Specifications

Official Anker support specifies a 20,000mAh capacity, USB-C input/output up to 65W, USB-A output up to 22.5W, 87W maximum total output, dimensions of approximately 15.75 × 7.35 × 2.6cm, and a weight of 430.91g.

Powerful 20,000mAh Capacity

The Anker A1383H11 features a large 20,000mAh battery, providing substantial portable power for users who need to keep multiple devices running throughout the day.

The increased capacity makes it especially useful for long working days, commuting, business trips, vacations, gaming sessions, and situations where access to a wall outlet may be limited.

Actual usable capacity and the number of device charges will vary depending on the connected device, charging conditions, power conversion losses, and battery efficiency.

Up to 87W Total Charging Power

The Anker power bank can provide up to 87W of total output when charging compatible devices.

When charging a single device through the built-in USB-C cable or USB-C port, maximum output is 65W. The USB-A connection supports up to 22.5W, with Anker specifying a maximum combined output of 87W (65W + 22W).

This makes it capable of charging more demanding USB-C devices, including many compatible laptops and handheld gaming systems, rather than being limited to smartphones.

Built-In USB-C Charging Cable

A major advantage of the Anker A1383H11 is its integrated USB-C cable.

Instead of having to carry a separate cable every time you leave home, the built-in cable is ready for compatible USB-C smartphones, tablets, laptops, power banks, and gaming devices.

Anker states that the integrated cable is designed to withstand more than 10,000 bends, helping make it suitable for frequent everyday and travel use.

Charge Up to 3 Devices

The Anker A1383 offers three charging connections:

• Built-In USB-C Cable
• USB-C Port
• USB-A Port

This allows you to connect up to three compatible devices at the same time, making the power bank particularly useful when carrying a phone, tablet, laptop, gaming handheld, earbuds, or other accessories.

Available charging power is distributed between connected devices, so maximum charging speeds depend on the number and type of devices connected.

Up to 65W Fast USB-C Charging

With maximum single-device USB-C output of 65W, the Anker A1383 can provide considerably more power than a standard phone-focused power bank.

Compatible device categories include:

• USB-C Smartphones
• iPhone Models with USB-C
• Samsung Galaxy Devices
• Google Pixel Devices
• iPad & USB-C Tablets
• MacBook Air
• Compatible MacBook Pro Models
• USB-C Windows Laptops
• Steam Deck & Compatible Gaming Handhelds
• USB-C Power Banks
• Wireless Accessories

Maximum charging speed depends on the connected device and its supported charging protocol. Anker specifically markets the A1383 for phones and laptops, including MacBook charging.

Fast 65W Power Bank Recharging

High charging performance also applies when replenishing the power bank itself.

The USB-C input supports up to 65W, allowing significantly faster recharging when paired with a sufficiently powerful compatible USB-C charger.

Anker states that with a 65W charger, the power bank can be fully recharged in approximately 1.5 hours under its specified test conditions. Actual recharge time can vary depending on charger output, temperature, and operating conditions.

Ideal for Laptops, Phones & Gaming Devices

Thanks to its combination of capacity and output power, the Anker A1383H11 can serve as one portable charging solution for a wide range of electronics.

It is particularly useful for:

• Smartphones
• Tablets & iPads
• USB-C Laptops
• MacBooks
• iPhone USB-C Models
• Samsung Galaxy Devices
• Google Pixel Devices
• Steam Deck
• Compatible Gaming Handhelds
• USB-C Power Banks
