Time will Tell.this unit will protect your delicate devices from spikes in your electronic devices, it will proect from brown outs (power going down will also damage) spikes from a shorting out from a pump, cord being cut and twisted.

For me, this device is unusable for its intended purpose.

I bought this not for protecting sensitive electronic devices but to provide quick-response uninterrupted power to a 120V, 2A wall-mounted LP gas water heater.

The device lasted 24 hours before my house was filled with a piercing wail as the ups died.

I've been surprised at how often my house power briefly drops below the preset "trigger level" (intermittent brownouts) and this little device takes up the slack.

If all your expensive electronic devices are not on a UPS you are just WRONG.

A flawless device!!

It will not rapid-charge, but it does work well for slow-charging devices

These devices are useful for maybe providing a power backup to your router, modem, and printer, but it can't seem to handle anything actually worth using a battery backup for

I then put my 3 critical devices into "surge only" plugs, installed the APC software and powered it on again.

Gave it a test, and it sufficiently supported the devices I had

I love this device

Rather than protecting connected devices, it is CREATING power outages for the protected equipment.

The device is made well – set it up in less than 2 minutes.

So if you want a reliable high pitch alarm device, this should be your first choice

Its a great device and will protect your SSD from blanking itself if the power suddenly goes

I can unplug the power from the UPS and devices (a small computer and a switch) continue to work uninteruppted, however when the power goes out my devices get into this weird "running but not working state"

I tried Cyberpower and LiteOn and returned both after finding they did not allow voltage adjustment other than the factory setting of 90 volts and something like 140v, All current electronic devices stop working at 100 volts (lots go all the way to 220v on the high though).So with this

Outlets are too close together and can't be fully utilized if you're using devices like TP-Link's AC1200 as the wall wart runs left to right (vs. down from the outlet)

Works fine to protect 120V line-powered devices.

once connected, I set the unit up and plugged devices in and all worked well from the get-go

This device works as advertised

I have internet phone service as well as wifi and this device is well appreciated.

The battery is expensive and doesn't last and the device goes into alarm mode and refuses to shut off

They are awesome backup devices.
