Anker Prime 26K vs UGREEN Nexode 25K

The two highest-scoring travel power banks in the catalog, separated by one hundredth of a point. A head-to-head on rated energy, output, recharge input, weight, and what the observed prices can and cannot tell you.

The short answer

Do you actually need 300 watts?

The Anker moves power more than twice as fast in both directions, 300W out against 145W and 250W in against 65W, and carries 99.75Wh against 90Wh. The UGREEN is 87 g lighter, carries more rated energy per kilogram, and costs a fraction as much at the prices observed. The scores are 8.84 and 8.85, which is a tie: this is a choice about whether you need the charging speed, not about which is better.

Decision matrix

Charging speed against everything else.

Standouts are calculated from the products you are viewing. Ties, missing values, and prices in different currencies receive no winner. More capacity or output is a specification advantage, not a promise that a product is better for everyone.

Written analysis

Anker Prime 26K vs UGREEN Nexode 25K

Mouaad Sekkouri, Founder and researcher

The widest gap

300 watts out and 250 watts in, against 145 and 65.

The Anker publishes more than twice the total output and nearly four times the recharge input. Output matters if you are charging a laptop and a phone and a camera at once rather than one device at a time. Input matters more often than people expect: it is how quickly the pack itself refills from a wall socket during a short hotel stop, and a 65W input on a 90Wh pack is a long wait. Both publish the same 140W from a single USB-C port, so for charging one laptop they are equivalent.

The other direction

The UGREEN carries more energy per kilogram and costs far less.

At 90Wh and 513 g the UGREEN works out at roughly 175 Wh per kilogram, against about 166 for the Anker at 99.75Wh and 600 g. That is a derived figure from two published ones, and it is shown in the matrix with the arithmetic visible rather than stored as a specification. The 87 g difference is carried on every leg whether the pack is used or not.

Which one is for you

  1. 01

    Choose the Anker if you charge several things at once

    300W total output and 250W recharge input are the two figures nothing else in this catalog matches.

  2. 02

    Choose the UGREEN if you are carrying it, not racing it

    Lighter, denser in watt-hours per kilogram, and far cheaper at the prices observed.

  3. 03

    Check the Anker against the limit

    99.75Wh clears the common 100Wh threshold by a quarter of a watt-hour. It is under the limit, and it is the smallest margin here.

  4. 04

    Ignore the score difference

    One hundredth of a point is arithmetic, not a recommendation. Neither has been load-tested by Travistello.

What this cannot tell you

Every figure here is a manufacturer specification.

Sustained output under heat, how much of the rated energy actually reaches a device, and how either pack behaves after two years of travel are exactly what a specification sheet cannot establish. Nothing on this page has been measured by Travistello, and the score model says so in its own methodology rather than in the small print.
