Mistakes to Avoid
1. Relying on high-capacity packs for laptop charging without verifying output wattage.
Why it hurts: 22.5W models such as the ZZI or OHOVIV chargers are optimized for phones but lack the speed needed for most modern laptops.
Do instead: Look for 65W or 87W options like the JUOVI or Anker models to sustain power-hungry hardware while traveling.
Jargon Decoder
- mAh (Milliamp Hours)
- A unit measuring the total electrical energy stored in a battery pack.
Why it matters: A higher rating, such as the 60,000mAh reserve in the ZZI, allows for more device recharges during long trips without a wall outlet.
