Anker Prime A1339 9,600mAh 65W Power Bank: features, specs and who it suits

The Anker Prime A1339 is a small power bank with 9,600mAh of capacity and up to 65W of output. Its main trick is a built-in AC plug, so the same unit works as a wall charger at a socket and as a battery pack on the move. This page explains what the numbers mean and who a pocket-sized, high-output power bank is for.

What 65W output means

Watts measure how quickly power flows. A phone usually charges at well under 30W, while many ultrabooks and tablets can use 45W to 65W. Anker says the A1339 delivers up to 65W, and it lists PD 3.0 (USB Power Delivery) and PPS (Programmable Power Supply) support. These are standard fast-charging protocols that let a charger and device agree on voltage and current.

The listing adds an important detail. The full 65W is available only when a single port is in use. With several ports in use, the USB-C1 port provides up to 45W and USB-C2 up to 20W. Output also depends on the connected device.

A wall charger and a power bank in one

The built-in AC plug folds out so you can plug the unit straight into a socket. Anker says it also serves as a wall charger and comes with a charging cable. It can charge a device from the wall while it refills its own battery, though how the unit shares power between the two depends on its design, so check the manual. Anker lists 30W fast recharging for the unit itself.

Capacity in context

Capacity in milliampere-hours (mAh) is quoted at the cell voltage, so real energy delivered to a device is lower after conversion losses. At 9,600mAh the A1339 is a compact size, enough for a phone charge or two or a partial laptop top-up, rather than a full day of laptop work. Anker lists a weight of 10.76 oz and dimensions of about 4.5 x 1.7 x 1.7 inches, so it fits in a pocket or bag.

The smart display

A 1.3-inch smart LCD shows battery level and real-time power output, according to Anker. Seeing live wattage is useful for checking that a laptop is charging at the speed you expect.

What's in the box

Anker lists the power bank, a 3.3 ft (1 m) braided USB-C to USB-C cable rated at 100W, a travel pouch, a welcome guide and a 24-month warranty.

Who it suits

It suits commuters and travellers who want one small device that charges a phone, tablet or USB-C laptop and also works as a plug-in charger in a hotel room or office. It is less suited to people who want maximum capacity.

What to check before you buy

• Your device's needs: look at the charger wattage printed on your laptop or phone. If it needs more than 65W, charging may be slow.
• Multiple devices: remember the 45W and 20W split when two ports are in use.
• Plug type: check that the built-in plug fits the sockets where you will use it.
• Travel rules: airlines set limits on power bank capacity and carry-on handling, so check your carrier's current rules.
• Cable: confirm your devices use USB-C.
