Do all chargers have the same transmission?
No. Chargers do not transmit power in the same way. They differ in connectors, voltage and current limits, and the negotiation protocols that tell a device how much power to take. That means not every charger will deliver the same speed or work with every device without compatibility considerations.
Understanding why this matters helps explain why a charger that works great for one smartphone may not deliver the same performance for another, or why a laptop charger looks very different from a phone charger. The landscape spans wired and wireless methods, and it’s shaped by evolving standards, brand choices, and regulatory moves in key markets.
Wired charging standards
Wired charging relies on a physical connector plus a handshake that sets how much voltage and current are allowed. The industry has coalesced around a few dominant standards, but there is still fragmentation—especially when mixing brands or using older devices.
Dominant wired standards
Below is a snapshot of the main families you’ll encounter when you plug things in. The list reflects how power is negotiated and delivered, not just the connector itself.
- USB-C Power Delivery (PD) with USB-C connectors: negotiates voltages from about 5V up to 20V (and newer iterations extend beyond, under PD 3.1) with currents that can reach several amperes. This is the backbone for most modern phones, tablets, and many laptops.
- Programmable Power Supply (PPS) within USB-C PD: part of the PD standard that lets the charger adjust voltage in finer steps to match a device’s needs, helping optimize charging speed and efficiency.
- Qualcomm Quick Charge (QC) and similar fast-charging protocols: widely used on many Android devices, these protocols negotiate higher voltages (for example 9V, 12V, 20V) to speed up charging on compatible phones.
- Proprietary fast-charging technologies: brands such as Samsung Adaptive Fast Charging, OnePlus Warp Charge, Oppo VOOC, Huawei SuperCharge, and others. These often require both charger and device to support the same protocol for optimal results.
- USB Battery Charging (USB-BC) and basic charging ports: newer devices mostly rely on PD or proprietary fast-charging schemes, but older or budget devices may still use simpler charging profiles.
While most current devices can negotiate a fast charge with the right USB-C PD or compatible protocol, exact speeds depend on device support, cable quality, and charger capability. The trend is toward higher power delivery via USB-C PD, with newer PD iterations enabling higher maximums for laptops and high-end devices.
Wireless charging and other transmission methods
Wireless charging replaces a plug with electromagnetic transmission. The most widely adopted standard is Qi, but there are other approaches and brand-specific implementations that can influence performance and compatibility.
Wireless standards and practical differences
Here is how wireless power transmission typically works and what that means for users:
- Qi wireless charging (inductive): The standard used by most smartphones and chargers today. Power levels commonly range from about 5W to 15W for typical phones, with higher-end setups offering faster wireless charging in some cases. Efficiency depends on alignment and distance between the transmitter and receiver coils.
- AirFuel and other non-Qi approaches: A smaller subset of devices and accessories use alternatives or legacy wireless charging methods. Qi has become the dominant consumer standard, but there are niche implementations in use in some markets.
- MagSafe and other branded wireless formats: Apple’s MagSafe uses a Qi-compatible framework with a magnetic alignment system, delivering up to around 15W on compatible iPhones. Other brands have their own fast wireless charging concepts that still rely on Qi-compatible negotiation for power.
Wireless charging generally offers convenience at the expense of maximum speed and consistency. It is typically slower than wired charging, though advances continue to push the capability higher on certain devices and pads. Alignment, case materials, and pad quality all influence performance.
Regulatory moves and consumer impact
Governments are paying closer attention to charging interoperability. There is regulatory momentum toward standardizing charging connectors in several markets, with the European Union and other regions exploring or implementing rules to reduce e-waste and simplify consumer experiences. While regulatory changes often target connectors (such as USB‑C compatibility) rather than every charging protocol, they influence the market by streamlining compatibility and encouraging universal charging paths.
For consumers, this means you may see more universal chargers and cross-brand compatibility in the years ahead, especially for wired charging. Wireless standards are likely to keep expanding the range of supported devices, but the fundamentals of which protocol a device negotiates with a charger remain important for speed and safety.
What this means for you
When shopping for chargers, check device compatibility with the charger’s standards. If you own newer devices that support USB-C PD or PPS, a high-quality USB-C PD charger is a good bet for fast charging across multiple devices. For wireless charging, ensure your device supports Qi and that the charger’s output matches the desired speed. If you travel or own devices from multiple brands, a single high-wattage USB-C PD charger with the right cables can cover most needs, while wireless pads add convenient desk charging options.
Summary
Chargers do not all transmit power in the same way. The core differences lie in connectors, power profiles, and negotiation protocols. Wired charging is dominated today by USB-C PD (with PPS as a key feature) and a variety of proprietary fast-charging standards that pair with specific devices. Wireless charging centers on Qi, with MagSafe and other brand variants offering additional convenience at varying speeds. Regulatory trends toward universal connectors further shape the market, aiming to simplify use and reduce waste while preserving the need for device-specific compatibility. In short, the transmission method—and the resulting charging performance—depends on both the charger and the device.
Is a scatpack faster than a 392?
No, a 392 is not faster than a Scat Pack because they use the exact same 6.4-liter 392 cubic inch V8 engine with 485 horsepower. The SRT 392 is a trim level that includes additional performance features like larger Brembo brakes, adaptive suspension, and other aesthetic upgrades, while the Scat Pack is the performance trim level that also comes with the 392 engine.

Performance
- Both the SRT 392 and the Scat Pack have identical engine power outputs: 485 horsepower and 475 lb-ft of torque.
- Because the engines are the same, their straight-line performance, like 0-60 mph times, is virtually identical.
Key differences
- SRT 392: Often comes with more premium features as standard, such as larger Brembo brakes, an adaptive suspension system that allows for adjustable ride firmness, and specific SRT badging and interior trim.
- Scat Pack: Is the performance trim that adds the 392 engine to the R/T model. Many of the performance upgrades found on the SRT 392, such as the active suspension and larger brakes, can be optioned on the Scat Pack, making a fully-loaded modern Scat Pack very similar to an SRT 392.

Do all Dodge Chargers have the same transmission?
Except for Charger Pursuit (through 2020), all models came standard with the eight-speed automatic transmission.
Do the RT and Scat pack have the same transmission?
The R/T Scat Pack features everything from the R/T trim and then some. It swaps the 5.7L Eagle HEMI V8 for the 6.4L 392 HEMI V8. This much larger and more powerful engine produces up to 485 hp and 475 lb-ft of torque. The R/T Scat Pack also comes standard with the six-speed manual transmission.
What transmission does my Dodge Charger have?
8 speed automatic transmissions
8 Speed Dodge Charger Transmission
The 8 speed automatic transmissions are made by ZF and have had several versions since their inception in the Dodge Charger models. These transmissions are still being used in the present 2023 Dodge Charger models (at the time of this article being written).
