Buyer's Guide

What to Consider When Shopping for the Best Portable Phone Chargers

Before choosing your new portable phone charger, here are a few things you should consider.

Charge capacity: Do you need a portable phone charger to fully recharge your phone every time you use it? You’ll need a charger that can handle multiple charges.

Charge speed: How fast do you need your phone charged? Most top-rated portable phone chargers can charge your phone 50-80% in about 30 minutes.

Device usage: Will you need to use your phone while it charges? Make sure your portable charger can accommodate that.

Travel restrictions: Not all phone chargers are created equal. So if you need yours for air travel, ensure it is safe, approved, and not restricted.

Tips for Shopping for Lithium-Ion Batteries

In addition to the considerations above, here are a few helpful tips for shopping for lithium-ion portable phone battery chargers.

Avoid cheap stuff: While there are cost-effective portable phone charger options, don’t automatically choose the cheapest one. Cheaper batteries may be poorly made and could cause safety concerns, so take time to read reviews carefully before buying.

Battery safety: The portable phone charger battery should be UL- or CE-certified with protection circuits that prevent overcharging, overheating, and short-circuiting.
