Wondering how long a portable power station lasts? Learn how to calculate runtime, see real-life examples, and find the perfect ALLPOWERS model for your needs.
🔋 Understanding What “Wh” and “W” Really Mean
When shopping for a portable power station, you’ll often see numbers like 1000Wh or 2000W, but what do they actually mean?
Let’s keep it simple:
-
Wh (Watt-hour) = how much energy your power station can store, think of it as the size of your fuel tank.
-
W (Watt) = how fast your device uses that energy, like how quickly you burn fuel.
So, a higher Wh means a longer runtime, and a higher W rating means it can run more powerful appliances.
⚙️ The Simple Runtime Formula
You can roughly estimate how long your portable power station will last with this formula:
Working Time = Capacity (Wh) × 0.86 ÷ Power of Device (W)
The 0.86 accounts for energy conversion loss (a bit of energy always disappears as heat).
For example:
If your device uses 100W and your power station is 604Wh, then:
→ 604 × 0.86 ÷ 100 = 5.2 hours of runtime.
🔌 Real-Life Power Examples
Here’s how long different ALLPOWERS models can run common UK household devices:
| Device | Power Consumption | Recommended Model | Estimated Runtime |
|---|---|---|---|
| Smartphone | 10W | P100 | ≈ 8-9 full charges |
| Laptop | 60W | P300/R600/S700 | ≈ 4-5 hours |
| Mini Fridge | 100W | S1500/R1500/R1500 LITE | ≈ 8-10 hours |
| CPAP Machine | 65W | S2000 PRO | ≈ 18-19 hours |
| TV (42") | 120W | R2500 | ≈ 12-14 hours |
| Portable Heater | 1500W | R4000 | ≈ 2 hours |
Tip: Always leave a 10–15% safety margin; actual runtime may vary depending on device efficiency and usage pattern.
🌍 What Affects Battery Life
Several factors influence how long your portable power station lasts:
-
Device Power Draw: Higher wattage drains faster.
-
Battery Efficiency: ALLPOWERS R series uses advanced LiFePO₄ cells with 3,500+ cycles.
-
Temperature: Extreme heat or cold can shorten runtime.
-
Usage Pattern: Continuous loads drain faster than intermittent use.
-
Charging Source: Solar charging can extend off-grid use.
