Belkin has launched a new 45W GaN wall charger in China, and the main draw is a built-in USB-C cable that pulls out when you need it and disappears when you don’t. The Belkin 45W Retractable GaN Wall Charger, model WCH023, is priced at 199 yuan ($28) and is already on sale through JD.com.
This compact charger is designed for travel and everyday carry. It has foldable prongs, weighs 145 grams, and measures 65 x 52 x 38 mm. The retractable cable stretches to 0.8 meters, and Belkin says the reel mechanism is rated for 20,000 cycles while the cable can handle 5,000 bends and a 10 kg load.
45W output and dual-device charging
The charger can deliver up to 45W to a single device, whether you use the attached cable or the front USB-C port. Plug in two devices and the power is split to 25W and 20W. It supports USB PD 3.1 and PPS, so it is aimed at mainstream phones and small gadgets rather than laptops. Belkin says the 45W output can take an iPhone 17 Pro to 50% in 20 minutes, or a Samsung Galaxy S25 Ultra to 50% in 25 minutes.
GaN efficiency and recycled plastic
Inside, the charger uses gallium nitride components, and Belkin claims 92% power conversion efficiency plus a temperature drop of about 10 degrees Celsius versus older non-GaN chargers. That is the sort of engineering improvement that matters more than marketing copy: less wasted heat usually means a smaller charger that stays cooler for longer.
It also includes active temperature monitoring and protection against overvoltage, overcurrent, and short circuits. The outer shell is made from 90% post-consumer recycled plastic, which is increasingly becoming table stakes for accessory brands that want to look modern without pretending cables are fashion items.
Compact charger competition
Belkin is not alone in chasing the pocketable charging crowd. Anker recently unveiled a 160W smart charger with proprietary fast charging for Huawei and Xiaomi devices, while Baseus showed off a tiny 100W GaN charger with foldable plugs. The difference here is simpler: Belkin is betting that convenience, not raw wattage, is what most buyers actually notice every day.
The open question is whether the retractable cable becomes the feature everyone copies or just another neat idea that disappears into the accessory graveyard. If the price stays aggressive outside China, this one has a decent shot at becoming the charger people recommend after one too many tangled cables.
