The Anker 335 PowerCore is a 20,000mAh portable battery with one USB-C port and two USB-A ports, delivering up to 20W over USB-C. That capacity is enough to refill most phones three to four times, and the three outputs let you charge a phone, earbuds and a tablet at once. It sits in the middle of Anker's lineup: bigger and heavier than pocket 10,000mAh packs, but without the built-in cables or higher wattage of Anker's premium models. It suits travelers and commuters who want a dependable multi-device backup without paying for fast-charging extras.

Owners of Anker's 20,000mAh packs generally rate them highly for reliability and capacity, and the 335 follows that pattern. Complaints center on weight and the modest 20W ceiling rather than on failures.
