It works well. but only for about 2 years.Pc & hub

Good product. Works for its purpose.

I got this to power my QNAP NAS in case the power goes out. From best to worst- it looks quite nice and as a unit for sitting under a tv, doesn't stand out but the light is a little bright.- USB support is excellent and doesn't need anything special to work out of the box. the qnap saw it straight away and started using it plus my windows pc saw the battery as soon as i plugged it in and started acting like a laptop, which is excellent and allows you some very special power management based on percent of charge and if the power goes off.- When the power goes out, while it isn't full sine, it's not quite as aggressive as some of the other units i've used. you can still hear that it's not full sine but it doesn't sound like it's wringing the neck of the devices connected to it.- Run time is acceptable, i've gotten 10 minutes out of it with more to spare (with about 200w load) and for my use that's all i need, i can't comment on full run time but as this unit uses lead acid batteries i wouldn't ever recommend running them completely flat as that will damage them.- This unit does run quite warm, the AVR circutry seems to give off a fair bit of heat so if you're putting it in a cupboard make sure that there's a fan blowing some air over the unit, i don't think i'd like to see what would happen if the lead acid batteries start boiling.and the worst- You can't change the batteries yourself, i'm sure you can order the replacements but the actual unit is designed in such a way that it's not trivial to replace the batteries, which in my eyes is just stupid. for something that will last max 3 years, that's a poor move from APC and doesn't inspire confidence. for me that's not a big thing as i will be upgrading to another full sine unit in the future but that still leaves a bad taste in my mouth. i wish i knew this before i brought the unit because it's just as important to be able to service the unit as is the quality of how it works.Overall, you'll be well served by the unit for low priority stuff and the USB support is excellent, just a shame about the batteries.

I purchased this UPS to connect to my small office server which runs 24/7. Living in a village means we are occasionally subjected to short power disconnections. A Server running 24/7 with CCTV writing to the HDD requires a stable power connection so that your HDD are not damaged by such power cuts. I didn't require anything to heavy in terms of a UPS as our power is normally restored pretty quickly. I just wanted something that would connect to my server via USB and initiate the self protection mode for the disks - the BX750MI would provide this protection for me so i placed my order.First impressions were that the UPS is fairly large. For a single 9ah battery i expected it to be a little smaller. Inside the box you get the main UPS unit and an IEC male to female kettle connection lead. Whilst this is great for built in PSU's it was of no use to me as my device using a barrel plug connection. I solved this by connecting an IEC extension lead to allow me 3 pin UK plug connections. What was super frustrating is that the package did not include a power connection cable!! How can a company sell a product that you can not even use out of the box! I didn't have a spare IEC 3 pin power lead, so this meant i had to go out and buy one to connect the device to the main power. I can not being to tell you how frustrated this made me feel!After i purchased the power lead (yes i am still super annoyed by this!) the device sprung to life. The device is very simple, providing a minimal amount of backup power for lower powered device, up to around 300W. My server uses around 45w so this was more than ample. There is no display on the UPS so you have no idea of your remaining run time load, however my QNAP recognised the device straight away when connected with the included USB cable and informed me i had around 45mins of power.There are two strips of very bright green LED's on the device which illuminate the whole room at night. You can dim these slightly by holding the power button, but they are still way to bright for my liking. You can not disable them whatsoever. Testing the UPS function worked well, it continued to power my server until reconnected to the mains supply. What was annoying was the loud buzzing that came from the unit when it was supplying power to my server. I have another UPS in my lounge and this is absolutely silent apart from the intermittent beep it makes to alert you to the power failure. The buzzing from this APC unit made me question if the device was functioning correctly and if it was safe!I also tested the load on the device after the internal batteries were charged to 100%. The UPS has an overhead of around 15w according to my energy meter. So it will increase your energy costs by connecting up this UPS, however it should only be by around a small amount. My understanding of this device is that is also uses a stepped sinewave rather than a pure one - that should be fine for most home usage scenarios, but if you have highly sensitive equipment, especially with motors connected, then you should consider spending a little more to obtain a pure sinewave UPS.Would i recommend this UPS to others? If it came with a power lead then i most probably would, it's not badly priced, and does do the job of maintaining power during a power cut. The bright LED's i can kind of live with, the buzzing noise is frustrating, but this only happens when it switches to battery power mode. I just can not get past the fact they do not include a power lead with the device! Based on this i just can not recommend this device to others! A kettle lead literally would cost this company a few pence - it's just bizarre to sell a product you can not power straight from the box?!My advice is look elsewhere...I hope that you found my review helpful

Pro’s:- price- brand is well known- simple and easy to installCon’s:- stinks for weeks (kind of an electronic smell)- no LAN Port- can’t think of anything elseI bought this simply cause around Harrogate we had a few power cuts and it did annoy me that my openhab crashed every time, so this is the solution, all the “smart home” stuff now is powered via UPS, tested it for 20min lost 18% battery so i am sure it would last about 1hr.Very please with it!
