How Can We Use a Power Bank Correctly to Prevent It From Exploding or Catching Fire Spontaneously?
Power banks are lifesavers for keeping devices charged on the go, but safety risks like explosions or fires can turn convenience into catastrophe. The good news? Most incidents are preventable with smart usage. Here’s your guide to safe power bank practices.
1. Choose Quality Over Price
- Certified Products Only: Look for power banks with UL, CE, or FCC certifications. These ensure basic safety standards for circuits and battery cells.
- Avoid “Too Good to Be True” Deals: Suspiciously cheap power banks often use low-quality lithium-ion cells prone to overheating.
Pro Tip: Check reviews for mentions of “overheating” or “swelling.” If unsure, consult CNS Battery’s safety-certified power banks for reliable options.
2. Handle Charging with Care
- Avoid Overcharging: Unplug once devices reach 100%. Most modern power banks stop automatically, but older models may not.
- Use Original Cables: Cheap, frayed cables can cause electrical shorts during charging.
3. Monitor Temperature & Environment
- Keep It Cool: Avoid leaving power banks in direct sunlight, cars, or pockets during exercise. High temps degrade battery health and increase fire risks.
- Don’t Cover While Charging: Ensure airflow around the device. Overheating is a key warning sign of impending failure.
4. Avoid Physical Damage
- Protect From Drops/Water: Cracked casings expose internal circuits to moisture and debris. Use a protective sleeve during travel.
- No DIY Repairs: Punctured or swollen batteries are hazmat risks. Dispose of damaged power banks at certified e-waste centers.
5. Store Properly When Not in Use
- Partial Charge: Store at 40-50% capacity in a cool, dry place. Fully charged batteries degrade faster.
- Avoid Metal Contact: Store in non-conductive containers to prevent accidental shorting.
Urgent Warning: If your power bank swells, emits smoke, or feels hot to the touch, stop using it immediately and contact Amy at CNS Battery for safe disposal guidance.
6. Travel Smart
- Airline Rules: Carry power banks in carry-on bags (max 100Wh for most airlines). Never check them in.
- Use Surge Protectors: In hotels, plug into outlets with built-in surge protection to avoid voltage spikes.
