Power-bank rankings
Every list sorts one explicitly defined manufacturer rating or a transparent calculation from sourced ratings. Each power-bank ranking has its own published formula and evidence record.
How BatteryRank reviews and scores →11 sourced models
Compare laptop power banks by their strongest wired USB-C output, with shared-port limits and dated manufacturer sources.
Formula: We rank by the strongest single USB-C output rating, highest first. Combined output across several ports does not count.
Open ranking →10 sourced models
Rank the documented single USB-C input ceilings of laptop power banks. Proprietary docks and combined inputs stay outside this comparison.
Formula: We rank by the highest documented wattage accepted through one standard USB-C input. Proprietary docks and multi-port inputs do not count.
Open ranking →13 sourced models
Compare explicit manufacturer watt-hour ratings against carrying weight. This calculated ranking excludes packs without a sourced Wh rating.
Formula: We divide rated battery energy (Wh) by pack weight (kg); higher ranks first. This compares stored energy per carrying weight.
Open ranking →8 sourced models
Compare compact phone power banks by their strongest wired USB-C output. Check device protocols and wireless limits separately.
Formula: We rank by the strongest single USB-C output rating, highest first. Combined output across several ports does not count.
Open ranking →4 sourced models
Compare outdoor packs with capacity labels from 9,000 to 11,000mAh by manufacturer-listed weight. Lower weight ranks first.
Formula: We compare outdoor banks labeled 9,000–11,000mAh by manufacturer-listed pack weight; lighter ranks first. Similar capacity labels do not establish equal usable USB energy.
