Usable capacity

100% of this battery’s nominal capacity is usable, 10 kWh in the scored configuration.

10 kWh usableScored configuration: X1-P6K-B10-S. Published range 5–30 kWh.

No reserve is withheld at the stated depth of discharge.

At a sourced 100% depth of discharge the usable and nominal figures are the same number, so no separate nominal capacity is stated.

No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

The blackout score is a standalone benchmark of outage resilience only - it re-weights sourced specs already scored in this product’s pillars (backup tier, switchover, surge strength, backup power, off-grid recharge) and never affects the overall score. Dots show the full battery fleet; the marker is this product.

Verification & sources

Market context

Global evidencechange in the site menu

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. The score stays fixed to the named Australian approved configuration rather than inheriting the largest stack. Hybrid throughput is withheld where the warranty table does not reproduce the approved HC model suffix. Scored model: X1-P6K-B10-S · checked 2026-08-02. Evidence.

Strong evidence coverage

29 of 29 scored criteria link directly to a published source.

Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Record revision. X1 AC-coupled datasheet, current Australian X1 and Power Dock Pro product page, and AU warranty effective 2026-03-23 re-audited 2026-08-06. First-market DE overlay review 2026-08-31: official German catalogues recorded; Australian and United States overlays and scores unchanged.

    DE Support Note

    Before
    Not previously recorded
    After
    The scored identity is AC-coupled X1-P6K-B10-S. Anker's German X1 catalogue describes hybrid single-phase 3.68-6 kW and hybrid three-phase 5-12 kW families. German VDE-AR-N 4105 support articles name the hybrid three-phase system and the hybrid single-phase X1-H(3.68-6)K-S power module. The German warranty table names X1-P6K-S among many SKUs but does not name X1-P6K-B10-S, and a warranty-table row is not a German AC-coupled sale path. Hybrid X1 H-series identities are not transferred onto this AC-coupled record.
