Safety: Power banks contain lithium-ion cells. Use the cables the manufacturer supplies or recommends, keep the unit away from heat, and follow the manual.
The EcoFlow 25,000mAh 170W Dual 140W Power Bank lists 170W total output with two USB-C ports rated at 140W each and a 33W USB-A port, from a 25,000mAh battery. It also has a TFT display and a stated TSA carry-on standard.
This review is based on the manufacturer listing and specifications. It suits people who want two high-power USB-C ports in one bank. See more options in our Laptop Power Banks category.
Our Verdict
The strongest point of the EcoFlow 25,000mAh 170W Dual 140W Power Bank is the pair of 140W USB-C ports, which lets two high-draw devices connect without one being limited to a lower tier. The 170W total is shared, so both ports cannot run at 140W at the same time.
The trade-off is that the listing does not name a warranty length or the cable in the box. It suits someone who charges a large laptop and another demanding device together; a single-laptop user may not need the second port.

Capacity and Output

The listing describes 140W Power Delivery two-way charging, which also lets the bank recharge quickly from a high-wattage charger.
Charging and Setup
For 140W output you need a cable rated for it, and the listing does not say which cable ships in the box. Check the product page before relying on the bank for a large laptop.
The TFT display shows real-time battery level, power status and charging details, which helps you see how power is shared.
Build, Size and Portability
The listed dimensions are 6.18 x 2.12 x 1.92 inches and the weight is 20 ounces. That is a typical size for this capacity.
EcoFlow states that it meets TSA carry-on standards. Airlines set limits by watt-hour rating, so confirm the figure printed on the unit and your airline policy.
Features and Compatibility
An advanced battery management system provides protection against overcharging, overheating and short circuits, as the manufacturer describes it.
The listing describes charging a laptop, phone and tablet at the same time. It does not list specific laptop models, so compare your charger rating with the port figure.
