How small? The ones I'm finding on the internet all have their own internal batteries and look to be about 2 lb / $50. They are handy USB battery backups, and I'll probably buy one, but if you have one that is lighter weight and skips the internal battery, I'd like to know the brand and model. There are less expensive and lighter internal battery ones, but the reviews don't make them look reliable.I have a small air compressor that plugs into the battery-tender pigtail for this reason.
I'm considering this one unless someone has something better: https://www.amazon.com/dp/B09N74R7P...colid=ZQ9TKRSFS4FO&psc=1&ref_=lv_ov_lig_dp_it
