54v Power Adapter 210w, 54V Power Supply for UniFi XG 6 PoE, USW-Ultra Switches, 3.9A Output

You Save Money and It Doesn’t Seem to Cut Corners Like Others
What You Should Know: This is the budget option and it works fine. If and when it breaks, I’ll update this review so if you don’t see an update, assume that it’s still working just fine. From my testing, I didn’t see any anomalies with heat, electric coil noise or efficiency. However, it was slightly lighter than I expected a 210w power supply to be so I’ll keep my eye on it and see how it does over time.____________________________________________The Good: It’s no frills but it includes two additional tips to compensate for the slight variations in contact sizes between PoE switches allowing this power supply to have a broader compatibility than others.For context, the model number of the unit I got was: JYH23Z-5400390-BYPrice Breakdown Compared to Others:At the time of this writing, this 210W power adapter is priced at $89.There was another seller on Amazon selling what appears to be the exact same power adapter for 10% less after coupon however this model had bad reviews on it because the barrel connector didn’t snugly fit the Unifi devices it was advertised for and unlike this product, it didn’t come with additional tips. Essentially, the product I’m reviewing has the additional tips included for an extra 10%.For the extreme budget friendly version of this, I found an “open box” one of this exact model with extra tips on [redacted]Bay for 50% less with “free returns”. Although typing that whole previous line caused the hair to stand up on the back of my neck as I wouldn’t suggest that you actually buy one off of [redacted]Bay, I wanted to build some context.UI-dot-com’s 210W (UACC-Adapter-AC-210W) at the time of this writing is priced at 10% more after taxes and shipping. It comes in all white with a wall bracket, screws, and whatever warranty (if any) that UI-dot-com will offer along with it. It’s guaranteed compatible with the Unifi devices it’s designed for and it has a right-angle connector compared to the straight one in this review.To sum up:[redacted]Bay Used/Open Box: 50% priceOther Seller: 90% priceThis Seller: 100% price ($89 currently)UI-dot-com: 110% priceIf you are already purchasing something else from UI-dot-com and you can combine the shipping cost or you want the wall bracket that comes with an official power supply, it might be a better to buy the officially supported power supply but if you aren’t buying anything soon and want broader compatibility, this seems like the best choice to me.

Solid replacement power supply for UniFi PoE gear
Needed a replacement power supply for my Ubiquiti UniFi PoE switches after the old one gave out. Not much to say, plug it in and it works perfectly. The output shows a steady 53.5V, and it stays cool to the touch even after hours of operation.Simple, reliable, and does exactly what it’s supposed to.

Good alternative for Ubiquiti switches.
Works great on my Unifi switch, very small for the amount of power it delivers. A little on the pricey side but it is very well built and if you need a power adapter quick and can’t wait for ground shipping, this is a good alternative.

Extremely durable power supply
Worked absolutely perfectly for my unifi system. My original cord finally burned out after a power surge. Luckily my equipment was OK and just the cord went bad. I decided to give this a try and I’m glad I did. It works absolutely flawlessly maintains everything. The wattage is correct. The voltage is correct. It works exactly how it’s intended to. The build quality is excellent. It is heavy duty. It seems extremely durable and it doesn’t get screaming hot like some of these cords get. Overall, I am extremely pleased with this.
