## Description

If you need portable power for a phone or tablet while away from an outlet, the AsperX AX369 combines a 20,000mAh battery with a built-in USB-C cable. Its display shows the remaining charge, so you can check power at a glance. Need to charge more than one device? The three-port setup gives you USB-C and USB-A options for everyday carry and travel.

## Tips for day-to-day use
Keep the integrated 1.05 ft braided USB-C cable ready for quick top-ups without carrying a separate cable for a USB-C device. For other devices, use the USB-C or USB-A port with a compatible cable. When charging several devices at once, the combined output is limited to 15W, for a faster single-device charge, use one port at a time.

The digital display makes it easier to judge when the power bank needs recharging than a simple set of indicator lights. To recharge the power bank at its 45W input rate, use an adapter rated at 45W or higher. The manufacturer estimates a recharge time of 4–5 hours with that input, the actual time depends on the adapter used.

## What you’ll notice day to day
The built-in cable helps keep a bag or desk setup tidy, while the display provides a clear readout of remaining power. A 45W USB-C output supports fast charging for compatible devices, and the USB-A port adds another connection option. The listed compatibility includes iPhone, iPad, Samsung Galaxy, Google Pixel, earbuds, and other USB-charging devices.

For smaller devices such as earbuds, watches, or mini fans, Small Power Mode is designed for low-draw charging. Activate it with a long press of the power button, the display changes to indicate the mode. This gives the charger a practical role beyond phones and tablets, whether you’re packing for a trip or keeping everyday accessories powered.

Compared with a power bank that relies on separate cables, the integrated USB-C lead offers a more ready-to-use setup. The additional ports are useful when you carry devices with different charging connections, while the screen helps you keep track of the pack’s charge level.

## Before you decide
Can it charge multiple devices at the same time? Yes. It has three charging connections, and the combined output when using multiple ports is limited to 15W.

How do you charge the power bank itself? Connect it through the USB-C input. For 45W input, use an adapter rated at 45W or higher, the stated recharge estimate is 4–5 hours with that input.

Can it charge small accessories? Small Power Mode is intended for low-draw devices such as earbuds, watches, and mini fans. Use the power button to activate or exit the mode.

## Is it worth it?
The AsperX AX369 is well suited to people who want a high-capacity charger with its USB-C cable built in, a readable charge display, and several charging connections. It’s a practical fit for travel, commutes, and days when phones, tablets, or smaller USB accessories need portable power.
