The BGE50ML is a unique UPS and mobile battery pack combo. As a UPS, it takes care of small networking equipment like modems or wireless routers during power outages. As a battery pack, you can use it either as a USB desktop charging station, or you can undock it and use as a 7200 mAh portable charger for your mobile devices. Though versatile, it is also very costly and more expensive than simply buying a UPS and a power bank separately.

Pros
Pro Can be used as a mobile power bank
Designed to be an on-the-desk UPS, you can undock the battery pack easily when going on trips, then dock it back for charging once you get home. Keep in mind that taking the battery out of the device will turn the UPS into a simple surge protector, leaving your equipment vulnerable to power outages.
Pro Remarkably long on-battery life of 33 minutes at full load
Unlike other UPS units, this one has an unusually long on-battery life of 33.2 minutes at its maximum load. In the event of a blackout, you can still power your modem/router and access the internet for 30 more minutes using other devices like mobile phones and laptops.
