Honestly, finding one dock that safely handles both PS4 and PS5 controllers is a total nightmare. Most of those universal stands are just cheap plastic shells with zero voltage regulation, and unfortunately, that is exactly how you end up with a dead DualSense. I learned the hard way that trying to save 20 bucks on a combo unit isnt worth the risk of frying a 70 dollar controller. ngl, those hybrid designs are usually the biggest fire hazards because the board has to step down power for two different connector types. If you want something that actually lasts and wont burn your house down before the tournament, here are the ones I keep around:

• NexiGo PS5 Controller Charging Station with 3-Hour Fast Charging is my go-to for the DualSense. Its got a vertical design that is super stable, and the built-in protector chip actually works to stop the current once the battery hits 100%.
• HyperX ChargePlay Duo for PS5 DualSense Controllers is another solid choice. Its heavier than it looks so you wont knock it over when you are in a rush between matches.
• For your legacy pads, you really should just get a dedicated PowerA DualShock 4 Charging Station for PlayStation 4. Trying to mix the different charging ports on one cheap circuit board is usually why they overheat. Just get two separate compact stands. Its slightly more desk space but way safer for your gear, and they usually ship next-day if you use a major retailer... definitely worth the extra few bucks to avoid another meltdown.

Man, that overheating thing is terrifying. I went through the exact same thing a few years back with a cheapo stand that basically fused my DS4 to the plastic. Not fun. Honestly, after testing a dozen setups over the years, I stopped messing around with knockoffs. For your PS5 pads, you really should just grab the Sony PlayStation 5 DualSense Charging Station White. It uses the click-in pins at the bottom instead of the USB-C port, which is way more stable and has legit overcharge protection so it wont cook your battery. Since you need to charge both gens, look at the OIVO PS5 and PS4 Controller Charging Station Dock. It is one of the few that actually has specific slots for both types without being a total fire hazard. Its got a tiny footprint and usually arrives super fast. Tbh, spending the extra ten bucks for a brand that actually cares about voltage regulation is worth it to avoid another fried remote before your tournament.

Saw this thread today and it reminded me of my own disaster. Last year I tried a cheapo block that got so hot it smelled like burning plastic... definitely a close call. You might want to consider just sticking with PowerA. They are usually pretty reliable for the price. Be careful with those multi-system docks tho, they often skip the safety features so you wont kill your pads.

• You are so lucky your house didnt burn down!! Safety is literally everything with these expensive controllers so I am totally with you on needing something reliable that has real overcharge protection!
• Honestly finding something compact that fits both systems is the dream, just make sure you look for stuff that mentions UL certification because it makes a huge difference for peace of mind and wont fry your hardware.
• Local tournaments are seriously the absolute best though!! I remember hosting a massive fighting game night at my place last summer and it was such a blast until things got out of hand.
• Someone brought this incredible homemade buffalo chicken dip that was so spicy I think I actually lost my taste buds for a week, and then my dog somehow managed to eat a whole plate of spicy wings while we were mid-match...
• We spent like four hours the next morning just trying to get the buffalo sauce smell out of the rug and the couch cushions lol it was a total disaster.
• Anyway sorry kinda went off topic there but good luck with the tournament!
