Keep your internet and home Wi-Fi Network online during prolonged power outages.
Backup Power for more than 5.5 hours
Device List:
| Function | Device | Model | Volt | Rating | W |
| Vumatel CPE/ONT | Raycore | RC-CP9SZ-NNN2-SMNQ | 12V | 1.0A | 12 |
| ISP Router | Zyxel | EMG3525-T50B | 12V | 1.5A | 18 |
| Wi-Fi AP | Ubiquiti | Unifi UAP-LR | 24V | 0.5A | 12 |
Total Wh = (12+18+12) = 42
- Internal & ISP router connected to 12V port.
- Ubiquity AP connected on passive 24V PoE port
Theoretical backup time for Power-Buddie DC UPS 75Wh = 107 Minutes
This is calculated (UPS Wh (75) \ Total device Wh (42)) * 60 minutes
For the above mentioned scenario, the Power Buddie DC UPS 75Wh (24000 mAh) provided backup power for 339 minutes.
In comparison, a generally available 8800 mAh DC UPS provided backup power for 110 minutes.
Why does it appear that the UPSes are performing far better than what they are rated for? Most devices, although not always the case, use substantially less Watts than their maximum rating. Hence why it seems that the UPSes are performing better than expected. The theoretical maximum of 42W were never observed, the UPS reached a maximum of 13W and averaged on between 10 and 11W.
