Pros and cons

Pros

Three ports provide USB-C and USB-A charging options.
The listing claims 165W total output and support for simultaneous laptop charging through the USB-C ports.
The display is described as showing battery level and input or output wattage.
Listed dimensions are about 6 inches long, with a stated weight of 500 g.

Cons

At 500 g, it is a substantial carry for a 20,000mAh power bank.
The bank's stated maximum recharge rate is 65W, so recharging it can take time and depends on the adapter used.

What to know before buying

USB-C charging works only with devices whose USB-C ports support charging. The manufacturer states that recharge speed depends on the adapter and caps the bank's recharge rate at 65W.
The stated 20,000mAh is battery capacity. The listing separately estimates 12,000–16,000mAh delivered after energy losses, so usable capacity will be lower than the nominal figure.

Listing details to confirm

The 165W total output claim is presented as 100W plus 65W, while the connector listing describes two 100W USB-C ports and one 30W USB-A port. The listing does not clearly explain port-by-port limits or how total output is allocated. It also calls the power source “Corded Electric” for a rechargeable power bank. Confirm the output configuration and intended meaning of that field before buying.

Who is it for?

A good fit for

Laptop users who want a portable backup with two USB-C ports and a separate USB-A port.
Photographers or drone users who need to recharge compatible devices away from an outlet.
Buyers who value a display for checking charge level and power information.

Less suited to

Anyone prioritizing a very light power bank for daily pocket carry.
Buyers who need a confirmed port-by-port simultaneous output configuration or faster-than-65W bank recharging.

Customer feedback highlights perceived charging speed and the ability to charge multiple mobile devices. One customer cited a day of drone and photography work as a useful scenario. That reported use aligns with the listing's three-port setup and stated compatibility, though actual results depend on device requirements and the unclear output allocation. Rating data is generally positive but includes a smaller low-star portion, and it does not establish specific reasons for those ratings.

Customer feedback describes charging speed and overall performance positively.
Customers are reported to appreciate charging multiple mobile devices.

Frequently asked questions

Can the AX328 charge a laptop and another device at the same time?

The listing claims the two USB-C ports can supply 100W and 65W simultaneously. However, its port details and total-output claims are not fully consistent, so confirm the port-by-port limits for your intended setup.

How quickly does the power bank itself recharge?

The manufacturer lists a maximum recharge rate of 65W. Actual speed depends on the charger adapter, and the listing recommends an adapter of at least 20W.

Will it charge any device with a USB-C port?

Not necessarily. The device must support charging through USB-C. Some computer USB-C ports are described as data-only.

What does the display show?

The manufacturer says the color TFT display can show battery percentage, remaining runtime, input and output wattage, and cell health.
