## Description

When you need backup power for more than one device or person, this Miady two-pack offers a charger for each bag, desk, or travel kit. Each slim power bank has a 10,000mAh capacity and built-in Lightning and USB-C cables, so charging a compatible phone does not have to start with finding a separate cable.

The set combines two portable chargers in black and white, with USB-A and USB-C connections for flexible everyday use.

## On-body feel

The slim, pocket-size design is made to travel in a backpack or pocket, keeping a charger close for commutes, day trips, and time away from an outlet. Built-in cables help reduce the number of loose accessories to carry. With two chargers in the set, one can stay in a travel bag while the other is kept handy at home or work.

## Where it shines

Use the built-in Lightning cable for compatible iPhones and the USB-C cable for compatible Android phones and other USB-C devices. The charger also has a USB-A port, giving you another way to connect a device. Its three output options are useful when several personal devices need power in the same place, the product description says it can charge three devices simultaneously. This can be handy while traveling with a phone, tablet, or wireless earbuds.

Recharging the power bank is flexible, too: use its built-in USB-C cable or the USB-C input port with your own charger. That makes it easier to fit recharging into different routines, whether at home, in a car, or while preparing for a trip. The product is listed at 37Wh and described as suitable for air travel, making it a practical backup for travel days as well as daily use.
