A laptop power bank keeps your phone, tablet, and laptop alive through long flights and layovers, but capacity and output vary a lot. This comparison puts one 25,000mAh laptop power bank each from Anker, EcoFlow, and Ugreen side by side on price, total output, weight, cables, and warranty, so you can compare matched capacity models.
How We Chose
We picked three well known charging brands that each sell a 25,000mAh power bank with 100W class USB-C output on Amazon, so the capacity is matched. The total output, ports, and built-in cables differ, and we show them as listed. The Anker, Ugreen and EcoFlow power banks are all available on Amazon. We left out the Belkin 25K because Belkin’s US product page does not show its output or weight and we could not match it to a Belkin specification page for the model sold on Amazon. The Anker listing shows two different weights (10.6 ounces and 21 ounces), so we use the 21.0 ounces on Anker’s own page. Output, weight, and warranty figures come from each manufacturer’s own pages where we could read them, and each table cell names its source. Where a manufacturer page names the exact model, we use its figure instead of the Amazon listing, and we say so where the manufacturer gave none. This is a researched comparison, not a hands-on test of these power banks, so we make no claims about real world charging speed or capacity. Prices are Amazon prices checked in September 2026 and can change.

Frequently Asked Questions
Can I bring a power bank on a plane?
Airlines generally require lithium power banks to be in your carry-on bag and not in checked luggage, and they limit capacity. Check your airline’s rules before you fly, especially for 25,000mAh models.
What does mAh mean on a power bank?
mAh is milliamp hours, a measure of battery capacity. A bigger number stores more energy, but real usable capacity is lower because of conversion losses. Compare watt output for laptop charging.
Will a power bank charge my laptop?
Only if it supports enough USB-C Power Delivery wattage for your laptop. These three list 145W to 170W total output, but check your laptop’s charger rating and the single port output.
Are built-in cables better than separate cables?
Built-in cables mean fewer things to pack, but a damaged cable is harder to replace. Some models here also have USB-C ports so you can use your own cable.
