This is very old technology, and is heavy and bulky, but works and is inexpensive. "

"Ports on the front of the device allow you to plug in and charge other devices, though I don’t think I’d need to do that very often. These batteries aren’t the lithium cell styles you’re used to, their workhorse lead-acid batteries - reliable, heavy, but usually left stationary. ...However, there was a noticeable ozone smell, which I attributed to the lead-acid battery's first usage. The battery life met my expectations, although the recharge time was quite slow, taking most of a day. "

"It's a 'square wave' UPS and with a typical sealed lead-acid battery. 'Square Wave' UPS are simpler as it doesn't recreate the Sine Wave of AC current. ...Perfect for Small Jobs...It is suitable for lower wattage PCs also, like an all-in-one or mini box."

"This UPS is just a bit more powerful than the 625 VA models I've used and very little more in cost. The internal battery is a single lead acid type battery, easily replaced when necessary, down the road....Because they are not overpriced, and have the features I'm looking for. Plus, their batteries are super easy to replace when needed. Though I will update my review to 6 stars when they start using LiFePO batteries instead of old-school lead acid."

"great back-up battery for a great price...I got this one on sale for $45. It's the smallest unit I have seen. It powers my computer, lamp, monitor, and my Google Mini. ...Great for small home office set up! (Mac Mini)...It's worth it at the price and is perfect for a small office setup."

Does the job for the company....great for mac mini & mini pcs...cyberpower is a very good brand. ideal for a mac mini or mini pc, and display.i replaced my 1500va cyberpower, that went out after 9 years, with this compact unit. only wish they would add a small lcd to show remaining power. overall a good buy."

"Simple setup, you do have to remove the plastic barrier so internal lead acid battery can charge. I use it to protect my desktop computer, wireless router, cable modem, and digital TV from fluctuating power which has become more common at my home. ...Recycling lead-acid batteries is a pain...You have to replace the battery every 3 to 5 years and it is hard to find a place to recycle the old lead-acid batteries.
