Customers are saying

Customers frequently mention the 750VA Battery Back-Up System's great size, reliable battery life, and overall performance. Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    After initial charging the unit was ready to protect my electronics. Liked that the unit provides surge protection as well as battery backup.

    Performs as "advertised". Upgraded my Office system, and realized the "old" unit wasn't handling surges well. Excellent software and easy to set-up and "forget"

    Solid design, not the best USB charging

    Works as advertised: keeps the power going even with an outage. USB ports seem to work when they want to, with inconsistent charging power.

    Got this just for my ONT, gateway, and router. I have AT&T fiber internet which requires an indoor optical network terminator as well a gateway device. I use my own router (Asus RT-AC86U) and while powering all 3 devices with a load on them I can get roughly 30 minutes of backup time. More than sufficient for a short brown out or black out scenario. I don't have it connected to a PC or anything at this point, but I have tested it's capabilities by throwing a breaker and it works great. The only thing I would like to have seen is true sine instead of simulated sine. But it was cheap so I can't complain!

    Very happy with this device. Easy to hookup obviously. And yes, I did have some nasty storms come through and it did trigger the UPS. THANK YOU! No blips no hits ... Great. It's a winner!

    I have my router and modem plugged into this so if we take a power hit, before my stand by generator kicks in, this prevents an outage of the internet

    Have this plugged into our AV closet for backup power for our modem, switch and Orbi Mesh system. Switches on if we ever lose power and my wife can keep working from home. Small and quiet.

    I bought this for my desk on wheels so I can move it around the house (don't ask why). Let me tell you a funny very short story. I was planning to clean my room with a vacumm and I plug it into a extension cable, unknowingly the cable being plugged into the battery. I turn it on and I killed my battery within 3 seconds of use. The battery survived just had to recharge it. 10/10 Would do it again accidently.
