ok so basically, i've been in the oneplus ecosystem for years and here is the deal with supervooc. honestly it is a bit annoying cuz standard power delivery (pd) chargers wont really cut it. you will likely only get about 18w or maybe 27w with a generic brick, which feels like a total crawl once youre used to that 67w speed. the phone basically needs a specific chip in both the charger and the cable to handshake for those peak speeds. if you wanna save some cash, my biggest tip is to look for oppo or realme branded gear. it is literally the same tech, just different branding, and it usually costs way less than the official oneplus store stuff. here is what i have been using to keep my open topped up on a budget:

• for the car, i definitely recommend the OnePlus+SuperVOOC+80W+Car+Charger&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus SuperVOOC 80W Car Charger. i actually found mine on sale for about $35. it hits peak speeds so i can get a huge chunk of battery back during a short 20 min drive.
• for cables, dont buy generic ones from the gas station. they highkey throttle the speed because they cant handle the high amperage. the OnePlus+SuperVOOC+Type-A+to+Type-C+Cable+150cm&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus SuperVOOC Type-A to Type-C Cable 150cm is around $15 to $20 and is actually durable enough for daily use.
• power banks are the hardest part. the OPPO+SuperVOOC+33W+Power+Bank+10000mAh&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OPPO SuperVOOC 33W Power Bank 10000mAh is a pretty decent budget option. it isnt the full 67w, but it is way faster than standard pd banks and usually runs under $45. anyway, hope that helps you out! just make sure the listing specifically says supervooc or it wont hit those fast speeds you want. gl!

Similar situation here

• I went through this last year when I first got my Open and was totally obsessed with getting those 67W speeds everywhere!! Honestly I was super cautious about using third-party stuff cuz I didnt want to mess up the dual-cell battery setup with weird voltage spikes or thermal issues. Basically, I spent way too much time comparing different setups and here is what I found from my own journey trying to save a few bucks: 1. Official OnePlus+100W+Car+Charger+vs&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus 100W Car Charger vs Oppo+80W+Alternative&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">Oppo 80W Alternative

I initially looked at the OnePlus+100W+Dual+Port+SuperVOOC+Car+Charger&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus 100W Dual Port SuperVOOC Car Charger which is fantastic but a bit pricey for my budget. Then I found that the OPPO+80W+SuperVOOC+Car+Charger&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OPPO 80W SuperVOOC Car Charger actually works exactly the same way.

• Pros: Both hit the peak 67W for the Open because they share the same proprietary SuperVOOC handshake protocol.
• Cons: The Oppo+one+is+sometimes+har&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">Oppo one is sometimes harder to find, but man, it really is a lifesaver for the commute. 2. Standard PD Power Banks vs Specialist Banks

I tried using my Anker 737 Power Bank PowerCore 24K and while it is a beast for my laptop, it only gave me like 18W on the Open. I eventually learned that if it doesnt say VOOC, it wont hit those high speeds. I ended up getting the OPPO+30W+VOOC+Power+Bank+2&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OPPO 30W VOOC Power Bank 2 for when I am out.

• Pros: Much faster than standard PD for these specific BBK-group phones.
• Cons: You still wont hit the full 67W on a portable bank, which is kinda a bummer tbh. 3. Long Cables: Official vs Generic

I tried a generic Baseus 100W USB C Cable thinking the 100W rating would be enough, but it only charged at a crawl. I ended up having to buy the OnePlus+SuperVOOC+Type-C+to+Type-C+Cable+100cm&linkCode=osi&------123456890?5422-20" target="_blank" rel="nofollow sponsored">OnePlus SuperVOOC Type-C to Type-C Cable 100cm because you literally need that 6.5A rated internal wiring for the fast charging to even kick in. So yeah, my experience was basically that staying in the official ecosystem is the only way to get those insane speeds safely. Itll feel like a snail if you try to use standard PD gear! Peace!

So basically the consensus here is that you either stick to the official gear or go with the sister brands like Oppo to get those peak speeds. Everyone seems to agree that heat and the dual-cell battery are the main things to watch out for if you stray from the pack. Not 100 percent sure but I think I heard someone mention that the latest SuperVOOC specs might be getting a bit more flexible with high-wattage PPS, but IIRC it still throttles heavily if it does not see that specific proprietary chip in the cable. As a bit of a DIY enthusiast who usually loves finding workarounds, I have noticed:

• Most third-party cables just cannot handle the specific pinout for the handshake
• Trying to rig up a non-certified high-speed setup usually just defaults to slow speeds anyway
• There is not much room for self-service or modding when it comes to the power delivery side Honestly, I am usually all for finding a cheaper way to do things yourself, but with the way these protocols are built, you are kind of locked in. If you try to force a custom charging solution that is not meant for it, you might end up needing a professional service for a motherboard or battery replacement. It is one of those cases where the DIY approach feels like way more risk than reward.

Honestly, I was super cautious about safety with my Open! Comparing:

• Official: AMAZING/Safe
• PD: Overheating risk
• Third-party: Sketchy

I strictly stay in-house now to protect my battery health!!

Would love to know this too
