I have been through a lot of chargers. Boxes of them. Some melt, some lie about their wattage, and some are genuinely good. Here are three that crossed my desk this week from the Chinese charging ecosystem.
Huawei 100W Bingtang (Sugar Cube) Charger
Huawei released this on May 19 at a预售 (pre-sale) price of 299 RMB. It is a single USB-C GaN charger measuring 44 x 44 x 31 mm and weighing 88 grams. Those are the specs Huawei publishes, and I have no reason to doubt the dimensions. The selling point is protocol compatibility. It supports Huawei SuperCharge (SCP), PD 3.0/PPS, QC 2.0, and UFCS. The UFCS certification matters because it means this charger can actually fast-charge phones from other Chinese brands. Xiaomi. OPPO. vivo. Not just Huawei devices. That is a shift worth noting.
The charger comes with a 1-meter 6A C-to-C cable that has an E-Marker chip. Smart. Non-folding pins, which I prefer. Folding pins break.
OPPO SUPERVOOC 120W Super舱 Power Bank
OPPO launched this in April at 299 RMB. 15000mAh capacity. One USB-A and one USB-C port, both capable of 120W solo. Dual-port output drops to 30W + 65W. Dimensions are 105 x 70 x 29 mm, weight 310 grams. It uses what OPPO calls the Ice Shield (冰盾) safety cell, and it is the first power bank to pass China’s new mandatory national standard GB 47372-2026, which goes into effect April 2027.
What caught my eye is the “OPPO Power Bank Assistant” software. Plug it into a computer and you can check cycle count and cell health, like you would on a phone. That is useful. Most power banks are black boxes. You guess when they are degrading. OPPO is giving you data.
The bank also has a QR code and SN for traceability. This is a direct result of the new standard. Every cell can be tracked back to production. I like that. It is the kind of thing that should have been mandatory years ago.
Baseus EnerFill FH22 100W GaN
Charging Head Network (充电头网) did a full teardown on this one, and the details are worth repeating. The FH22 measures 48.22 x 36.25 x 36.32 mm and weighs 107.7 grams. That is small for 100W. Baseus claims 65% volume reduction over traditional 100W chargers. The teardown confirms they achieved this with a 3D stacked PCB and heavy thermal potting compound. The main GaN controller is a Dongke DK8712BD in an asymmetric half-bridge architecture running up to 800 kHz. The protocol controller is an SW2325P with a built-in 32-bit MCU. The thing supports PD 3.2, PPS, AVS, UFCS 2.0, QC 5, and Apple 2.4A.
This is an example of the Shenzhen supply chain working well. Baseus does not make chips. They buy from Dongke and Zhirong and assemble. The result is a 100W charger that fits in a pocket. Street price on Taobao is around 149 RMB.
A few things worth watching. UFCS adoption crossed 189 certified products as of May. The new power bank standard is forcing real engineering changes. And GaN chargers keep shrinking. The Baseus FH22 is not the smallest 100W on the market, but the teardown shows honest construction. No empty space inside. No fake components. That counts for something.
