Device list:
| Function | Device | Model | Volt | Rating | Wh |
| Internet Router | Ubiquiti EdgeRouterX (5P) | ER-X | 12V | 0.5A | 6 |
| ISP Router | Huawei EchoLife | G8240H | 12V | 1.0A | 12 |
| 8 Port Switch | Netgear ProSAFE | GS110TP | 48V | 1.25A | 60 |

Total Wh = (6+12+60+9) = 87
- Internal & ISP router connected to 12V port.
- 8 Port switch connected to 48V port.
- 1 Port on the switch is powering the PoE AP.
- 5 Ports on the switch are being utilized without PoE.
Theoretical backup time for Power Buddie DC UPS 75Wh = 51.72 minutes
This is calculated (UPS Wh (75) \ Total device Wh (87) * 60 minutes)
For the above mentioned scenario, the Power Buddie DC UPS 75Wh (24000 mAh) provided backup power for 279 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.
