

Jmac—October 6, 2025

Works great BUT my first one had a broken on/off switch and wouldn't work, too a long time to figure out the issue. The second one works great BUT the power supply is one (1) watt and wasn't enough to power the laser and motors, so I replaced it with a 10w power supply (overkill). If you need to rewire it there isn't any information about the laser and how to rewire it, you need to look it up on the Ali Express site, the information is there if you request the information form the manufacturer (they don't respond on the Amazon site).

Whole lot better than using a wall wart

Kevin R. Colvin—November 1, 2025

Price was great. Worked better than expected. So happy I purchased 3 of them to replace 3 wallworts that were going bad. By them having a standard plug receptacle, it made it a lot easier to use my power strip without losing other socket space. Read more

I can't find a charger that works for my computer

Clickaholic Diva—November 20, 2025

I bought this charger hoping it would power my 12V laptop (which requires 12V ⎓ 3A), but unfortunately it didn’t work for me. The voltage and amperage on the adapter were correct, but the barrel connector tip was not the right size for my laptop’s charging port. It looked almost identical, but the inner diameter was just slightly off, so the plug wouldn’t make a proper connection and the laptop wouldn’t charge. If you’re buying this for a device that uses a round DC barrel port, double-check whether your device uses a 5.5×2.1mm or 5.5×2.5mm connector. They look nearly the same, but that tiny 0.4mm difference can make the charger completely unusable. The charger itself seems well-made, but it’s not truly “universal.” Make sure the tip size matches your device before ordering so you don’t run into the same issue I did. Read more
