Power Banks to AVOID

❌ Anything under $15: Fake capacity ratings, poor safety, will die in 6 months.

❌ No-name Amazon brands: Inflated mAh claims. A “50,000mAh” bank for $20 is lying.

❌ Power banks without PD (Power Delivery): Slow charging. Not worth it in 2025.

❌ Bulky “solar” power banks: Solar panels are too small to be useful. Gimmick.

Pro Tips

Charge your power bank overnight: They take 2-4 hours to fully charge.

Use a good cable: Cheap cables limit charging speed. Get a 100W USB-C cable.

Don’t drain to 0%: Lithium batteries last longer if you keep them between 20-80%.

Buy from reputable brands: Anker, UGREEN, Baseus, RAVPower. Skip no-name brands.
