6 customers mention3 positive3 negative

Customers are mixed about the wire thickness of the power supply. Some mention that the wire for the barrel connector looks substantial, while others say that the insulation is thick yet the wires are so thin. The included wire assembly uses incredibly fine gauge wire and very few strands, making it possible that the wiring can't safely handle the advertised amperage.

"...Wire for barrel connector looks substantial, but then you see it is all sheathing and the actual wire gauge is 22-26...." Read more

"...The insulation is thick yet the wires are so thin, I wouldn’t even trust putting 1a through them, it is a potential fire hazard...." Read more

"Great direct wire solution for a car!..." Read more

Knowing it would void the return
1st off, nice little box. Secondly it's the bare essentials, which is what I was lookin 4. BUT! upon trying to use this and having everything plugged in, the blue light kept turning off and I was losing output power. I pushed on the 5.5mm plug and I got power again then it shut again. Well, we all know what that means right? Luckily they assemble this with 4 screws so I could take it apart. Sure enough it had a cold solder connection on one leg (the ground side ) of the 5.5mm socket. I thought to myself, " yep ! Just what I expected". So I got my soldering iron out and did a 1 minute repair. It now works flawlessly (or as expected). DONE!Take this review anyway u want but to someone like me its just another example of today's manufacturing flaws but this one was a easy fix. I mean $8 ! Most people would have returned it or threw it out. Ha ha ha! Isn't knowledge wonderful. lol 😆

1.0 out of 5 stars Defective unit ruined my other electronics….
Reviewed in the United States on February 23, 2024
I made sure the polarity is right and hooked it up to my 12v signal on my escooter controller and it shorted, ruining my controller. To make sure I connected it correctly, I hooked it up to a 12v battery and the wires were overheating. Reversing the polarity caused sparks so I really know I connected it right. Other concern is the pigtail is using probe wires commonly used in voltmeters just to detect signal. The insulation is thick yet the wires are so thin, I wouldn’t even trust putting 1a through them, it is a potential fire hazard. Now my scooter is bricked. Lesson learned, always test directly from the power source than to trust the unit will work.
