I bought a portable 30W solar panel to get ready for the apocalypse (feddit.uk)

I'm only half kidding. I'm a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.

Not like this solves the issue. 30 watts (under ideal conditions) isn't much but it's a start.

300 watts would need at least two full size panels.

    So you mean 30 watts pr panel? This is s 100 watts setup that Amazon delivers. Half of your panels and portable. It costs a bit more, but not much.

    https://www.amazon.com/DOKIO-Monocrystalline-Foldable-Charge-Controller/dp/B0748FYFSK/

    I can get one panel that gives me 30 watts for the same price : https://eur.vevor.com/solar-panels-c_13594/vevor-30w-12v-solar-panel-battery-charger-solar-battery-trickle-charger-maintainer-with-built-in-smart-controller-3-connection-cables-ip67-waterproof-portable-for-rv-car-motorcycle-boat-van-camper-p_010231793059

    This is 50w for half your price ( seems too good to be true almost) https://www.amazon.com/Monocrystalline-Portable-Foldable-Charger-Camouflage/dp/B0DDQGKGQ1/

    Im not saying these are the best. Im saying 30w is very low these days and og you want a post apocalypse setup, 30w claimed it's not 30w given and there are better options out there for similar-ish price

    This claims to be 250w(!) with one flexible panel and controller...! https://www.joom.com/nb/products/68f8ddd4ed3bfa014c61a351

    I seriously need to upgrade mine!!!!😆 I have portable double panel that is 10+ years old and should give 75w, but i get max 35 from it. Im sure i need to update some wiring to thicker cables. It cost me about 5 times your setup.

    The dimensions of that first panel are more than double compared to mine so obviously it has a higher output. I intentionally wanted one that fits into a backpack. Whatever output this produces is vastly better than the 0-watt charge capability I had before. I'm well aware that spending more money and getting larger panels would give me more output. However, it's for charging small handheld electronics - not for running a fridge.
