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)

Works great just what I needed for my Fiber Modem + TP-Link Deco Mesh

It works for around 12 hours, which is good in a blackout

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.

I have two routers plugged into the UPS, unplugged the UPS for 5 minutes and to my surprise it only went down one light! I would believe that it would last 20 minutes without power.I would recommend this!

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.

Ya está instalado duro tre hora sin problema.. aún seguía con mucha carga

This is a rechargeable battery, not a UPS. You cannot is leave it plugged into the wall and plugg d into the device you wish to power.

Es la mejor compra que he hecho, en mi país hay constantes apagones y esto me viene de maravilla para siempre tener internet y además tener conectada una cámara de vigilancia, la batería es suficiente para soportar eso y más, estoy muy contento con mi compra, recomiendo por completo este producto
