Android chargers go by several names depending on the connector type and power standard

The term "Android charger" is informal shorthand, but the actual names depend on what connector your phone uses. Most modern Android phones use USB-C, which is the flat, oval connector you'll see on newer Samsung, Google Pixel, OnePlus, and many other brands. Older Android phones used Micro-USB, the smaller rectangular connector that was standard for years. Some phones still use proprietary connectors — Samsung Galaxy Tab S tablets use USB-C, but older Samsung devices used 30-pin connectors unique to that brand.

When you buy a charger, you're actually buying two things: the cable (named for its connector type) and the power adapter (the brick that plugs into the wall). A complete charger setup is often called a "charging kit" or just referred to by its connector — "a USB-C charger" or "a Micro-USB charger." The power standard matters too: chargers labeled 5W, 18W, 30W, or higher refer to how much power they deliver, which affects how fast your phone charges.

Key Takeaways

  • USB-C is the standard connector on most modern Android phones, while older phones used Micro-USB or proprietary connectors.
  • A charger consists of a cable (named for its connector) and a power adapter (the wall brick), often sold together as a kit.
  • The wattage number (5W, 18W, 30W) tells you the power delivery speed, not the connector type.
  • Not all chargers work with all phones — the connector type must match your phone's charging port.

USB-C: The current standard for most Android phones

USB-C became the dominant connector for Android phones around 2015 and is now standard across most brands. It's a small, flat, oval-shaped connector that's reversible — you can plug it in either way without looking. Google Pixel phones, Samsung Galaxy S21 and newer, OnePlus, Motorola, and most other major Android manufacturers now ship with USB-C.

USB-C cables are also used for laptops, tablets, and many other devices, which means you can often use the same cable across multiple devices. A USB-C charger typically comes as a cable with a USB-C connector on one end and a power adapter on the other. When shopping, you'll see them labeled simply as "USB-C charger" or "USB-C charging cable."

Micro-USB: The older Android standard

Before USB-C, Micro-USB was the standard connector on Android phones from roughly 2008 to 2015. It's a smaller, rectangular connector that only fits one way. If you own an older Android phone — anything from that era made by Samsung, HTC, LG, or other brands — it likely uses Micro-USB.

Micro-USB chargers are still widely available because millions of older phones are still in use. They're cheaper than USB-C chargers and often sold in multipacks. You'll find them labeled as "Micro-USB charger" or "Micro-USB charging cable." The connector is noticeably smaller and more fragile than USB-C, and the port on older phones often wears out with repeated use.

Proprietary connectors on specific brands

Some Android devices use connectors made only for that brand. Samsung's older Galaxy Tab tablets used a 30-pin connector unique to Samsung devices. Some older Samsung phones had their own proprietary connectors too. These chargers are harder to find because they only work with that specific device or product line.

If you have an older tablet or phone and can't find a charger that fits, check the device manual or the manufacturer's website to identify the exact connector type. You may need to order directly from the manufacturer or a specialty retailer, as these chargers are no longer stocked in most stores.

Power adapters and wattage ratings

The power adapter — the part that plugs into the wall — is rated by wattage: 5W, 10W, 18W, 30W, 65W, or higher. This number tells you how much power the charger delivers to your phone. A 5W charger is slow; an 18W charger is moderate; a 30W or higher charger is fast. Your phone's manual or the manufacturer's website lists what wattage it supports.

Using a higher-wattage charger than your phone supports won't damage it — modern phones have built-in protection that limits how much power they accept. However, using a lower-wattage charger will charge your phone more slowly. The connector type (USB-C, Micro-USB) and the wattage are separate specifications, so you need to match both to your phone.

How to identify what charger your phone needs

The easiest way is to look at your phone's charging port. If it's a small, flat, oval shape, it's USB-C. If it's a small, rectangular shape, it's Micro-USB. If it's something else entirely, check your phone's manual or search the model number plus "charging port" online.

You can also check the original charger that came with your phone — the connector type is printed on the cable or adapter. If you've lost the original, the phone's settings menu sometimes lists the recommended charger wattage, or you can find it on the manufacturer's support page by entering your phone model.

Where charger names appear when shopping

When you search for a charger online or in a store, the name appears in the product title and description. You'll see labels like "USB-C Fast Charger 30W," "Micro-USB Charging Cable," or "Samsung USB-C Charger." The connector type always comes first, followed by the wattage if it's a fast charger. Some listings also specify "wall charger" (the adapter and cable together) versus "car charger" (designed for vehicle power outlets) or "portable charger" (a battery pack).

Reading the product description carefully matters because a charger labeled "USB-C" won't work with a Micro-USB phone, and vice versa. Many retailers sell multipacks with multiple connector types, which is useful if you own devices with different ports.

Frequently Asked Questions

Can I use any USB-C charger with my Android phone?

Most USB-C Android phones will charge with any USB-C charger, but the wattage matters for speed. A 5W charger will work but charge slowly; a 30W charger will charge faster if your phone supports it. Check your phone's manual to see the recommended wattage.

Are all Android chargers the same?

No. Android phones use different connector types — USB-C, Micro-USB, or proprietary connectors — so a charger for one type won't fit another. Even phones with the same connector type may charge at different speeds depending on wattage.

What's the difference between a charger and a charging cable?

A charging cable is just the cord with connectors on both ends. A charger includes the cable plus the power adapter (the brick). When people say "I need a charger," they usually mean the complete kit, though you can buy cables and adapters separately.

Do I need to buy the official charger from the phone manufacturer?

No. Third-party chargers with the correct connector type and wattage work fine and are often cheaper. Look for chargers from reputable brands and check reviews to avoid low-quality products that charge slowly or fail quickly.

Why does my phone charge slowly with some chargers?

The charger's wattage is usually the reason. A 5W charger charges much slower than an 18W charger. Also, using a charger while the phone is in heavy use (playing games, streaming video) slows charging because the phone uses power while charging.
