Question 1

Will this 45W charger work with my older Samsung phone like the Note 10, S10, or S20?**

Accepted Answer

Yes, it will charge those devices safely, but you’ll see slower speeds than 45W. For example, Note 10 and S10 models top out at 15W–25W fast charging. To get the true 45W “Super Fast Charging 2.0” speeds, you’ll need a recent flagship like the Galaxy S23 Ultra, S22 Ultra, S23+, or Galaxy Tab S8/S8+. If you own an older model, the charger still works — just don’t expect a dramatic speed jump.

Question 2

Do I need to buy a separate cable to reach 45W speeds?**

Accepted Answer

Yes. This listing includes only the wall adapter — no USB-C cable is included. To hit the full 45W output, you’ll need a cable that supports 5A (or at least 100W). Many users on Reddit discovered this only after purchasing and felt misled, so we want to be upfront: factor in the cost of a compatible cable if you don’t already own one.

Question 3

The charger gets warm when I use it. Is this normal?**

Accepted Answer

Some warmth is normal during fast charging, especially at higher wattages. However, if the adapter becomes uncomfortably hot to the touch or smells like burning plastic, stop using it immediately. Several TikTok reviewers noted that the block runs warmer than Samsung’s official brick, particularly when the phone is in use while charging. If you’re concerned, try charging in a well-ventilated area and avoid heavy phone usage (gaming, video streaming) during the cycle.

Question 4

Is this compatible with non-Samsung devices like Pixel, OnePlus, or older Android phones?**

Accepted Answer

It will charge most USB-C devices, but it relies on the USB Power Delivery (PD) standard. Samsung’s proprietary “Super Fast Charging 2.0” protocol works best with Galaxy phones. For Google Pixel phones, you’ll get up to 18W–30W depending on the model. For OnePlus or Oppo phones that use their own proprietary fast-charging standards, you’ll be limited to standard 10W–15W charging speeds. It’s a universal USB-C charger, but fast charging is optimized mainly for Samsung.

Question 5

I’ve heard about heat issues and inconsistent speeds — is it worth saving money over the official Samsung 45W charger?**

Accepted Answer

It depends on your priorities. If you own a recent S22/S23 Ultra and already have a quality 5A cable, this charger delivers comparable speeds at a lower price, and the compact size is a plus for travel. However, if you value consistent performance, a cooler operating temperature, and warranty peace of mind, many users who regretted this purchase recommend paying a bit more for the official Samsung 45W brick or an Anker equivalent. Our advice: check the price difference at checkout — if it’s less than $10–15 apart, go with the Samsung original.
