A power bank is basically a spare battery in your pocket. Our Stockton, CA customers usually ask for one after a dead phone ruins a day, and the right size depends on whether you want something slim or something that lasts. Here’s how to choose.

Power Bank Types

Portable Power Bank

A portable power bank is a general-purpose battery for everyday carrying. Check the ports and output.

10000 mAh Power Bank

A 10000 mah power bank is the most popular size, giving about two charges for many phones. Real results are a bit lower because of conversion losses.

Portable 10000mAh Power Bank

A portable 10000mAh power bank balances size and capacity, small enough for a bag and big enough for a day out.

Fast Charging Power Bank

A fast charging power bank supports Power Delivery, so check the wattage if you want quick top-ups.

Best Portable Charger for iPhone

The best portable charger for iPhone has a USB-C PD port. Magnetic ones snap on and charge wirelessly, with slower speed.

Slim Power Bank and 5000mAh Slim Power Bank

A slim power bank fits in a back pocket. A 5000mAh slim power bank gives roughly one full charge, which is fine for emergencies.

Pair It With the Right Cable

A good charging cable matters. See also wall chargers for recharging the bank, and all phone accessories.
