12v 4A LiFePO4 Battery Charger, AC-to-DC (DC-Plug)

Everything they sell is high quality at a reasonable price!

Fast shipping; after charging overnight I tested it for ability to power Yaesu FTM-300D for power, noise, and drain. While I did not talk for very long as this was an impromptu initial test;, I handled the QSO without problems. The distant end could not tell the difference between being on my vehicle battery or my Bioenno battery. Full quieting and clear transmission both ways. Coming up March 25th & 26th I am volunteering to provide comms in support of a bike race and will put it to the full test for how long it last.
