Instead of the sane approach of specifying 5, 9, 12, 15, and/or 20 volts and the amperages, products insist on listing every model of device in existence instead.
Most will do 12V, but I always want to make sure it’ll power my laptop (20V) as well.
A big thank you to reviewers who post images of the actual products where it shows the relevant info in one short line on the labels:
e.g. PD Output: 5V=3A, 9V=3A, 12V=3A, 15V=3A, 20V=3A
That looks a bit overkill for camping, but yeah, definitely what I’m after / trying to achieve. I guess I could justify the expense if I set it up at the house between trips. Actually…that’s not a bad idea.
Not for this, but I’m eventually looking for a 48v lithium charger for solar panels. The ones I looked at weren’t terribly expensive but were designed for larger systems than what I have (I just want to safely charge my 48v 20AH multipurpose ebike battery from solar)
It’s in storage since I moved a few years ago, but I had a 1.2 KW ground mounted grid-tie setup at my old house (basically a proof-of-concept before moving to something bigger). Looking to dig that out for either a bigger grid tie setup or possibly feeding something akin to a PowerWall. Probably going with LiFeP04 for safety / peace of mind reasons.
Cool guide! Skimmed it, but saved it for later to read through in more detail when I’m not on mobile.
To charge your 48v ebike battery you will probably be looking at a proper 48v solar charge controller from victron then. They are expensive but worth it. dont want to fry your battery with no-name brand junk pwm advertising as mppt. , Though you can get away with the cheaper 48v 100/20 or 100/10s versions if you want to save some cash. a single 12v solar panel wont cut it though you need a couple 200w or 400w foldups chained to add voltage up to around 48v to charge a big battery effectively.
That one’s actually what I’d consider affordable considering something like this beast (solar inverter / charger) was what I was originally looking at.
