Summary
A 20,000mAh power bank with a built-in USB-C cable that puts out up to 65W to one device and 87W across three ports. Check the model marking before you buy: the reference version is A1383, and it cannot charge itself and another device at the same time.
Strengths
- 65W over the built-in cable or the USB-C port charges laptops, not just phones.
- The integrated cable folds flush into the body and is rated for 10,000+ bends.
- Three ports (2 USB-C + 1 USB-A) charge three devices at once for 87W total.
- Recharge is fast: about 1.5 hours on a 65W charger, 1h38m measured in testing.
- Measured output was 16,636–17,834mAh usable, 83–89% of rated capacity.
Weaknesses
- No pass-through charging: it cannot power a device while it recharges itself.
- Dual USB-C output throttles one port when both are used together.
- PPS is capped at 4A, so full 45W Samsung charging is not supported.
- The built-in cable is short and flat, and is not user-replaceable.
- The display shows only battery percentage, not wattage.
- 87W is more output than many users need.

Full research notes and sources
Ports and output
The 87W total is shared, not delivered to one device: the built-in cable or the USB-C port carries up to 65W to a single device, and the USB-A port adds 22.5W. Using both USB-C outputs at once throttles one to 5V/3A or 9V/3A, and the official manual lists splits such as 45W + 42W. PPS is limited to 3.3–11V at up to 4A, so a Samsung Galaxy Ultra tops out around 38W instead of the full 45W mode.
Capacity and charging
Anker rates the cell at 20,000mAh and about 72Wh, and estimates 30–45% is lost to the cells and conversion, leaving an estimated 11,000–14,000mAh for devices. Charge-Test measured 16,636–17,834mAh usable, 83–89% of rated. A full recharge takes about 1.5 hours on a 65W charger; the tested unit took 1h38m. There is no pass-through charging, so you cannot charge the bank and a device at the same time.
Repairs and support
The built-in cable is a single point of failure; NotebookCheck notes it would not be replaceable if it broke, and no repairability or parts information for this model was found. Anker’s UAE store and SmartGadgetKit list an 18-month warranty, while the US page states a hassle-free warranty without a stated duration in the content read; treat the US term as 18 months.
Anker’s US store lists the bank at $69.99 (2026), and Newegg’s Anker store showed the same figure. Charge-Test listed it around €50 in Germany. In the $61–75 band it is good value for laptop-class output and the built-in cable; buyers who only charge phones can spend less on a smaller 22.5–30W bank.
