## Description

Some cold-weather outings need power for heated gear, others also call for a way to charge a phone or another USB device. The THEKUKU X1 combines 7.4V DC and 5V USB outputs in one 30,000mAh battery pack. Its LED display makes it easier to track remaining charge. It’s designed for compatible heated clothing and seating, with USB power available for everyday devices.

## Key features

The 7.4V DC output is intended for heated apparel and gear, while the 5V USB output supports compatible USB devices. That dual-output setup gives you an alternative to a basic 5V-only power bank when your winter gear needs DC power. The product is also described for use with heated vests, jackets, pants, blankets, sleeping bags, camping chairs, and stadium seats.

A built-in digital display shows the remaining battery percentage from 0 to 100%, so you can check charge status before heading out or during a break. The listed runtime is 4–10 hours across High, Medium, and Low heat settings. The Type-C input is used to recharge the pack. Customers describe it as lasting through extended outings and appreciate its versatility, feedback on its weight is mixed.

## Best use cases

For a game in cold weather, camping, skiing, or another outdoor activity, the X1 can supply power to compatible heated gear while providing a separate 5V USB output for a phone or other device. It can also suit someone who wants one battery pack for different types of heated equipment, rather than a 5V-only pack that does not serve gear requiring 7.4V DC. The right choice depends on the voltage and connector your item uses.

## How to use it

Match the heated item’s power requirements and connector to the battery pack before connecting it. The listed accessories include a USB-to-DC cable and a 4.0mm-to-3.8mm adapter cable for compatible connections. Connect the garment or other heated item to the DC output, then use the 5V USB output for a compatible device. The outputs are described as operating independently, allowing heated gear and a USB device to be powered at the same time. Check the LED display to monitor the remaining charge, and select the heat setting on your gear to suit the outing.

## What to clarify

**Which heated clothing or seats can it power?** It is intended for heated apparel and seating that match its 7.4V DC output and connection. The product information identifies 3.8mm and 4.0mm DC connectors, confirm that your item uses a compatible connection before use.

**Can it power heated gear and charge a phone at once?** Yes. The 7.4V DC and 5V USB outputs are described as independent, so compatible heated gear and a USB device can be connected simultaneously.

**Is the display bright while sleeping?** The display lights briefly when checking status or powering on, rather than staying illuminated throughout the night. This can help avoid a continuously lit screen when using it with a heated sleeping bag.

## Is it worth it?

The THEKUKU X1 is a practical fit for people who need a 7.4V power source for compatible heated gear and want 5V USB output in the same pack. Its 30,000mAh capacity, charge-percentage display, and support for a range of heated apparel and seating make it especially useful for outdoor plans where checking power and managing more than one device matter.
