Corrections
Where a number here is wrong — a capacity, a continuous output, a connector designation, a charging temperature, an ingress code, a price band, or a description of how something behaves — say so. It gets checked, corrected, and the page records what changed. Nothing else you could send is worth as much, and nothing else is handled as quickly.
Questions about the equipment
Everything is read, and as much as possible is answered. A question that keeps arriving usually ends up as a page of its own, where it reaches far more people than a private reply ever could.
Manufacturers and agencies
Datasheets, manuals, charging profiles, compatibility lists and corrections from makers are genuinely useful and do get used. What will not happen: coverage is not for sale, a loaned unit buys no write-up, and nothing here is sponsored. Shipping us a product reserves no position in any list, and offers along those lines are not replied to.
The address
Messages go to buissonjeanbenoit9 (at) gmail.com, an inbox with exactly one reader — which is why a reply is sometimes several days coming.
Please send nothing confidential. This is an editorial site and not a support desk: warranties, repairs, firmware trouble, returns and orders belong to the seller or the manufacturer, and we have no way to deal with them.
