The Anker Prime 20000mAh Power Bank (A1336) promises a lot: 200W of power, rapid charging, and a compact design. But does it deliver on its lofty claims? After extensive testing, charging various devices from laptops to smartphones, I’m ready to share my thoughts.

The A1336 boasts an impressive array of features. The 200W output, split across two USB-C ports and one USB-A port, is its standout feature. This allows for simultaneous fast charging of multiple devices, a major advantage for those on the go. The inclusion of a smart digital display provides real-time feedback on charging levels and power output, adding to the convenience. Its compact size is another plus, easily fitting into a bag or backpack.

Charging performance was, for the most part, exceptional. I successfully charged two laptops simultaneously, each receiving close to the advertised 100W. The 100W fast charging for the power bank itself also lived up to its billing, consistently taking around 1 hour and 15 minutes for a full recharge. Charging phones and tablets was equally quick and efficient. However, I did notice slightly slower charging speeds with older devices, suggesting the power bank may be less adept at optimizing charging for devices with less advanced charging circuitry.

The digital display was helpful in keeping track of power levels, but the brightness could be slightly improved for better visibility in direct sunlight. The included USB-C to USB-C cable is adequately long for most uses.

Pros:

• 200W total output for simultaneous fast charging of multiple devices.
• Fast 100W recharge time.
• Compact and portable design.
• Informative digital display.

Cons:

• Slightly slower charging speeds with older devices.
• Digital display could be brighter.

The Anker Prime 20000mAh Power Bank (A1336) is a compelling option for those needing high-powered, simultaneous charging. Its ability to quickly charge multiple devices, including laptops, is a major benefit. While some minor drawbacks exist (slower charging with older devices, display brightness), the overall performance is excellent. I highly recommend this power bank for travelers and anyone who needs a reliable and powerful charging solution.
