About Liters Not Amps
Liters Not Amps is for drivers buying a portable lithium jump starter. The big number on the listing is peak amps. There is no single shared test that every brand must use for it, so a 4000 amp pack from one brand and a 2500 amp pack from another can claim about the same engine. The number you can use is the one next to it: the largest gas and diesel engine, in liters, that the maker says it will start. This site finds that number on each listing, adds headroom for cold weather, and points you to packs that fit your engine. We have not used these products. We read the listings and the owner review summaries on Amazon.
Who runs this site
Liters Not Amps is run by one independent publisher who also runs the sister guides listed at smart-buy-guides.pages.dev. We are not owned by, paid by or partnered with any brand we write about. Amazon is the only company we have an affiliate relationship with, and it has no say in what we write.
How picks are made
We choose every product from public information: the manufacturer's spec sheet and Amazon listing, safety certifications, warranty terms, and recurring themes in what owners report. We read the listing numbers closely, run them through the same math as the calculator on this site, and leave out products whose listings hide the numbers that matter. We only list products sold on Amazon. If a number on this site is a manufacturer claim, we label it as a claim.
We do not test products
We have not bought, used or tested these products, and we do not receive free samples. Nothing here is a hands-on review. When we describe what owners like or complain about, that is our own summary of recurring themes in public owner feedback, not our experience and not a quote.
How this site makes money
As an Amazon Associate I earn from qualifying purchases. When you click a link to Amazon and buy something, we may earn a small commission from Amazon. It costs you nothing extra. Commissions never decide which products we list or the order we list them in, and we do not accept payment for placement. There are no ads and no sponsored posts on this site.
Prices
We do not print prices because they change daily. Use the buttons to see the current price on Amazon.
Corrections
Listings change and we make mistakes. If you spot a wrong number, a dead link or a product that is no longer sold, tell us. We check every report against the current listing, fix confirmed errors as soon as we can, and change the "Updated" date on that page when we do. If a correction changes a recommendation, we say so on the page.
