Mini UPS, 15000mAh Uninterruptible Power Supply with DC Output USB 5V/2A DC 5V/9V/12V/2A, Power Supply Battery Backup for Router, Modem, Security Camera, Breast Pump, and More (15000mAh)

This mini-UPS is a very cost-effective method to protect my fiber optic modem and wifi router from power glitches and blackouts. Shortly after it arrived we had a lengthy power cut. The wifi operated flawlessly during the blackout and indicated significant battery capacity after powering the equipment continuously for several hours.

I have a cellular router and a power company that isn't super reliable. This is the perfect battery backup to keep my router and phone connected and ride out these small outages that frequently happen. Rather than running a giant UPS system just to keep the internet and phone up (which will beep and scream when off AC power) - the boxes connect right to this battery backup and they run flawlessly and most importantly run silently when the AC power is off. Now when the power goes out (thanks to my laptop battery as well) I can keep working throughout the day with no issue at all. Calls stay connected - internet stays up - and no one knows I just experienced a blink or an outage. Would easily mate up with any router - and I highly recommend you add this to you internet solution.

Someone said that this little unit couldn't power devices if it was charging. It might be true if you exceed what the charger itself (12v / 2.? A) gives the box. It is currently powering a network switch (12v /1 A) and a USB camera (5v / 500mA) right now. Works either plugged in or unplugged/out of power. I wanted this to also power my HDHomeRun box but that one is a center positive and doesn't seem to turn on.

Este producto lo recomiendo 100% gracias a este equipo mi familia se conecta aún sin haber corriente, además que con el equipo también se pueden recargar teléfonos y otros aparatos.

Mine did't last a year. Very disappointed for the price paid.

Ok

Works for about an hour on my wifi mesh, but doesn't power my modem. Returning.

Excelente producto es silencioso su batería es duradera y si hay cortes de luz nunca pierdo la conexión wifi es fácil de colocar
