How long does a 8800mAh battery last on router?
The runtime of an 8800mAh battery on a router depends on the device’s power consumption, which typically ranges between 5W (low-end models) and 20W (high-performance or dual-band units). For example, a 12V router drawing 10W would deplete an 8800mAh battery in approximately 10.5 hours (88Ah × 12V ÷ 10W). However, actual usage varies with network load, signal strength, and connected devices. Pro Tip: Use energy-saving modes like scheduled Wi-Fi to extend runtime by 15–30%.
How do router specifications affect battery life?
Wi-Fi standards and antenna count directly impact power draw. Dual-band routers (2.4GHz/5GHz) consume 30–50% more energy than single-band models. High-gain antennas (5dBi+) increase transmission efficiency but raise consumption by 5–8W. For instance, an 8800mAh battery lasts 18 hours on a 5W 2.4GHz router versus 9 hours on a 10W 5GHz model. Always check the router’s rated voltage (9V/12V/19V) to match battery output.
What environmental factors reduce battery runtime?
Temperature extremes and signal obstructions degrade efficiency. In cold environments (＜5°C), lithium batteries lose 20–30% capacity temporarily. Thick walls or metal barriers force routers to boost transmission power by 15–25%, accelerating drain. A typical 8800mAh backup might last 12 hours at 25°C but only 8 hours at 0°C. Pro Tip: Position routers centrally to minimize signal boost demands and avoid heat sources like radiators.

FAQs
Only if they support continuous 9V/12V DC output—most USB power banks lack stable voltage regulation for routers. Use UPS-grade batteries instead.
How to calculate exact runtime?
Multiply battery watt-hours (Ah × V) by router efficiency (usually 85–90%), then divide by router’s max wattage. Example: (8.8Ah × 12V × 0.85) ÷ 15W ≈ 6 hours.
