Frequently Asked Questions
How long will the APC BE700G3 keep my router and modem running?
APC rates the BE700G3 at up to 29 minutes of runtime at a 100W load. A router and modem usually draw much less than 100W, and APC says low-power networking and VOIP gear can run for hours once higher-draw equipment is shut down.
How many outlets does the BE700G3 have, and which ones have battery backup?
It has 6 outlets. Four provide battery backup plus surge protection, and two provide surge protection only. Put your router, modem and other critical devices on the four battery backup outlets.
Can I charge my phone from the APC BE700G3?
Yes. It has a USB-C port and a USB-A port that share a 5V/3A output, so you can charge phones and tablets directly from the UPS.
Can the BE700G3 power a gaming PC?
It is rated at 700VA/420W and designed for home office electronics and networking gear. A gaming PC with a dedicated graphics card can draw more than 420W under load, so this unit is a better fit for routers, modems, VOIP phones and low-power office equipment.
What warranty comes with the APC BE700G3?
Check the manufacturer's terms for claim requirements.
