Sources, estimates
and what we still need to verify.
Reviewed 1 November 2026. We keep published reference values, our modelling choices and unverified defaults separate. A source link supports only the field it is attached to.
One register, several kinds of evidence.
The calculator reads the same central register shown here. Our main UK appliance reference is the Centre for Sustainable Energy. It cannot validate every device variant, charging event or motor start. Manufacturer specifications and your own appliance measurements are needed for those.
- Reference-based: a published generic reference mapped to one of our presets; not a measured category average.
- Derived: a transparent calculation combining a source value with our own scenario.
- Assumption: an editable usage or modelling choice.
- Provisional: a prototype number without sufficient external evidence. It remains unverified.
The current catalogue uses source-checked UK station specifications. Archived demo fixtures are kept separate. Product specifications are manufacturer declarations, not our own measurements.
Appliance defaults, field by field
Prefer actual appliance labels or measurements. Charger output ratings do not tell us Wh per charge. For fridges, annual energy and compressor startup are different quantities. A PC power-supply rating is not its measured demand.

Phone charging: full charges, not hours.
Phone energy is estimated as the number of phones × full-charge equivalents per phone per day × backup hours ÷ 24 × watt-hours per full charge. One phone charged fully once per day over 48 hours therefore uses two full-charge equivalents. A daily half-battery top-up can be entered as 0.5 charges per day.
The timeframe scales the expected number of charges proportionally; it does not assume a phone charges continuously or round up to whole charging events. We then apply the same usable-battery and conversion-loss allowances as for other devices. Charging wattage is checked separately against simultaneous output requirements.
Our current energy-per-charge presets are provisional assumptions, shown in the field evidence above. Actual phone batteries and charging losses vary. Charging is modelled through an AC adaptor; direct USB charging is not separately modelled.
Calculation assumptions
Usable battery: 88%
Prototype usable battery allowance, not a measured universal station specification. Assumption, not a universal specification.
Conversion efficiency: 88%
Prototype AC conversion allowance; not validated by load/model. Device charger losses and inverter idle load are not separately modelled. Assumption, not a universal specification.
Output headroom: 20%
Editorial output headroom policy, not a certified safety factor. Assumption, not a universal specification.
How the calculation works
energy: Continuous: W × hours. Scheduled: W × hours/day × duration/24. Cycling: W × duty fraction × duration. Charging: Wh/charge × charges/day × duration/24.
losses: Nominal capacity = delivered Wh / (usable fraction × conversion efficiency). Do not apply losses twice. Idle draw is omitted.
output: All selected loads are assumed concurrent. Apply configured headroom to continuous W and combined startup W.
tiers: Filter technical estimates first. Budget = lowest internal synthetic price; Best Value = lowest synthetic price/Wh among remaining; Premium = highest remaining capacity. These are demo sorting rules, not review scores.
runtime: Capacity × usable fraction × efficiency / average delivered W. Repeating usage assumption; whole-hour rounding is a display convention, not accuracy.
The general power/time relationship is supported by CSE. Our daily usage, loss factors, concurrent-start rule and tier ordering are our own choices.
