How it was worked out

    What this does and doesn't tell you

    • Most power stations give less usable energy than the label. Leave a 10 to 20% reserve.
    • Lithium-ion tool packs can short, overheat and catch fire if they're damaged, wired wrongly or charged on the wrong charger. Only use the maker's charger for the pack.
