Quick checklist
- Inspect the housing, ports and included cable.
- Keep the power bank cool, dry and protected from impact.
- Stop using a swollen, leaking or abnormally hot unit.
Condition matters before capacity
Do not buy or continue using a power bank with swelling, cracks, damaged ports, liquid exposure or burn marks. Ask for the exact model, rated capacity, input and output information, included accessories and product-specific warranty.
Charging the power bank
Use an input method listed for the exact model. Place the unit on a stable ventilated surface and disconnect it if you notice unusual heat, smell, sound or deformation.
Carrying and storage
Protect ports from metal objects and avoid pressure from heavy items. For air travel, check the current airline and aviation rules for spare lithium batteries before leaving Kabul.
Capacity and output claims
Printed cell capacity is not the same as energy delivered to a phone because conversion losses occur. Confirm the rated specifications and avoid unrealistic promises about recharge counts.
Frequently asked questions
Can I use a swollen power bank?
No. Stop using it, keep it away from heat and seek appropriate local disposal guidance.
Why does a power bank feel warm?
Some warmth can occur, but abnormal heat or deformation is a reason to disconnect and inspect it.
Is the printed capacity the exact amount delivered?
No. Voltage conversion and charging losses reduce usable delivered energy.
