The APC UPS Battery Backup Bundle includes two models - the BE900G3 with 900VA / 540W capacity and the BE500G3 with 500VA / 300W capacity. Both models provide battery backup power and surge protection to keep your devices running and safe during outages. The higher-capacity BE900G3 has 8 total outlets - 6 battery backup outlets to keep devices powered plus 2 surge-only outlets. It also features user-replaceable batteries, allowing you to swap in new batteries when needed to extend runtime. With ample power capacity, it can keep even high-power devices like multiple PCs and AV equipment running long enough for safe shutdowns before switching to low-power networking gear, maintaining internet access for hours. The BE500G3 has 6 total outlets with 4 providing battery backup power. It shares convenient features with its larger sibling like automatic voltage regulation, USB-C and USB-A charging ports, and replaceable batteries. Its compact 500VA capacity focuses on powering essential devices like routers, modems, or an internet phone to keep you connected. With both small and large power protection needs covered, this APC UPS bundle is ideal for home and small business use. The pair work in tandem - powering critical gear through short disruptions with the BE500G3 while the BE900G3 keeps high-power devices operational long enough to prevent data loss.
