Might try something like this. Same components under lots of brand names.
Has solar controller builtin, USB and 12V out as well as limited 120VAC.
Easy to carry and portable.

I cannot recommend highly enough the DIY solar forum. It to solar is what
the Elecraft forum is to ham radio, really!
The owner, Will Prowse, has a ton of youtube video's about DIY solar and has
"cookbook" type recommendations that would be stupid simple to put together.

What can you tell us about RF noise from the Morningstar charge
regulators when the wiring between panels, regulator, and battery is
very close to antennas? I'd

That can be fine if you don't need to operate

I second the GENASUN. And they have the advantage of being RF dead quiet.

For several years I have been using 5.5 AH (for KX3) or 25 AH (for K3)
LiFePo4 batteries, charging them with 1 or 2 60W portable folding solar
panels using GENASUN MPPT rf quiet controller. This controller is highly
recommended.

I finally installed a single 50 W, 12 V solar panel on the roof for light
backup purposes -- phone/pad/laptop/flashlight charging, natural-power use of
the KX2/KX3, etc.
Contact my friend Harry at h.niedec...@wirlnet.com (

have a smaller one too. In any case, he knows the lay of the land and what
is good and what is not. Tell him I sent you.
I use 12V LiFePO4s which keep the voltage up
I think a West Mountain Epic Powergate will meet your needs.

I finally installed a single 50 W, 12 V solar panel on the roof for light
backup purposes -- phone/pad/laptop/flashlight charging, natural-power use of
the KX2/KX3, etc. Connecting the panel directly to automotive-style USB
chargers works great when the sun is shining.
