    Sufficient amount of backup for the devices I have plugged in. Holds my cable modem, IP phone and router up for 10 minutes in between brief power outages.

    Has worked just fine thus far. It's small and so it doesn't last all that long when the power goes out, but it's adequate.

    This item is the real deal. I bought two so I could still have power to my PC and TV/Internet when power goes out. I have a generator that comes on but there is a small gap between the two so everything goes out. Last outage, I was not home but when I got home I realized power went out but my PC was still running, no interruptions. Great product.

    Power went out in a storm and the backup kept my WiFi up for phones and also provided light with the lamp connected to it.

    The Fix for Transient Power Drops

    We live in Florida and experience many brief power interruptions. They might last 1/2 a second to 5-10 seconds. But when you are watching TV, the cable box drops and it takes minutes to reboot. This little device was the answer to that challenge. It's already held the TV and cable box up and running during a series of minor blips in power. Nice little device!

    Use this Battery Back to plug our TV, wifi modem, satellite electronics, etc. into. We have a generator, but there is mementary outage before it kicks in. This saves me from having to reset wifi, printer, etc. Don't need it to run for any length of time, so it is perfect. Good price. Hope it lasts longer than the previous one I had that lasted just over a year.

    Great product. I buy them frequently for my work and they haven't let me down yet. Has plenty of space to plug in multiple items. I like how some of the outlets dont use the battery so when power is lost only the necessary things are draining the battery.

    Nice compact design for areas where you only need a basic UPS. Like fact that battery is replaceable rather than having to purchase entire unit. Using for Desktop PC and monitor where we have occasional flickers in power and this does the job to keep everything going. Have lost power once since purchase and this unit gave ample time to do a safe shutdown of Windows 10 PC to prevent any loss of data from documents was working on.
