I want to clarify that I am not an Amazon Vine Customer Reviewer, nor did I receive this product for free. When I saw that all the reviews were from just three five-star Vine reviewers, I should have been more cautious. I purchased this adapter specifically to power my exercise bike, which needs 2.5 amps. Right now, I’m using a 1.5 amp adapter from Japan, and it works fine, but I wanted an adapter that met the required specifications.Unfortunately, this adapter doesn’t deliver. It barely provides even one amp of power. I noticed this because I used to have a 500 milliamp adapter, and back then, the built-in fan on my bike barely spun—it was slow and noisy. With this new adapter, I’m experiencing the same problems. Meanwhile, my current 1.5 amp adapter lets the fan operate smoothly.The only positive aspect is that it supplies the correct voltage. However, the overall build quality feels cheap. The wire is short and thin, raising safety concerns; I wouldn’t trust it for anything long-term. I can only give it one star, and that’s just for the correct voltage.

The power supply does what I need it to, but came with a broken solder joint that caused a very frustrating intermittent until I fixed it.Low price point, but marginal quality. I’m not expecting it to last long.

The display is a little slow on catching up to the adjustment of the power selector. It seems to delay quite a bit. The alligator clips are also very hard to get plugged into the unit. The plastic on the plug itself feels very cheap and the rubbery plastic on the connectors is poorly finished and looks a bit cheap. It seems to work okay though. The other odd thing is that everything blinks for a while after being turned off.

The adapter for the interior LED kitchen lights went out. I was able to match the 12v 3 amp output from the original. Works perfect!
