AI Verdict
This 26,250mAh power bank delivers 300W max output across three ports and recharges at 250W, ideal for users needing to rapidly charge multiple high-power devices like laptops and phones.
This power bank is a strong contender for users who absolutely need 300W total output and 140W single-port charging for demanding devices like MacBook Pros, especially given its 26,250mAh TSA-approved capacity. However, the reported throttling after 60% capacity and potential issues with the included cable mean it's not a perfect fit for everyone expecting sustained peak performance without additional purchases.
If sustained high-wattage output is critical, look for power banks with verified consistent output curves beyond 60% capacity, or consider models with higher individual port ratings that don't share power.

What Buyers Say
The Anker Prime Power Bank is a powerhouse on paper, boasting 300W total output and 140W single-port charging, but user experiences reveal some significant caveats. Many buyers are frustrated by the power bank's tendency to throttle charging speeds dramatically once it drops below 60% capacity, often falling from 250W to 75W. There are also recurring complaints about the included USB-C cable potentially limiting output to 60W, forcing users to buy a separate, higher-wattage cable to unlock the full advertised speeds. Firmware instability and issues with Bluetooth draining the battery are also common themes, alongside reports of overheating and even receiving faulty units upon delivery.
“Man, this thing is fast when it works, but why does it slow down so much after 60%? And I had to buy a new cable just to get the full speed, what a rip-off.”
Common Praise
- Provides 300W total output across its three ports, allowing simultaneous charging of multiple devices.
- Achieves 140W fast charging for laptops, powering a MacBook Pro (M4 Pro) to 50% in 27 minutes.
- Recharges itself to 50% in 13 minutes and fully in 60 minutes with 250W input.
- The 26,250mAh capacity is sufficient for multiple device charges and is TSA-approved for air travel.
- The smart display and app control offer detailed real-time charging information and output adjustments.
- The power bank is built sturdy and durable, with effective thermal management.
Common Complaints
- Charging speed drops significantly after the power bank's capacity falls below 60%, with output reducing from 250W to 75W.
- The included USB-C cable may only support 60W, requiring an additional purchase for full 140W charging.
- Bluetooth connectivity can drain the battery if left on, and it may automatically re-enable itself.
- Users report firmware instability, charging bugs, and difficulty charging devices below 5%.
- Overheating during charging and reports of Dead On Arrival (DOA) units are present.
- The price is considered high, especially given the reported performance inconsistencies.
Ownership Tips
- You'll likely need to invest in a separate, higher-wattage USB-C cable to consistently achieve the advertised 140W output.
- Keep an eye on the power bank's charge level; expect a noticeable drop in charging speed once it dips below 60%.
- Be mindful of the Bluetooth setting; it can drain the battery if not manually turned off, and it sometimes reactivates on its own.
- Monitor for overheating during intensive charging sessions, especially with multiple devices.
- The app provides useful data, but be prepared for potential firmware quirks or occasional charging inconsistencies.
Frequently Asked Questions
Is this power bank approved for air travel?
Yes, its 26,250mAh (99.75Wh) capacity is within the TSA limits for carry-on luggage.
Can it charge multiple laptops at full speed?
It offers 300W total output across two USB-C and one USB-A port, capable of keeping two MacBook Pros running. However, sustained 140W output on both USB-C ports simultaneously might be affected by throttling after 60% capacity.
How fast does the power bank itself recharge?
It can recharge to 50% in 13 minutes and fully in 60 minutes when using both USB-C ports with a 250W max input.
Does it come with a cable that supports its maximum output?
It includes a 3.3 ft USB-C to USB-C charging cable rated for 240W. However, some users report the included cable might cap output at 60W, potentially requiring a separate purchase for full 140W charging.
What kind of information does the smart display show?
The smart display provides detailed charging information, including the power bank's charge level, the speed at which each port is charging, and temperature information.
Buying Guide
When you're looking at a power bank like this, don't just focus on the 'max output' number. That 300W is a total across all ports, and the real-world sustained output for a single device, especially a laptop, is what matters most. Pay attention to the capacity (26,250mAh here) to understand how many full charges you'll get for your devices, and check the input wattage if you hate waiting for the power bank itself to recharge. Also, always verify if the included cables actually support the advertised speeds.
300W Max Output
This is the total power the power bank can deliver across all its ports combined. Think of it like the total horsepower of a car; it tells you the maximum potential, but not necessarily how fast it goes in every situation or how many devices it can push at their individual max speeds simultaneously.
26,250mAh (99.75Wh) Battery Capacity
This number indicates how much energy the power bank stores. A higher mAh means more charges for your phone or laptop. The 99.75Wh is important because it's just under the 100Wh limit for TSA approval, meaning you can take it on a plane.
250W Max Input
This tells you how quickly the power bank itself can be recharged. A high input wattage means you can fill it up much faster, like filling a car's gas tank with a high-flow pump, which is crucial if you need to top it off quickly between uses.
Alternatives
If this power bank doesn't quite fit, look for models with a lower total wattage if you only charge phones, or higher sustained single-port output if you need consistent maximum power for one laptop without throttling. Consider power banks with different port configurations if you don't need a USB-A port, or if you require specific fast-charging protocols like SuperVOOC.
