Technical comparison
Specification contextSpecification rank #1 among power banks: nameplate capacity 25,000 mAh; maximum output 165 W. Published inputs, not our lab test.
Published comparison inputs
Published features
Why the specification score is 84.4
277.8 mAh and 1.8 published watts per £1 at the checked price.
165 W published maximum; sustained and multi-port limits may differ.
25,000 mAh nameplate capacity; delivered Wh is not measured.
Published features: built-in cable, display. Unverified convenience fields receive neutral half-credit rather than being asserted absent.
Exact manufacturer product page, SKU and GTIN; 1 review pools.
Evidence report
What matters, what we know and what is missing
This is a specification-ranked comparison report, not purchase advice. It uses the category evidence profile below and keeps hands-on findings separate from the published specification score.
Controlled delivered-energy testing with voltage, protocol and termination conditions.
No exact-model hands-on synthesis is published. This report covers sourced comparison inputs, coverage and open gaps; it makes no claim about real-world performance beyond retained sources.
Inside the bounded published category method.
Across 15 factor-removal and weight-change scenarios.
3 blocking gaps remain.

Hands-on state: not collectedTimed recharge using a disclosed charger, cable and input protocol.
Hands-on state: not collectedObserved or measured temperature under sustained charging and discharging.
Hands-on state: not collectedDirect compatibility and power-allocation testing while input and output are active.
Hands-on state: not collectedVerified weight, dimensions, cable design and hands-on carrying context.
Hands-on state: not collectedDirect charging tests with named devices, ports, cables and negotiated protocols.
Hands-on state: not collectedHands-on gate: Resolve the exact SKU and cell configuration. Performance claims require controlled delivered-energy or output measurements; otherwise report nameplate values only.
Nameplate capacity does not establish usable delivered energy at a stated voltage and load.
Peak output does not establish sustained multi-port power, temperature or cycle-life performance.
Normalized decision receipt
9 mapped fields each carry a canonical receipt hash and an origin status. Source access time is kept separate from field observation, so a configured value is not presented as freshly re-extracted.
sha256:415beb8c6685e5879884580ec3ee4d3ecfb7b0380917d4f0c129e15087641f00The score and rank compare retained specification inputs inside this bounded category cohort. They are not a hands-on quality verdict and are not comparable across categories. Open evidence gaps block purchase advice regardless of specification score, rank, offer state or review-synthesis verdict.
Source notes and limitations
Evidence limitations
- Capacity is nameplate mAh, not independently measured delivered energy.
- Maximum output is a published boundary condition; sustained and shared-port output can differ.
- No calibrated discharge, thermal or cycle-life test is claimed by Agent Review Data.
- The manufacturer-direct offer can change after its checked time.
Recommendation caveats
- Ranking compares manufacturer specifications and checked price; it is not a discharge or thermal test.
- The manufacturer-direct offer was in stock when checked.
- Nameplate mAh is not the energy delivered to a device after voltage conversion losses.
- Owner-feedback coverage is too narrow for an internet-wide consensus claim.

Follow the decision back to the source
This pilot preserves real claim IDs and source links for two products. Missing hashes, snapshots and calculations stay explicit rather than being reconstructed from page content.
How the stored score reaches 84.4
Capacity and output per pound
Uses the dated manufacturer-direct price with published capacity and output.
Published maximum output
Scores the published 165 W boundary while retaining its two-device and per-port limitations.
Nameplate capacity
Scores nameplate capacity while exposing the manufacturer FAQ's lower delivered-capacity range.
Convenience features
The stored scoring method credits the built-in cable and display features. Unverified convenience fields receive neutral half-credit.
Identity and evidence
Credits exact identity and one source-specific review pool. It does not treat the owner pool as independent performance.

Important qualifications and shared origins
anker-delivered-capacity → anker-capacityThe manufacturer FAQ explains that delivered device-side capacity is lower than nameplate capacity.
anker-multi-device-output → anker-total-outputThe 165 W maximum applies to two devices; three or four devices have a lower published limit.
anker-single-port-output → anker-total-outputOne USB-C port is limited to a published 100 W maximum.
anker-offer-availability → anker-offer-pricePrice and availability were observed together and are both historical.
What could change the answer
No controlled Wh discharge curve across device voltages and loads is retained.
Published maxima are conditioned by port combination and do not establish sustained output under heat.
No independent thermal trace, protection-trigger test or repeated-cycle capacity record is retained.
Why purchase advice is blocked
No controlled delivered-energy, sustained-output or thermal measurement is retained.
A recorded second-person review of the leading product and close alternatives has not been completed.
Only one manufacturer-direct offer observation is retained.
The pilot retains selected short excerpts and links, but no source hash or archived snapshot.
