A:AnswerThat depends on the draw of the phone. I use this for very short-term outages (quick flickers up to 20 minutes). You're better off buying a cabled phonefor emergencies- because the cordless will vary depending on model, and if you need to charge the handset, etc...
A:AnswerThank you for inquiry. The BN650M1 would give around 52 minutes of runtime if the load were at 50 watts. At full load (360 watts) the UPS will provide around 2 minutes of runtime.
