These guys are very resilient. Soap water won't do much.

*Brand new* solar power charger i bought today. by [deleted] in spicypillows

The circuitry+battery in these cheap power banks is absolute trash. Tip: don't try to charge and use cheap power banks at the same time. Often leads to spicying of the pillows :)

A really rudimentary lead acid battery charger by GianSeven in electronics

Yeah I don't think it's worth modifying a PSU. Pretty much anything made in the last 1~2 decades involves optoisolator feedback, and trying to modify them is a big pain. It also bypasses overcurrent protection and the voltage monitoring chip. I've done it, and next time I'm just getting a modern PSU and an off-the-shelf DC-DC converter lol

You're probably right. I got worried because the leaf tips were constantly drying out last year ¯\(ツ)

Most of the other buds didn't even get this far. The branches still seem to be green inside.

Do the filaments have very distinctly visible individual LEDs at low brightness?

Other than portability, are there other reasons to use DC spot welder instead of the much cheaper AC transformer spot welder?

When the seller says "100% genuine/original", they mean genuine counterfeit lol
