OnePlus is about to kick off April 28, 2026, with a bang. The company’s upcoming launch event in China isn’t just about its much-anticipated gaming phone, the Ace 6 Ultra. According to fresh teasers shared on Weibo, OnePlus is also preparing to drop two brand-new accessories that could change how you think about fast charging.
Meet the “Small Square Bottle” and “Small Square Bottle Pro” – a pair of compact power adapters that pack some serious wattage. While the names might sound quirky, the specs are anything but. OnePlus is clearly aiming to offer more than just phone chargers; these little bricks are built to juice up laptops, tablets, and even other phone brands thanks to wide protocol support.
Let’s break down everything we know so far.
The Pro Model: 100W Single-Port Powerhouse
First up is the 100W ‘Small Square Bottle Pro’ – a single-port USB-C adapter that, as the name suggests, delivers up to 100W of fast charging. But here’s the kicker: OnePlus has officially confirmed that this 100W rating isn’t locked to its proprietary SuperVOOC standard. Instead, the charger plays nicely with PD, UFCS, and QC 3.0.
That’s huge news for anyone tired of carrying separate bricks for their laptop, gaming handheld, and phone. In theory, you could use this single adapter to fast-charge a MacBook Air, a Steam Deck, or a non-OnePlus Android device without any proprietary handshake tricks.
OnePlus hasn’t shared the full spec sheet yet, but we already have a solid point of reference. Oppo recently released an identical 100W charger – same size, same output, same multi-protocol support. According to Oppo, the adapter measures just 56 x 33.5 x 33.5mm and weighs a featherlight 90 grams. That’s smaller than many 30W laptop bricks.
The only difference? OnePlus will offer its version in the brand’s signature red-and-white colorway. Oppo’s variant is more understated, but the OnePlus version should stand out nicely on your desk or in a travel bag.
Oppo’s 100W charger retails for CNY 229 (about $33) , so expect the OnePlus Pro model to land at a similar price point – possibly a tiny premium for the styling.
The Non-Pro ‘Small Square Bottle’: Dual Ports, 120W Single, 125W Total
If you need more flexibility, the standard “Small Square Bottle” might be your winner. This one features two USB-C ports and even higher peak output.
In single-port mode, the adapter can deliver up to 120W – enough to fast-charge a beefy gaming laptop or a high-end Android phone at warp speed. When both ports are active, the total output reaches 125W, intelligently distributed between the two connected devices.
Like its Pro sibling, this dual-port charger is also a rebrand – this time of the 120W GaN adapter Oppo launched recently. GaN (gallium nitride) technology explains how OnePlus fits so much power into such a small chassis. Expect support for PD, PPS, QC 3.0, and UFCS, making it one of the most universal fast chargers on the market.
For reference, Oppo’s 120W dual-port charger has a launch price of CNY 269 (roughly $39). OnePlus will likely match that, though bundling options with the Ace 6 Ultra could lower the effective cost.
If you’re planning to pair either charger with a high-wattage device, you’ll want a cable that can handle the juice. A high-quality 240W-rated USB-C cable is essential – especially for the 120W model. You can find a well-reviewed option like the Anker 240W USB-C cable (6-feet) on Amazon – click here to check the current price. It supports PD 3.1 and is built for future-proof charging.
What About the Ace 6 Ultra?
While the chargers are stealing the spotlight in these teasers, let’s not forget the main event. The OnePlus Ace 6 Ultra is positioned as a dedicated gaming phone. Rumors suggest it will feature a flagship Snapdragon chip (likely the 8 Elite Gen 2 or similar), an aggressive cooling system, and – you guessed it – support for those ultra-fast charging speeds.
It’s safe to assume the Ace 6 Ultra will work seamlessly with both new adapters, likely hitting peak wattages only OnePlus devices can achieve. But thanks to the multi-protocol support, even if you switch to another brand next year, these chargers won’t become e-waste.
Why These Chargers Matter (Beyond the Specs)
Most phone makers still ship chargers that only work optimally with their own devices. OnePlus (and Oppo) have been quietly changing that. The inclusion of UFCS (Universal Fast Charging Specification) is particularly noteworthy – it’s the Chinese industry standard designed to let different brands fast-charge each other’s phones.
With PD and QC 3.0 also on board, these “Small Square Bottle” chargers are essentially universal travel companions. The 100W Pro is ideal for minimalists who only carry one device at a time. The 120W dual-port version is perfect for road warriors juggling a laptop, phone, and earbuds.
And let’s talk size. A 120W GaN charger that fits in the palm of your hand? A few years ago, that would’ve required a brick the size of a VHS tape. Now it’s 90 grams and barely larger than a large ice cube. OnePlus clearly understands that portability matters as much as power.
Pricing and Availability
OnePlus hasn’t announced official pricing for the chargers yet, but Oppo’s identical hardware gives us a reliable benchmark:
| Charger | Ports | Max Power | Oppo Price (CNY) | Est. OnePlus Price |
|---|---|---|---|---|
| 100W “Pro” (single) | 1x USB-C | 100W | 229 (~$33) | $33–$36 |
| 120W (dual) | 2x USB-C | 120W/125W | 269 (~$39) | $39–$42 |
Both adapters will likely launch alongside the Ace 6 Ultra on April 28, 2026 – initially in China, with a global rollout to follow. Given OnePlus’s track record, expect international availability within a month or two after the China debut.
Final Thoughts: Should You Wait for These?
If you’re in the market for a compact, high-wattage charger that actually works with multiple devices, yes – these “Small Square Bottle” adapters look very promising. The Oppo versions have already received positive early feedback for their thermal performance and protocol compatibility. OnePlus’s red-and-white styling is just the cherry on top.
For current OnePlus users, the Ace 6 Ultra will almost certainly come with a proprietary charger in the box. But if you want a second adapter for the office, travel, or to charge your laptop as well, the 120W dual-port model is the one to watch.
And if you can’t wait until late April? The Oppo versions are already available in China, and international sellers will likely stock them soon. Otherwise, mark your calendar for April 28 – it’s shaping up to be a very interesting day for fast charging fans.
