Some Main Reasons for Power Bank Malfunction

A power bank is essential in the office or during power outages. Lithium-ion batteries are sensitive. Avoid heat, cheap cables, getting it wet, and frequent full charge-discharge cycles. Extend its lifespan with proper use.

Method

Leaving it in the sun or heat

Leaving a power bank in direct sunlight or a hot place causes its battery to degrade rapidly. High temperatures damage the electrolyte, weaken the electrodes, and can cause the battery to swell. A temperature of 20-25 degrees Celsius is optimal.

Leaving it plugged in

Leaving a power bank plugged in for extended periods after it's fully charged puts stress on the battery. Trickle charging reduces its capacity. Unplug it despite safety features. Remove it immediately after charging is complete.

Using cheap cables

Cheap cables lack voltage control, temperature monitoring, and overcurrent protection, leading to circuit overload, short circuits, and overheating. Always use UL/CE certified branded charger cables.

Completely draining the battery

Draining the battery to 0% reduces its lifespan, decreases the number of charging cycles, and accelerates discharge. Recharge when 20-30% of the charge remains.

Using and charging simultaneously

Connecting a device to the power bank while it's charging puts a strain on the control board. Heat increases, and cheaper models can malfunction. Charge it first, then use it.

Damage or water contact

Protect it from shocks or drops to prevent damage to the battery's internal layers. This can cause a short circuit or swelling of the battery. Water contact is even more dangerous. It can cause corrosion and lead to thermal runaway (risk of fire). Most power banks are not waterproof.
