How long will a power station run my home Wi-Fi router?
How long does the router stay up on one charge?
How long the router stays up depends on the adapter watts, the station's watt-hour capacity, and inverter efficiency.
This page uses the BLUETTI Elite 100 mini at 1,004.8 watt-hours and 700 watts continuous, as of October 5, 2026.
The Archer A7 figure is the 18 watt adapter rating, not a measured draw.

A BLUETTI Elite 100 mini at 1,004.8 watt-hours and 85% inverter efficiency runs this TP-Link Archer A7, adapter rating, for about 2.0 days (47.4 hours). As of October 5, 2026.
TP-Link lists the Archer A7 power supply as 12 volts DC at 1.5 amps. That adapter rating is 18 watts, not a measured typical or maximum draw. As of October 5, 2026.
Both of these adapters are 12 volt DC, so a small DC power bank can run many such routers. As of October 5, 2026.
Estimated runtime
Multi-day
2.0 days (47.4 hours)
1,004.8 watt-hours at 85% inverter efficiency is 854.1 watt-hours delivered. This load averages 18 watts. 854.1 divided by 18 is about 47.4 hours.
Assumption: inverter efficiency is 85%.
12 volts times 1.5 amps is 18 watts. That is the adapter rating on the TP-Link page, not a measured typical or maximum draw.
Worked example
TP-Link Archer A7, adapter rating on the BLUETTI Elite 100 mini (1,004.8 watt-hours) at 85% inverter efficiency. Specs in this example are as of October 5, 2026.
| Step | Figure |
|---|---|
| Running watts | 18 watts |
| Duty cycle | 100 percent of the time |
| Average watts | 18 x 1.00 = 18 watts |
| Nameplate volts | 120 volts |
| Delivered watt-hours | 1,004.8 x 0.85 = 854.1 |
| Hours | 854.1 / 18 = about 47.4 |
Result: 2.0 days (47.4 hours).
Assumptions
| Assumption | Value | Note |
|---|---|---|
| Inverter efficiency | 85%, as of October 5, 2026 | The station powers the wall adapters from its AC outlets. |
| Router watts | 18 watts, adapter rating, as of October 5, 2026 | TP-Link Archer A7, 12 volts times 1.5 amps. Not a measured typical or maximum draw. |
| Modem watts | 18 watts, adapter rating, as of October 5, 2026 | Motorola MB8611, 12 volts times 1.5 amps. The combo preset adds it to the router rating. |
| Duty cycle | 100 percent, as of October 5, 2026 | No on-off cycle is published for either adapter rating. |
| Elite 100 mini | 1,004.8 watt-hours, 700 watts, as of October 5, 2026 | 700 watts continuous covers an 18 watt or 36 watt adapter rating. |
Questions
How long will the Elite 100 mini run an Archer A7?
About 2.0 days (47.4 hours) at 85 percent inverter efficiency. The preset is the 18 watt adapter rating, not a measured draw. 1,004.8 watt-hours times 0.85 is 854.1 watt-hours, divided by 18 watts, about 47.4 hours. As of October 5, 2026.
What if the modem is on the same station?
The Motorola MB8611 adapter rating is also 18 watts. Added to the router, that is 36 watts. At the same 85 percent, 1,004.8 watt-hours times 0.85 divided by 36 is about 23.7 hours, 23.7 hours. As of October 5, 2026.
Can a small battery run the router without an inverter?
Both adapters are 12 volt DC, so a small DC power bank can run many such routers. This page does not link a power bank. The hour count here is the AC station powering the wall adapters. As of October 5, 2026.
