The Notorious Tre` All Messages By This Member #115776 I really like the RoyPow. I chased one down refurbishes then my brother, who is also a ham, apparently ran into them independently and got me another one for christmas to use with my FT817 and other handheld gear. It has one USB-C in or out (used to charge or can be connected?to a device while not charging) and two high capacity standard USB ports, a 12v/5a coaxial output and a 12v/10a accessory style plug output. rated at 86Wh I used one in the deer blind this year to occasionally power my 12v electric blanket.?

Greg D All Messages By This Member #115775 开云体育 Mmmm, careful.? At 88 watt-hours, that's barely more than 7ah at 12v, not counting internal conversion losses.? The inverter may be able to source 100 or 300 watts, but not for long.? 300 watts from an 88 watt-hour battery will drain it in something like 15 minutes.? Of course the FT-817/818 draws considerably less - you'd likely get 5+ hours of use - but there's no Tardis-derived magic here.? Start plugging other stuff in, and the run time can drop very quickly. When looking at these "Solar generators", the important spec to look at is the watt-hour rating of the battery.? The AC output spec is just for the inverter; it's a limit for how much (peak) power can be drawn, not for how long. Greg?

Joseph Wonoski All Messages By This Member #115771 Two ordinary 5 volt power banks of sufficient ah ratings wired in series creates 10 volts which is about the ideal voltage for the radio.
