Monoprice 115877 1 Outlet Portable Mini Power Surge Protector Wall Tap - Black | UL Rated 540 Joules With Grounded And Protected Light Indicator

I wanted a small surge protector for my lanai outlet. This was small enough that I can still close the plastic case that protects the outlet from water. Good buy.

I've bought many Monoprice products for many years, directly from their site and am glad some are appearing on Amazon. Their products are very good and well-priced. This surge protector is being used for a kitchen appliance, where I didn't want a cord being a nuisance on the counter. Been using it for months and so far, so good.

This is a great little surge protector. It will enaure that my garage door opener doesn't fall prey to a power surge like the last one did. Its also small enough that i was able to use the other outlet for something else. Cant ever go wrong with monoprice.

Monoprice 115877 1 Outlet Portable Mini Power Surge ProtectorThis is a good compact surge protector if you can get it at a good price. Per the label (see photo, L to R it's the Belkin, Monoprice, then Tripplite) it's tested/listed per UL1449, the standard for Surge Protective Devices (SPD). The Voltage Protection Ratings are among the best -- I've seen VPR from 400 to 800 V (lower is better), and the Joule rating is decent. Here is how the Monoprice and two other surge suppressors I own rate:Brand _____ #outlets __ PN _____ L-N _ N-G _ L-G __ JoulesMonoprice _1-outlet 115877 ____ 500 _ 500 _ 500 __ 540Tripplite ___3-outlet SK3-0 ______ 500_ 500 _ 400 __ 660Belkin _____1-outlet F9H100-CW _400_ 400 _ 400_ 1080(2021-12-09 reformatted table above so columns hopefully line up after Amazon automatically removes extra spaces)(L-N = Line to Neutral, N-G = Neutral to Ground, etc.)The Belkin has the best specs but usually a higher price. I've bought all three of these when the price dipped to around $6-7, often the price is higher like $9-10. Tripplite has a similar 1 outlet but it's almost the same price as their 3 outlet. The Monoprice came in a nice eco-friendly cardboard box; the Belkin and Tripplite came in nasty plastic packages (update 2022-01-10 added photo of packaging). When plugged into a duplex wall outlet, all three still let you use one other outlet (the Belkin and Monoprice have to plugged into the bottom outlet, the Tripplite has to be plugged into the top).For surge protector I'm more concerned about a good (low) VPR than I am about Joules. Joules indicates how much energy it can absorb before components in the suppressor blow and it no longer protects. It will vary but let's assume a typical surge had 100 Joules of energy in it. Would you like to have a 800 V (bad) 2000 Joule (great) "surge protector" that let 800 Volts through to your TV/microwave/computer/washing machine/etc. 20 times before the protected light goes out? I wouldn't. I'd rather have less voltage hitting the expensive device I'm trying to protect, and when the protector burns/wears out, I'll replace it. BTW I think I've only seen 1 time where the protected light went out in my decades of using them, and I have around 20 of various types (they might wear out faster if you live where there are more frequent lightning strikes).I recommend putting a surge protector on every appliance you have that has an electronic (microprocessor-controlled) control panel. If you have an ancient air conditioner, dishwasher, or microwave with all mechanical controls, you're lucky because it's lasted so long and it's not that vulnerable to surges. But for everyone else, protect your investment with a UL1449 listed Surge Protective Device like this with maximum 500 Volts VPR.The Monoprice doesn't claim to do any RFI/EMI noise filtering, the Tripplite says it does but doesn't state any specs, and the Belkin claims to have up to 43 dB noise reduction from 150kHz to ~100MHz. 43 dB is good, but it's the maximum over that frequency range, so no way of telling how little the noise reduction might be at specific frequencies. Also the Tripplite and Belkin offer limited lifetime warranties and connected equipment warranties but the Monoprice does not. I have no experience trying to make any warranty claim on these.

works fine

IT FITS PERFECTLY ON ONE OUTLET WITHOUT OBSTRUCTING THE OTHER AND LIGHT WEIGHT!

Using this in the attic for a tankless water heater. It would also be great for a microwave or garage opener.

Looks clean with nice lights on it. Have not had any surges that I know of but I do like the design and price of this little unit.
