Is your power bank compatible with the proprietary fast-charging protocols of major smartphone brands?

In today's multi-device environment—smartphones, tablets, laptops, and for some, multiple handsets—the proliferation of proprietary fast-charging protocols across brands (Huawei, Honor, OPPO, Vivo, Xiaomi, Apple, Samsung) creates significant user inconvenience. This often necessitates carrying multiple, incompatible chargers. Our goal is to consolidate this complexity, enabling a single power bank to efficiently charge all devices, including laptops.

I. Huawei / Honor Fast Charging Protocols

1. Huawei/Honor Proprietary Protocols (SCP/FCP):

• FCP (Fast Charge Protocol): The earliest proprietary standard at $18\text{W } (9\text{V}/2\text{A})$.

• SCP (SuperCharge Protocol) 1st Gen: $22.5\text{W } (5\text{V}/4.5\text{A } \text{or } 4.5\text{V}/5\text{A})$. Focusing on low-voltage, high-current direct charging. This is the most common protocol opened up to third-party accessories.

• SCP 2nd Gen: Max $40\text{W } (10\text{V}/4\text{A } \text{MAX})$. High-voltage development. Incompatible with 1st Gen.

• SCP 3rd Gen: Max $66\text{W } (11\text{V}/6\text{A } \text{MAX})$. Compatible with 2nd Gen $40\text{W}$. Continued focus on increased current.

• SCP 4th Gen: Max $100\text{W } (20\text{V}/5\text{A } \text{MAX})$, including $88\text{W } (20\text{V}/4.4\text{A})$. Achieved by further increasing voltage. Compatible with 3rd and 2nd Gens.

2. Huawei/Honor Compatibility (Public Protocols):

• UFCS (Universal Fast Charging Specification): An emerging unified standard, currently supported symbolically at $\approx 33\text{W}$ (e.g., Mate70 series).

• PD (Power Delivery): Symbolically supported at $18\text{W } (9\text{V}/2\text{A})$.

• PPS (Programmable Power Supply) - Honor Exclusive: Honor devices often offer robust PPS support, ranging from $50\text{W}$ to $100\text{W}$, which is highly advantageous for third-party charging solutions.

II. OPPO / OnePlus / Realme Fast Charging Protocols

1. Proprietary SuperVOOC/VOOC Protocols (SuperVOOC/SuperDart/Warp):

OPPO's core technology, leveraging a dual-cell battery design and charge pump to reduce voltage on a single cell while maintaining high charging speed.

• VOOC (Dash/Warp/Dart): Max $30\text{W } (5\text{V}/6\text{A})$. Early low-voltage, high-current standard.

• SuperVOOC (SuperDart): The primary protocol with two main generations:

  • Gen 1 (10V-11V Series): $33\text{W}$ up to $150\text{W}$ (e.g., $65\text{W } (10\text{V}/6.5\text{A})$, $150\text{W } (11\text{V}/13.7\text{A})$).

  • Gen 2 (20V Series - Primarily OnePlus/Realme): $150\text{W } (20\text{V}/7.5\text{A})$, $240\text{W } (20\text{V}/12\text{A})$.

2. Compatibility (Public Protocols):

• UFCS: Limited support, typically below $44\text{W } (11\text{V}/4\text{A})$.

• PPS: Recently supported by flagship OPPO models, often restricted to $33\text{W } (11\text{V}/3\text{A})$, with select models up to $55\text{W}$.

• PD / QC2.0: Symbolically supported at $18\text{W } (9\text{V}/2\text{A})$.

III. Vivo / iQOO Fast Charging Protocols

1. Proprietary VFCP (Vivo FlashCharge Protocol):

Similar development path to OPPO, using dual categories of voltage/current profiles.

• FlashCharge: Max $22.5\text{W } (4.5\text{V}/5\text{A})$. Older standard, largely discontinued.

• SuperFlashCharge:

  • 10V-11V Series: $22.5\text{W}$ up to $90\text{W}$ (e.g., $66\text{W } (11\text{V}/6\text{A})$).

  • 20V Series: $66\text{W}$ up to $200\text{W}$ (e.g., $200\text{W } (20\text{V}/10\text{A})$).

2. Compatibility (Public Protocols):

• UFCS: Limited support, typically below $44\text{W } (11\text{V}/4\text{A})$.

• PPS: Historically strong, supporting up to $100\text{W } (20\text{V}/5\text{A})$. Newer models have seen a trend toward reduced support, sometimes down to $55\text{W}$.

• PD: Symbolically supported at $18\text{W } (9\text{V}/2\text{A})$.

IV. Xiaomi / Redmi Fast Charging Protocols

1. Proprietary/Semi-Proprietary MiPPS (Mi Turbo Charge):

Xiaomi initially relied on Qualcomm QC, but since the Mi 9, it developed a semi-proprietary protocol by modifying PPS, labeled as MiPPS. This allows for excellent backward compatibility across its various power levels:

• MiPPS Power Levels: Ranging from $30\text{W } (10\text{V}/3\text{A})$ up to $120\text{W } (20\text{V}/6\text{A})$. Higher wattage chargers generally maintain compatibility with all lower MiPPS power levels. Examples include $67\text{W } (11\text{V}/6.1\text{A})$ and $120\text{W } (20\text{V}/6\text{A})$.

2. Compatibility (Public Protocols):

• PPS: Since MiPPS is a modified version, generic PPS is typically limited to a symbolic $\approx 27\text{W}$.

• PD: Max $15\text{W } (9\text{V}/1.67\text{A } \text{or } 5\text{V}/3\text{A})$.

• QC: Supports QC3.0 up to $27\text{W } (9\text{V}/3\text{A})$ and QC2.0 up to $15\text{W } (9\text{V}/1.67\text{A})$.

V. Apple / Samsung Charging Protocols

• Apple: Known for strict adherence to standards, primarily PD (Power Delivery). Apple devices typically support PD charging up to $30\text{W}$.

• Samsung: The proprietary AFC (Adaptive Fast Charging) protocol is less common now. Current flagship models support the public PPS protocol up to $45\text{W}$, which is ideal for seamless integration with third-party accessories.

Conclusion: The Need for a Unified Power Solution

The market is fragmented. Most generic power banks can only meet the modest PD charging demands of Apple and basic PD/PPS needs of some Samsung devices, failing to deliver the "original speed" fast-charging experience for high-powered Huawei, OPPO, Vivo, and Xiaomi phones, let alone provide sufficient power for modern laptops.
