Review verdict#3

Two controlled test groups support solid delivered energy, high USB-C output and fast recharge. It remains a capable mature option, but newer models improve either peak performance or cable convenience.

About this result
Secondary specification scopeEligible for specification comparison
Purchase adviceNot currently supported

Secondary specification rank #5 compares published inputs inside the tracked category cohort. It is not the review-led quality result or a reviewed instruction to buy this product.

Candidate-set and method sensitivity are now retained for this leading cohort. They do not satisfy the missing evidence or human review gates.

  • independent exact model evidence missing
  • controlled measurement missing

What matters, what we know and what is missing

Open evidence report JSON ↗

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.

Primary real-world questionDelivered energy and usable capacity

Controlled delivered-energy testing with voltage, protocol and termination conditions.

Hands-on synthesisnot collected

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.

Specification rank#5

Inside the bounded published category method.

Stress-test range#3–#7

Across 15 factor-removal and weight-change scenarios.

Hands-on state: not collected

Hands-on gate: Resolve the exact SKU and cell configuration. Performance claims require controlled delivered-energy or output measurements; otherwise report nameplate values only.

Decision cruxes
Delivered energy

Nameplate capacity does not establish usable delivered energy at a stated voltage and load.

Sustained output and thermal behaviour

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.

The 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.
