About powerbank.energy
A spec comparison for portable batteries, wall chargers and charging cables — 450 power banks, 306 chargers and 149 cables from 11 brands, in one sortable table each, so the numbers can be compared directly instead of opening a dozen tabs.
Where the numbers come from
Every spec on this site is taken from the manufacturer’s own product page — not retyped from retailer listings, review sites or marketing roundups. Each product page carries a Source link to the exact page its row was read from, so any value here can be checked against the original in one click.
The brands covered today:
- Anker
- Aukey
- Baseus
- Belkin
- CUKTECH
- INIU
- Mophie
- Nimble
- Ugreen
- Varta
- Zendure
A product missing from a table hasn’t been judged and rejected — it just isn’t in a catalog that gets read yet.
How current they are
The catalogs are re-read twice a month, on the 14th and the 28th. Every product page shows its own First seen and Last seen dates, so the age of any row is visible rather than assumed.
Prices are the manufacturer’s own list price in the currency their site quoted, as of that last read. Shops routinely sell for less, and sales move faster than a twice-monthly scrape — treat the price as a reference point, not a live quote.
Why some fields are blank
A dash (—) means the manufacturer doesn’t publish that spec, not that the value is zero. Gaps are never filled with estimates, inferences or numbers borrowed from a similar model: showing the gap is more useful than a confident guess, because a plausible wrong number is the one thing you can’t check.
Where a spec was pulled out of prose rather than a spec table, the product page says so under Spec confidence, and rows that need a human to look at them are flagged outright.
Independence
No manufacturer pays to be included, and none can pay for placement. Every table sorts and filters on the specs alone, and the ordering is whatever you pick — there is no house ranking, no sponsored row and no editorial thumb on the scale.
The Buy buttons run an Amazon search for the product in your selected marketplace. They are not affiliate links and earn this site nothing today; if that changes, this page will say so before it does.
Links out to a manufacturer’s site may redirect based on your region or on whether they still stock the product — where that link ends up is their site’s decision, not this one’s.
Corrections
Specs get misread, and manufacturers quietly change published figures. If a number here disagrees with the source page, the source page is right and this site has a bug worth fixing.
