What Are the Different Types of Phone Chargers?
Don't guess which phone charger to get anymore. Concepts like USB-C, GaN, and 30W can be very confusing. This guide is really direct. We talk about the different sorts of phone chargers based on their plug type, shape (such wall bricks or power banks), charging technology, and power speed (watts).
By the Plug: Phone Charger Connector Types
The clearest difference between chargers is the plug. It's helpful to think of a charging cable as having two ends:
The Power Port (on the Charger)
This is the port on the wall charger, power bank, or computer.
USB-A: The traditional, large rectangular port. This is the standard on older or basic chargers and generally supports slower charging.
USB-C: The modern, small oval port. This is the new standard for fast chargers (including GaN) because it is required for high-speed technologies like USB Power Delivery (USB-PD).
The Device Connector (into your Phone)
This is the end that plugs into your phone, tablet, or headphones.
This guide, and the chart below, focuses on the device connector—the part that plugs into your phone. There are three main types you need to know:
USB-C: The new universal standard. A small, reversible oval plug.
Lightning: Apple's proprietary plug. A small, reversible plug used on iPhones 14 and older.
Micro-USB: The older standard. A small, D-shaped plug that only fits one way.
This chart shows which connectors plug into your devices:
Chart 1: Device Connector Types (The Plug)
Connector Type | Appearance | Common On... |
USB-C | Small, symmetrical oval | New Phones: iPhones (15+), all modern Androids. Laptops & Tablets: MacBooks, iPads, Dell, HP. |
Lightning | Small, symmetrical, thin plug | Older Phones: iPhones (14 and earlier). Other Apple: AirPods, older iPads. |
Micro-USB | Small, D-shaped (not reversible) | Older Phones: Androids (before 2018). Other Devices: Bluetooth speakers, cameras, power banks. |
An Important Note on Cables:
The cable you use connects these two ports.
USB-C to USB-C Cable: This is the modern standard for fast charging. It connects a new USB-C charger to a new USB-C device (like an Android phone, iPhone 15, or laptop).
USB-C to Lightning Cable: This is used to fast-charge an iPhone 14 or older with a new USB-C charger.
USB-A to C/Lightning/Micro-USB Cable: This is used to connect any device to an older USB-A charger.
And here is a more detailed look at what devices use each plug:
Chart 2: What Devices Use Which Connector?
| Connector | Phones That Use It | Other Devices That Use It |
| USB-C | • iPhones (15 and newer) • Samsung Galaxy (S9, Note 9, and newer) • Google Pixel (all models) | • Laptops (MacBooks, Dell, HP) • Tablets (iPad Pro/Air, Galaxy Tab) • Nintendo Switch / Steam Deck • New headphones, drones, cameras |
| Lightning | • iPhones (14, 13, 12, 11, X, 8, and older) | • AirPods (most models) • Older iPads (Base and Mini models) • Apple accessories (keyboards, mice) |
| Micro-USB | • Older Androids (before ~2018) • Many entry-level phones | • Older power banks • Bluetooth speakers • E-readers (older Kindles) • Digital cameras |
By the Form: Types of Phone Chargers by Design
"Charger" refers to various designs, not limited to the wall brick. It describes how and where you get power.
Wall Chargers: The most common type. They plug directly into an outlet. Modern GaN versions are tiny, fast, and can have multiple ports (often USB-C).
Multi-Port Desktop Chargers: A single hub for your desk, often with a longer cord. It charges all your devices (phones, tablets, watches) from one outlet.
Wireless Chargers: Offer "drop and charge" convenience. You place your phone on a pad or stand, and it charges cable-free using the Qi standard (or MagSafe for Apple).
Car Chargers: Plug into your car's 12V outlet to fast-charge your phone while you drive. Look for one with a high-wattage USB-C port.
Portable Chargers (Power Banks): Power banks that let you charge anywhere. They range from small "lipstick" tubes for one top-up to large banks that can charge laptops.
By the Smarts: Key Charging Technologies
The "smarts" inside your charger control the speed and safety of your charge. These technologies let your phone go from 0% to 50% in 30 minutes.
USB Power Delivery (USB-PD)
You should know about USB-PD. USB-PD is the universal fast-charging standard that works over a USB-C cable.
It works like a smart talk between your devices. Your phone (like an iPhone or Google Pixel) "talks" to the USB-PD charger and says, "Hi, I can safely take 30W of power." The charger then replies, "Great, sending 30W!" This process, which requires a USB-C port, ensures you always get the fastest and safest charge.
Qualcomm Quick Charge (QC)
This is another very popular fast-charging technology. Qualcomm developed it for many Android phones (like those from Samsung, LG, and Motorola). Many modern chargers work with both USB-PD and QC, making them very versatile.
GaN (Gallium Nitride) Technology
GaN is the "secret sauce" behind the new wave of tiny, powerful chargers. For decades, companies made chargers with silicon. GaN is a new material. It works more efficiently and produces less heat. This allows makers to pack components much closer together.
