Power banks are rarely the story at a smartphone launch.
OnePlus is trying to change that on April 28, when the 120W SuperVOOC 2.0 Flash Charge Power Bank
debuts alongside the
Ace 6 Ultra in China. At 120W output and 15,000mAh capacity, it's a credible companion device — not just a bundled accessory footnote.
Summary
- 120W maximum output: Matches the Ace 6 Ultra's charging speed, enabling 30 minutes of charging to reach 68% on the smartphone.
- 15,000mAh capacity: Rated to charge the Ace 6 Ultra 1.5 times from a full power bank.
- First to use OPPO Ice Shield safety cells: Designed to meet new national safety standards with stable operation under challenging thermal conditions.
- Excimer laser skin-friendly surface: Premium tactile exterior finish consistent with the Ace 6 Ultra's design language.
- April 28 China launch, Accelerated Red color: Debuting alongside the Ace 6 Ultra as a coordinated ecosystem release.
The Output: 120W That Actually Means Something
Most power banks advertise headline wattage that requires specific conditions — a particular cable, a compatible protocol, and a phone that actually supports it. The 120W figure on the SuperVOOC 2.0 is directly tied to the Ace 6 Ultra's own 120W SuperVOOC charging standard, which means the real-world number isn't theoretical. The confirmed data point — 68% charge in 30 minutes — is the figure that matters for buyers evaluating it as a daily companion device.
The 15,000mAh capacity delivering 1.5 full charges for the Ace 6 Ultra is also worth noting. The Ace 6 Ultra carries an 8,600mAh battery, making the math consistent. That means most users can count on one full charge plus a meaningful top-up before the power bank needs replenishing. For a device launching at the premium accessory tier, that's a reasonable output-to-capacity ratio — particularly for a unit small enough to carry daily.
The Ice Shield Cell: Safety First at High Power
The OPPO Ice Shield safety battery cell is the technology story inside this power bank. It's the first time this cell design has appeared in a OnePlus-branded product, and it's built specifically to manage the thermal stress of sustained 120W output. High-power portable chargers have historically struggled with heat management — the Ice Shield cell addresses this directly, meeting China's new national standards for safety performance at high wattage. Stable operation under challenging conditions is a meaningful promise for a device that users may be charging in warm environments or inside bags.
Design: Premium Feel, Coordinated Aesthetic
The excimer laser surface treatment gives the power bank a skin-friendly grip that resists fingerprints and provides a tactile quality usually associated with flagship smartphones rather than accessories. The Accelerated Red colorway is a deliberate tie to the Ace 6 Ultra's gaming identity. It's worth noting — as Gizmochina reported — that this power bank shares its core hardware with an existing Oppo model. That's not necessarily a disadvantage: the Oppo equivalent has an established safety track record, and the OnePlus branding brings it into the SuperVOOC ecosystem with consistent protocol support.
