MOSWAG Car Charger, Invisible Cigarette Lighter USB Adapter [All Metal & Mini], 2 Port Car Adapter, QC3.0 Dual Port Cigarette Lighter for iPhone 17 16 Samsung S25 Ultra Piexl 10 and More

I see. Well in the spirit of DIY electronics, you could buy a 12V-to-5V USB adapter and solder the old pump wire to the adapter. You can get voltage converters easily online or in electronics stores, or you can grab one that is made to charge a phone in your car in any gas station, and take that apart. eg:https://www.amazon.com/HiLetgo-DC-DC-Module-Charger-Arduino/dp/B01HXU1C6Uhttps://www.amazon.com/MOSWAG-Charger-Cigarette-Lighter-Charging/dp/B0DG2TQ4R9 Again, just be sure it can supply at least 1 amp. More is fine, less is not.
