SHENZHEN, CHINA – Shenzhen Charmast Technology Co., Ltd. is thrilled to announce the launch of its new product, the Charmast Portable Charger with Built-in Cables. This innovative device is a game-changer in the portable charging industry, designed to provide a seamless, hassle-free charging experience to users while on the go.

The Charmast Portable Charger is not just any power bank—it’s a 7-in-1 device that features built-in USB C, Micro, and other three cables integrated for all phones. It also houses additional 5V/3A USB C and USB A ports to provide faster charging/recharging speeds. The device’s unique LCD display keeps users informed about the remaining power level visually, taking the guesswork out of charging.

In a significant departure from traditional portable chargers, the Charmast Portable Charger comes with a built-in wall plug. This unique feature enables users to recharge the battery pack by directly plugging it into the wall—eliminating the need for a separate, bulky charger. The built-in cables further add to the convenience, freeing users from the hassle of tangled, messy charging cables. This feature makes the Charmast Portable Charger a perfect travel companion for family, friends, camping, hiking, and traveling.


Despite its robust feature set, the Charmast Portable Charger is remarkably compact. Measuring just 5.95″ x 2.76″ x 0.72″ and weighing just 0.5 lbs—lighter than a cup of water—it’s designed to fit comfortably in the palm of your hand or in your pocket. The USB A or USB C output supports up to 5V-3A fast charging, making this ultra-slim USB C battery bank a must-have accessory.

The Charmast Portable Charger is also a powerhouse when it comes to charging multiple devices. With its up to 5 outputs, it can charge simultaneously (3 cable outputs, USB A output, and an additional USB C output). It can automatically detect and adjust the charging current for the fastest charging, providing a powerful total of 15W to charge four devices at the same time.

With the Charmast 10000mAh Portable Charger, users will also receive a mesh pouch for convenient carrying, a 24-month warranty, and lifetime technical support—offering peace of mind to users about the product’s quality and reliability.

“Charmast is committed to revolutionizing the way people charge their devices. With the introduction of our new Charmast Portable Charger with Built-in Cables, we are taking a significant step in that direction,” said Jason Beck, contact person for Shenzhen Charmast Technology Co., Ltd. “We believe our customers will love the convenience, speed, and portability that our new product offers.”
