Anker clears China for 20,000mAh 55W Zolo power bank

Anker has moved closer to launching a new Anker Zolo power bank with built-in cables after securing mandatory 3C certification in China. The device packs 20,000mAh of capacity, delivers up to 55W of output, and is expected to comply with the new GB 47372-2026 safety standard.

According to ChargerLAB, the certification documents point specifically to the Anker Zolo model with integrated cables. The filing lists an energy capacity of 74Wh, which corresponds to roughly 20,000mAh. It is also the first next-generation Anker device to complete China’s required certification process under the updated safety rules.

The listed specs include:

• 74Wh energy capacity, or about 20,000mAh
• Two built-in USB-C cables
• One USB-C port and one USB-A port
• Up to 55W output from the USB-C port and built-in cables
• Up to 45W input for recharging the battery itself
• Up to 33W from the USB-A port
• 55W maximum total combined output

This setup targets a familiar sweet spot. 20,000mAh remains one of the most popular sizes for travel and light laptop use, while built-in cables remove the need to carry an extra cord. Anker is far from alone here: Baseus, Ugreen, Xiaomi, and several smaller brands already sell 20,000mAh batteries with fast charging and multiple ports.

The new GB 47372-2026 standard matters for both manufacturers and buyers. After a series of tighter rules, certification has become a more significant gatekeeper for products trying to reach store shelves in China. For Anker, passing 3C early gives it more room before launch and a clearer path into one of the world’s biggest portable power markets.