What this means for you: A 100W GaN charger can be the same size as an old 30W silicon charger. This lets you have one small brick (with USB-C ports) that fast-charges your phone, tablet, and laptop all at once.
By the Speed: How to Tell Different Chargers Apart
We measure all these phone charger types by their power output in watts (W). More watts generally means a faster charge, but only if your phone can handle it.
You can tell chargers apart by:
Looking at the Cable's Plug: As we saw in Chart 1, this tells you what devices it fits.
Looking at the Power (Watts): Look at the fine print on the charging brick. It will say "Output" and list a number in Watts (W), like 5W, 20W, or 65W.
Looking at the Form: Is it a wall brick, car charger, power bank, or wireless pad?
This chart breaks down charger speeds by watts:
Chart 3: Charger Types by Power (The Speed)
Power (Watts) | Charging Speed | Best For... |
5W - 12W | Slow (Standard) | Old USB-A chargers, basic phone top-ups, small devices like wireless earbuds. |
15W - 45W | Fast Charging | Most smartphones (via USB-C). Can charge a phone from 0-50% in about 30 minutes. |
65W - 140W+ | Ultra-Fast | Laptops. Will also safely fast-charge your phone and tablet at their top speed (via USB-C). |
Powering Your Life: At Home and On the Go

How to Choose the Right Phone Charger
Feeling more confident? Use this simple 4-step checklist:
Check Your Phone's Port: Does it use USB-C or Lightning? (See Chart 1). This tells you the device end of the cable you need.
Check Your Phone's Speed: Search for your phone model's "maximum charging speed" (e.g., "iPhone 15 charging speed"). This tells you if you need a 20W, 30W, or 45W charger for the fastest speeds.
Choose Your Form: Where will you charge most? Get a GaN wall charger (with USB-C ports) for home, a USB-PD car charger for the car, and a power bank for when you're on the go.
Look for the Tech: For maximum speed and compatibility, choose a charger with USB-C ports that features USB-PD and GaN technology. Then, get the right cable (like a USB-C to USB-C cable) to match.
Conclusion
It's not hard at all. You just want to know that when you plug in your phone, it will charge as quickly and safely as possible.
You know what to do now to make that happen. You know to look for the right energy (W) for your device and USB-PD (which requires a USB-C port) for smart charging. GaN is for a smaller, more powerful brick.
All of EcoFlow's chargers are based on that same technology. We think you shouldn't have to pick between size, speed, and safety. You can have all three. EcoFlow has the right tool for you to stay charged whether you're at your job or on the go.
Frequently Asked Questions (FAQs)
Q1. What's the difference between the USB-A and USB-C ports on a charger?
Think of USB-A as the old, familiar port—that big, rectangular plug. It's on older chargers and provides basic charging, but it's limited on speed and doesn't support the new USB-PD fast-charging standard.
USB-C is the new standard port on the charger itself. It's that small, oval-shaped plug. The big difference is that it's "smart." It uses technology like USB Power Delivery (USB-PD) to "talk" to your device and charge it way faster. You need a USB-C port on your charger and a USB-C cable (like C-to-C or C-to-Lightning) to get the fastest speeds for new phones, tablets, and laptops.
Q2. Is wireless charging slower than using a cable?
Yes, almost always. A typical wireless charger gives you about 5W to 15W of power. A good fast charger with a USB-C cable (and USB-PD) can easily give you 25W, 45W, or even more.
Wireless charging is awesome for convenience—like dropping your phone on a pad overnight. But if you're in a hurry and need power now, you should always use a cable.
Q3. Can I use my old 5W or 10W charger for my new phone?
Yes, you totally can. If it's an old USB-A charger, you just need the right cable (like a USB-A to USB-C cable). It won't hurt your new phone's battery at all.
But, it will be painfully slow. Your new phone is probably designed to charge at 30W. If you only give it 5W, it's like trying to fill a bathtub with a leaky faucet. A charge that should take an hour might suddenly take 3 or 4 hours.
Q4. Do all USB-C chargers and cables perform the same?
No! This is a super important one.
"USB-C" just describes the shape of the plug. The actual speed depends on the technology inside.
You can buy a cheap USB-C charger that only puts out 15W (which is pretty slow). On the other hand, a high-quality GaN or USB-PD charger can put out 100W or more from its USB-C port. To get those top speeds, you have to look for two things: the power output (in Watts or "W") and support for "USB-PD."
Q5. What's more important: the charger brick or the cable?
They're a team, but the charger brick (the part that plugs into the wall) is the 'brain' of the operation. It decides the maximum power you can get.
You must have a powerful brick (like a 30W USB-PD one) to get fast charging.
However... you also need a cable that can handle that power. If you pair your powerful new USB-C brick with an old, low-quality cable (or the wrong type, like a USB-A cable), it will just slow everything down. To get the best speeds, you need a high-quality brick and a high-quality cable that is rated for fast charging (like a "100W USB-C cable").
