Great Purchase

Prompt shipment as always, the pros are it is easy to sit on a desk, or under a desk or mount on the wall. My use is for my laptop and/or my IPads. I can easily take it from office 1 to office 2 to living room, etc. this is a great purchase, I have used APC products since the first day they have been on the market, I can call when I need a battery and most of the time I upgrade, I have NEVER had a bad experience with APC products. The Con on this unit is when you plug in the battery terminals and you sit the unit on a flat surface the yellow terminal sticks out and it wobbles. Since I will move this from one location to the other I will not be mounting it on the wall. It will be sitting on or under a small computer desk or sitting next to where I have my IPads. This is the ONLY problem I am having, I do not like the wobble. It appears that it is either not going into the plug completely or the yellow plus is not flat enough. Other than that it is an A-1 product as always. [This review was collected as part of a promotion.]
It seams to do the job, I have it plugged to my cell phone router, when the power goes out it switches over to battery very fast and I do not lose any signal.
Enough battery power for a mac pro workstation w / dual monitors to do a clean shutdown after a power outage.

Serious entertainment protection

Unboxing is simple, no angry tearing – just pull and slip. The battery connection method is much improved over older models but pay attention to the black arrow as you pull out the plug or you could bend the prongs. Orientation of the outlets invites you to use the screw slots on the back to mount it on the wall. I will use it for my TV and associated equipment, mounted on the wall as I already have a black wall for the TV. There are enough plugs for TV, disc player, air antenna amp. My internet modem is in another location on an older APC. It is nice to have the TV through a storm with a short power outage. Rating is for 2.3 hours – I’ll test it after it has charged. I tested having the TV on after unplugging the unit from the wall – lasted just over an hour then out. Is enough for watching through storms. Anything longer and a generator is called for. I would like to see is a wireless monitoring option but understand that the interface would increase the price. Overall, I have always trusted APC products and this one didn’t change that perception. The size is tailored for average home entertainment and the wall mounting adds a nice option. [This review was collected as part of a promotion.]

Preliminary review

I just received the unit yesterday and have it plugged in charging before I hook it up to any equipment. I will not be using it in my computer as I have a much better unit hooled up there BX1500G.I do have a a big issue with the unit so far. I would like to see a charging status bar (leds) with at least 5 bars to indicate charging status. Your system of having the power button flash different patterns to indicate status would reqiure going to the manual and looking up what certain flashings mean.. If iwas looking to purchase such an item ; I would pay more just for that feature alone. I would like to be able to look down at the unit and know how much charge is left (when power is off) and while it is charging: without going to a manul to decode it. will provide more feedback after I hook it up [This review was collected as part of a promotion.]
I ordered Two of these. Arrived on time and worked following the instructions. 4 stars rather than 5... a lot lighter than I expected.
I had an older moder of APC UPS backup & surge but my battery finally went out. Haven't had this one long enough to say if it is as good but the last one lasted a long time.

Very efficient for small loads

I have purchased more than four of these units, all of them are in service and none have failed. (I am using them with loads < 100 watts) Many of these small UPS units have abysmal on battery efficiency. (Less than 30%) This unit is significantly better than any other I have run the comparison of battery Minute/Watts to delivered Minute/Watts I LOVE that the beeper defaults to OFF. I dislike that there is a hard coded timer that will shut down the UPS regardless of battery at about 2.5 Hours. I ended up buying two of them thinking the first one was defective. I was shocked when they both shut down at exactly the same time with different loads.


I had an old model and this is a huge improvement. SMALLER and lighter than expect. Compact. The negative is that it's too Compact . Hard to plug in a router and modem because the outlets are close.

Compact UPS

Received this UPS free as a product sample. It replaced a large and heavy APC UPS used for my smart TV, DVR and DVD player. A few features that are important to me, as an off-grid homeowner - are the Sensitivity Mode and the adaption to Power Cycling. The latter will likely happen when my backup generator comes on when the solar system (due to days of foul weather) can't provide the household electricity. Haven't had a power failure since setting up this UPS. But I am confident that it will do the job when called upon. [This review was collected as part of a promotion.]
