The 100W Power-Buddie with 165Wh (52000mAh) LiFePO4 batteries are the ultimate high-end DC UPS. It provides a wide range of voltages and ports to cater for most home automation and POE DC needs. The UPS can even power a *54V DC POE switch via the 48V DC port. In this case study the Power-Buddie UPS powered a Home Assistant automation system for more than 5 hours. The maximum combined Wh rating of the devices were 118W (Actual usage ranged between 22 and 27W).
Power 118W for 320 minuets (Actual usage 22 - 27W):
Device list:
| Function | Device | Model | Volt | Rating | Wh |
| Home Automation | Intel NUC | DCCP847DYE | 19V | 3.4A | 64 |
| Edge Router | Ubiquiti EdgeRouter | ER-X | 12V | 0.5A | 6 |
| LTE Backup Router | Huawei | B331B-853 | 12V | 1.0A | 12 |
| Network Switch | TP-Link LiteWave | LS1008G | 5V | 0.6A | 3 |
| Fibre Router | Huawei EchoLife | HG8240H | 12V | 1.0A | 12 |
| Wireless AP | Ubiquiti AP AC Pro | UAP-AC-Pro | 48V | 0.5A | 9 |
| IOT Bridge | Sonoff RF Bridge | RF Bridge | 5V | 1.0A | 12 |
Manufacturer provided maximum Wh = 118Wh (Actual consumed 22 – 27Wh)
Configuration:
- Fibre, LTE and Edge router connected via 3 port splitter cable (12V DC port)
- AP connected to 48V POE port.
- NUC connected to 24V POE port (Stepdown board used to reduce to 19V)
- Switch connected to 5V DC port.
- IOT bridge connected to USB port (5V)
Theoretically the UPS should not have been able to power all the devices. However, due to manufactures over stating power requirements the Power-Buddie was able to start with all the devices connected (Max Watt consumed during startup = 42W) and provide power for 320 minuets
How does the 165Wh Power-Buddie compare to other tests we have done:**
- Normal 2kva UPS provides 84 minutes of backup power.
- Power-Buddie 75Wh provides 140 minutes of backup power.
- Power-Buddies 165Wh provides 320 minutes of backup power.
* Devices powered by the 54V POE switch must have a voltage required lower than 48V
