UGREEN launches 25W MagSafe battery pack with liquid cooling for iPhone

UGREEN rolled out a new 25‑watt MagSafe battery pack for iPhone on Tuesday, adding a liquid‑cooling system to its 10,000‑mAh power bank. The device, marketed as a Qi2.2‑compatible charger, plugs into the iPhone’s magnetic ring and promises up to 25 watts of power while keeping its temperature low enough to avoid the throttling that can slow charging. It is the company’s first portable charger to use a built‑in cooling fluid, and it will be sold worldwide through UGREEN’s website and major retailers.

The launch comes as iPhone users increasingly rely on fast wireless charging but complain about heat buildup that can shorten battery life. Apple’s own MagSafe accessories deliver up to 15 watts, and third‑party makers have pushed the limit to 30 watts, often at the cost of higher temperatures. Industry analysts say that managing heat is the next hurdle for wireless power, especially as phones grow larger and power‑hungry. UGREEN’s move follows a trend of adding active cooling to laptops and high‑end smartphones, but it is the first time a portable charger has used a sealed liquid loop to dissipate heat on the go.

The battery pack holds 10,000 mAh, enough for a full charge of most iPhone models and a partial charge of an iPad. Its liquid‑cooling chamber contains a non‑conductive fluid that circulates when the charger detects a temperature rise above 35 °C, moving heat away from the coil and the phone. In early tests, the pack stayed below 38 °C even when delivering a constant 25‑watt charge for 30 minutes, a noticeable drop from the 45 °C seen in similar chargers without cooling. UGREEN lists the price at $79.99, positioning it between budget chargers and premium offerings from Apple and Belkin. Reviewers have praised the cooler feel but note the added weight of the cooling module, which makes the pack about 250 grams heavier than comparable models.

UGREEN says the battery will ship in the United States and Europe next week, with additional colors planned for later in the year. If the cooling system proves reliable, it could set a new standard for wireless power accessories and push other manufacturers to adopt similar technology. Consumers who need fast, safe charging on the move may find the added expense worthwhile, while the industry watches to see whether liquid cooling becomes a staple rather than a novelty.
