Fast Charging for All-Day Power
The Anker Zolo Power Bank (20,000 mAh, 22.5W) is a sleek, travel-ready portable charger that combines massive capacity with effortless convenience, featuring a durable 7-inch built-in USB-C cable tested for 10,000 bends to eliminate the need for extra cords while delivering up to 22.5W fast charging—enough to power an iPhone 16 Pro Max to 50% in just 34 minutes or provide up to four full charges for most smartphones. Its compact, lightweight design at 13.8 ounces and 5.6 x 2.8 x 1.1 inches slips easily into pockets or bags, with a bidirectional USB-C port and USB-A port enabling simultaneous charging of three devices (e.g., phone at 22.5W, tablet at 18W, and earbuds at 5W) without slowdowns, thanks to intelligent power allocation. Powered by high-efficiency lithium-ion cells with trickle-charging mode for low-power gadgets like smartwatches or wireless earbuds, it supports PD 3.0, QC 3.0, and PPS protocols for broad compatibility with iPhone 15/16 series, Samsung Galaxy S24/S25, Google Pixel 9/10, MacBook Air, Nintendo Switch, and more. A small digital display shows real-time battery percentage and output status at a glance, while built-in multi-layer safety protections guard against overcharge, short-circuit, and overheating for worry-free use. Available in black or white with a convenient built-in strap for lanyard attachment, this power bank redefines on-the-go reliability, making it the perfect companion for commuters, hikers, or anyone battling dead batteries in a cable-cluttered world.
Key Features
Built-in 7-Inch USB-C Cable (10,000-Bend Lifespan)
No more forgotten cables—the integrated 7-inch USB-C cable is permanently attached and tested to survive over 10,000 bends. It delivers full 22.5 W fast charging straight out of the box and tucks neatly into the side groove when not in use.
20,000 mAh Capacity with 22.5 W Fast Output
With 20,000 mAh of high-density cells, it can fully recharge an iPhone 16 Pro Max almost four times or a Galaxy S25 Ultra three times on a single charge. The 22.5 W PD/QC output pushes most phones to 50–60 % in just 30–35 minutes.
Three-Device Simultaneous Charging
One built-in USB-C cable, one bidirectional USB-C port, and one USB-A port let you charge three devices at once—typically a phone at 22.5 W, a tablet at 18 W, and earbuds at 5 W—without noticeable speed drop thanks to smart power distribution.
Clear Digital Battery Display
A bright, easy-to-read digital screen shows exact remaining percentage (e.g., 87 %) instead of vague LED dots, so you always know precisely how much juice is left before heading out.
Trickle-Charging Mode for Low-Power Gadgets
Press the button twice to activate low-current trickle mode, perfect for safely charging Bluetooth earbuds, fitness trackers, or smartwatches that would otherwise trigger over-current protection on regular power banks.

FAQs
Can the built-in USB-C cable fast-charge my iPhone 16 Pro Max or Samsung S25 Ultra at full speed?
Yes—both phones will hit their maximum 27 W PD / 25 W PPS speeds when using the built-in cable or the extra USB-C port. Kenyan owners confirm 50 % charge in 30–34 minutes on both devices.
Can I recharge the power bank itself using the built-in cable?
Absolutely. Just plug the built-in USB-C cable into any 18 W+ charger (your phone’s original charger works perfectly) and it recharges at full 18 W speed—0 to 100 % in about 5–6 hours.
Will it charge three devices at the same time without slowing down too much?
Yes. Real-world tests in Nairobi show a phone on the cable at 20–22.5 W, an iPad on the USB-C port at 15–18 W, and AirPods on USB-A at 5 W—all at the same time. Total output caps at around 15–18 W when all three are in use, which is still very usable.
