Most power banks die long before they should — and it's almost always the user's habits, not bad luck. Here's what the battery science actually says.
1. Don't wait for 0%
Lithium-ion cells hate full discharges. Recharge when the indicator shows one LED left (roughly 20–30%). ASUS's official battery FAQ puts a normal Li-ion lifespan at 300–500 full cycles before capacity drops to 80%.
2. Don't store it empty
A power bank left at zero for months can deep-discharge below the safe voltage and die permanently. Storing it? Charge to ~50% and check every few months.
3. Keep it cool
Heat is the number one battery killer. A car dashboard under the sun can degrade a battery up to 60% faster. Keep it shaded and ventilated.
4. Unplug after full
Modern power banks cut current automatically, so classic overcharging is rare. But sitting at 100% for hours still accelerates degradation — unplug when full, especially overnight.
5. Use quality cables and chargers
Cheap cables create unstable current and heat. Use the included cable or a trusted brand, and a charger matching the power bank's specs.
6. Don't use it as a daily charger
It's an emergency device. Daily full cycles burn through the 300–500 cycle budget fast: a full cycle every day means ~1.2 years to 80% capacity; every 2–3 days stretches that to 2–3+ years.
7. Buy a decent one in the first place
No amount of care saves fake-capacity cells. Pick a reputable brand with real protection circuits.
When to replace it
A swollen body, weird chemical smell, or wildly jumping LED indicators mean it's done — don't keep using a swollen battery.
