Works
Solid UPS, the USB ports give enough power to charge most phones that we don't want users connecting to laptops. Enough power to keep everything up including multiple monitors until generator power comes on-line.

Perfect UPS for my home computer setup
I selected this UPS for my home laptop, docking station and 2 large monitors. The UPS was tested with my setup and it was rated to last 60+ minutes. Not bad.
My home networking equipment is already protected with this same exact UPS. It was tested to last 45 minutes on my networking devices: router, wifi, fiber, Ooma and various IoT devices.

Good UPS at a good price
I've purchased and used various APC UPS products at my home for about 20 years. They have always worked well, and I've never lost any equipment or data to power line problems. I love the form factor of this particular UPS because it fits nicely into a bracket attached to the underside of my wooden desk which helps keep the various power cords organized and off the floor. I also love the 9 outlets which I absolutely require. The companion Power Chute software also works well. I bought this new unit to replace one that had failed after 4 1/2 years of faithful service (UPS broke but the battery was still good). I gave this product only 4 of 5 stars because in my opinion a UPS should last about 3 to 4 three times as long as the lifespan of the internal battery which is about 2 years per battery. So, the UPS should last about 6 to 8 years, not 4 1/2 years as did my previous model. Hopefully, APC addressed any shortcomings in the previous models with this updated model. On the whole, I completely recommend this UPS and APC UPS products in general.

I have this installed for a PC with three monitors at a home office. The power provided is more than enough if there's an outage and the added USB charging ports are a huge bonus too. Lots of protection with the 6 power back up outlets and the extra 3 surge protection outlets and USB's.

So Many Plugs!
I continue to appreciate APC's BackUPs equipment to protect my electronics. However, some one missed the proverbial boat some where along the way. Each of my devices designed with with a plug-end power transformer is oriented 90 degrees out of alignment with the UPC's plugs. It's still necessary to use outlet expanders to get every thing plugged in. Thank goodness for the 9 available sockets on this UPS!

Surprising features
I found the Back-UPS 850VA, 2 USB charging ports to be a surprising product. I expected good clean power and a good UPS, since this APC’s strength. I was pleasantly surprised by the connectivity provides for devices. There are 6 UPS protected sockets, two of which are space so that small direct plug-in power supplies can be plugged. In addition, there are three surge protected sockets. This is more than enough connectivity to service the system that would be plugged into a small UPS. I think this unit has more electrical sockets than some of my larger UPS units. In testing the UPS ability, the performed well and easily handled the system I had connected. Overall, I am very impressed with this unit and would give in a 5 star rating.

Slender design
It is a fair price for a low-end backup product. It also has a slender design that can fit in under a table or back against the wall. it has a good amount of charging ports and I also like that I can plug my phone in just using the cable and not the adapter. Only complaint is it a little bit noisy.

Small package with great power
I received this unit a few days ago, and had the chance to plug it and test it with my equipment. It is very quiet, and compact for a Backups 850Va unit. It is actually a quite nice design. The unit comes with a USB A to B cable for the use of Powerchute power management software (to plug from a computer or other device with a usb port, into the back of the APC unit). There is a full instruction book printed on paper. The performance is great keeping my equipment going for several hours with power off.
I have three minor quibbles.
1) This is using the older APC design where you have to hook up the wires to the battery. The newer designs internally have a battery pack that just slides into place which would be preferred.
2) The red power wire to hook up to the battery is a bit short and it took about a minute of stretching the wire and maneuvering the battery pack in order to get the wire hooked up. The wire could be a bit longer.
3) There is no LCD read out panel. This would have been a nice add on, but might have compromised the ability to deliver this amount of backup power in such a small package. Low battery is indicated by the power button showing a flashing green light instead of steady so, it really covers that base.
These minor quibbles do not affect the functionality of the unit or its performance, and I would be willing to buy this unit the next time I need a battery back up unit.

Excellent Back up for electronics
I received this unit for review. This makes the third Back-UPS 850 unit that I have. I purchased two earlier versions. They are consistently easy to use and protect from power outages. I live where weather related outages are common so having protection for our video equipment and computers is very important. All units have worked very well though the two attached to our desktop computers also need to have the proper PowerChute software loaded to allow them to do a controlled shut down after surges or power loss. There are six (6 plugs with battery and surge protection and three (3) with surge only protection. The new units have two (2) USB ports that are also protected. Other than for computers, the units are simple to plug and work immediately to protect audio and video equipment.

Excellent Size for Above or Below Desk
The APC Back-Ups 850 is very reliable and easy to install. Connected the battery, plugged all my devices in and all protected. I unplugged the APC and their was not even a glitch of failed response from the devices. Never missed a second of power to the computer or monitors. APC has created a very effective personal Back-Ups device that can be moved easily and quickly to other location and provides more than enough run time to ensure devices can be turned off. Very satisfied with this new APC.

What I really like about it is the 2 USB ports that will come in very handy with any hurricanes that form along the coastline, the battery side of 110 volt outlets you can actually plug in a small LED reading lamp with on off switch, these are more then just for computer use they are also good for emergency

Good but could be better
The 850 VA UPS has good staying power but would be much more useful if the power outlets were oriented 90 degrees so the the spades of the receptacles were parallel to the long dimension instead of at right angles to it. Many devices today come with wall wart power supplies, routers , switches, printers etc and the way the outlets are oriented now they tend to block other outlets.

This is a nice unit that I use for my Harman P68 wood pellet stove. If my power goes out I will have about 15 minutes to turn off my stove so the house doesn't fill with smoke and ash as what would normally happen. To me this was worth the money to have that kind of protection.
