Wireless Charging Safety Checklist

Wireless Charging Safety Checklist

Use this checklist to ensure your wireless charging setup is safe and optimised.

Charger Selection

• [ ] Use Qi or Qi2 certified chargers — Look for the Qi or Qi2 logo on packaging. Certified products have passed safety testing.
• [ ] Avoid unknown-brand chargers — Generic chargers without certification may lack overcharge protection, voltage regulation, and thermal safety.
• [ ] Inspect before use — Check for cracked casing, frayed cables, or signs of heat damage. Discard damaged chargers.
• [ ] Match the power adapter — Use a USB-C PD adapter rated 25W or higher for 15W wireless chargers. Undersized adapters cause stress on both components.

Placement Safety

• [ ] Never place under bedding — Pillows, blankets, and mattresses restrict airflow and trap heat. This is a fire hazard and a significant battery damage risk.
• [ ] Charge on hard, flat surfaces — Nightstands, desks, and counters provide good ventilation. Avoid soft or flammable surfaces.
• [ ] Ensure airflow around the charger — Do not place against a wall with no gap or stack items on top.
• [ ] Keep away from liquids — Spills on a charging pad can cause electrical hazards. Keep liquids at a distance.
• [ ] Check for metal objects — Remove coins, keys, and metal cards from near the pad before charging.

Overnight Charging

• [ ] Enable battery protection mode — Limits charge to 80-85% to reduce heat and extend battery longevity.
• [ ] Charge in a cool room — Bedroom at normal room temperature (18-22C) is ideal.
• [ ] Use a charger with minimal LED lighting — Bright status lights can disrupt sleep.
• [ ] Do not charge under pillows — Even if it seems convenient, this is not safe.

Regular Maintenance

• [ ] Inspect cables and connectors quarterly — Replace anything with fraying or damage.
• [ ] Clean charging surfaces — Dust and debris accumulate and reduce charging efficiency. Wipe with a dry cloth periodically.
• [ ] Monitor for new sounds — Crackling or popping from a previously silent charger can indicate failing components.
• [ ] Check charger temperature — Your charger should be warm, not hot. Consistently hot chargers should be replaced.

Battery Health

• [ ] Enable battery protection / adaptive charging — All major phone manufacturers offer this in Settings > Battery.
• [ ] Charge in the 20-80% range when possible — Full cycles from 0-100% daily wear the battery faster than partial cycles.
• [ ] Avoid charging in hot environments — Heat is the primary accelerator of battery capacity loss.
