  • Our take on the Anker Zolo 20000mAh Power Bank

    The Anker Zolo is a 20,000mAh power bank with a built-in 7-inch USB-C cable, one extra USB-C port and one USB-A port. It tops out at 22.5W, enough to take an iPhone to about 50% in half an hour. The built-in cable means one less thing to pack, and Anker rates it for over 10,000 bends. It suits travelers and commuters who want several phone charges without carrying a cable, but it is a large, fairly heavy brick and slower than 30W+ rivals.

    What reviewers say

    Owners like the built-in cable and the charge count, calling it a reliable travel bank. The main complaints are its size and weight and the modest 22.5W speed.

    • CapacityPraisedReviewers report about three to four full phone charges per top-up.
    • Charging speedMixed22.5W is fine for phones but slower than 30W+ banks, so some call it dated.

    About the Anker Zolo 20000mAh Power Bank

    The Anker Zolo is a 20,000mAh power bank with a built-in 7-inch USB-C cable. The cable is tested to withstand over 10,000 bends. The power bank also has an extra USB-C port and a USB-A port, so it can charge more than one device.

    Maximum output is 22.5W fast charging, which charges an iPhone to 50% in roughly 30 to 35 minutes. The capacity provides around 3 to 4 full charges for a typical flagship phone. Pass-through charging lets you recharge the power bank while it charges connected devices.

    ActiveShield technology checks temperature continuously to help prevent overheating.

    Questions and answers

    How many times can it charge a phone?
    About three to four full charges for a typical flagship phone, less for large tablets or if you charge two devices at once.
    Does it charge a laptop?
    Only slowly. At 22.5W it can trickle-charge a USB-C laptop but will not keep up with one in use.
    Can I charge it and a phone at the same time?
    Yes. Pass-through charging lets you top up the bank while it charges a connected device.
    Is the built-in cable replaceable?
    No. The 7-inch USB-C cable is fixed, though Anker rates it for over 10,000 bends.
    Does it come with a wall charger?
    No. You supply your own USB-C charger and, for iPhones, a USB-C-to-Lightning cable.
    Is it allowed on a plane?
    Yes. At 20,000mAh it is under the common 100Wh carry-on limit, but check your airline's rules.

    At Anker US, for $29.99, as of our latest check.
