Yo, congrats on the Nord 4! It is such an amazing phone, seriously, you are gonna love the speed once you get the right brick. I had the exact same issue when I got mine and was so annoyed! OnePlus uses this special tech called SUPERVOOC, so basically your old Samsung charger is only gonna trickle charge it because it does not speak the same language as the phone. Most standard chargers just wont work for fast charging here. To get those crazy fast speeds, you really need a charger that supports that specific protocol. I tried a few generic ones from Amazon and they were total rubbish, honestly. If you want to stay safe and fast, stick to the official stuff or sister brands. Here is what you should look for to get that 0 to 100 percent in like 30 mins:

• The absolute best is the OnePlus+Supervooc+100W+Dual+Port+Power+Adapter&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus Supervooc 100W Dual Port Power Adapter. It is a bit pricey but handles the Nord 4 at max speed!
• If you want to stay closer to your 30 quid budget, look for the OnePlus+Supervooc+80W+Power+Adapter&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus Supervooc 80W Power Adapter. It is still insanely fast and much safer for the battery than some random cheap brand.
• If you really want a third party one, the OPPO+80W+Supervooc+Flash+Charger&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OPPO 80W Supervooc Flash Charger works too since they use the exact same tech as OnePlus. Dont waste your money on standard PD chargers because they wont hit the high speeds. Just grab the official 80W or 100W one and you will be mind-blown by how fast it charges! Its life-changing not having to wait hours anymore...

Like someone mentioned, these proprietary speeds are a real pain. I wasted way too much money on cheap bricks over the years that promised fast charging but barely hit 10W. Turns out the cable is just as important as the plug.

• always check the cable rating
• make sure it supports PPS The UGREEN Nexode 65W USB C Charger is my go-to. It wont hit 100W, but its way faster than that old Samsung one.

omg you guys are so right about the cables, they literally make or break the whole thing!! i totally agree with what everyone said about the proprietary tech being a total headache to deal with. honestly tho, i found the most amazing breakdown on youtube when i was looking for my own setup. just search nord 4 charging speed test or something similar and its like one of the first few videos that pops up. there is this one creator who tests all the different bricks with a power meter to see which ones actually hit those crazy speeds without overheating or being unsafe. its way better than just guessing and potentially ruining your battery life right after buying it! the nord 4 is such a fantastic phone so you definitely dont want to mess it up with a dodgy plug... definitely check reddit too because there are some massive threads about this exact thing.

Good to know!

Late to the party but this whole thread is 💯. Glad I found it.

Quick reply while I'm on my break. In my experience, you don't actually need the official brick if you understand how power delivery works, though you wont get the absolute max 100W speeds.

If you want to stay under that 30 quid limit, these are reliable alternatives I've used:

• Anker 715 Charger Nano II 65W
• UGREEN Nexode 65W GaN Wall Charger
• Baseus 65W GaN5 Pro Fast Charger I've tried many different brands over the years and haven't had any issues with battery health. These modern chargers have built-in protection to prevent overcharging. Just make sure you're using a high-quality cable, otherwise the charger wont be able to do its job properly.
