Which charger for Samsung Galaxy A37 5G? The right plug for 45W speeds

You just unboxed your new phone, but you only found a USB-C cable in the package. To get the fastest possible charging speeds, you need a power adapter that supports USB Power Delivery PPS and delivers at least 45W. Which charger for Samsung Galaxy A37 5G will give you top speeds without wasting your money?

This phone accepts up to 45W, but only when paired with a compatible adapter that meets Samsung's technical power profile. If your charger lacks PPS support, the device will simply charge at a lower, non-PPS speed.

In this guide, you will learn how to check the power bricks you already own, how fast the phone actually charges, and which models deliver genuine 45W speeds.

Fun fact: The Galaxy A37 5G is the very first smartphone in Samsung's popular Galaxy A3x series to support 45W fast charging, an upgrade previously limited to flagship devices.

Specs and charging

The key Samsung Galaxy A37 5G specs that matter when choosing a charger:

• Battery: 5000 mAh, litowo-jonowa
• Wired charging: 45 W (Super Fast Charging 2.0 (USB PD PPS))

Can you use a power adapter you already have in a drawer?

Before buying a new plug, check the fine print printed on the side of your existing power adapters. Look specifically for the "Output" section to see if it lists PPS alongside USB PD.

• Old Samsung 25W charger (EP-T2510): If you have this adapter from an older Galaxy phone, it will output around 24.8W. That delivers roughly 55% of the phone's maximum speed, which is still plenty fast for standard everyday use.
• USB-C laptop power bricks: A 45W or 65W laptop charger will power the phone safely. However, if the brick lacks the PPS profile reaching up to 16V / 3A, the phone will negotiate standard USB PD and charge noticeably slower.
• Standard 20W phone chargers: Typical 20W adapters without PPS will supply power, but they remain capped well below what this phone can accept.
• Proprietary chargers from other phone brands: Adapters that rely on custom fast-charging protocols will not activate fast charging on this device and will drop to basic speeds.

Real charging performance: what do the numbers mean in daily life?

In independent charging tests by GSMArena, the phone reached 34% battery in just 15 minutes. That means a quick top-up while drinking your morning coffee gives you enough battery to handle your commute and early work hours.

If you have half an hour, the phone climbs to 62% in 30 minutes. That is plenty of charge to easily last you through the rest of the day and evening.

A full cycle from empty to 100% takes about 72 minutes when using an optimal 45W PPS adapter. Charging naturally slows down as the battery fills up to keep temperatures stable.

Fun fact: You do not need a specialized 5A cable to get the full 45W speed on this phone; the standard 3A USB-C cable included in the box is fully rated for the job.

Selecting the best adapter for your specific needs

If you want the official manufacturer accessory, the Samsung 45W Power Adapter EP-T4511 gives you the full ~45W output and reaches 100% of the phone's charging potential. It is designed precisely for Samsung's charging standards.

For the lowest price while still getting maximum speed, the Google 45W USB-C Charger also hits the full ~45W ceiling. It offers clean PPS compatibility at an accessible price point.

If you want a single brick that handles both your phone and your laptop, the UGREEN Nexode 65W or the Anker 735 (Nano II 65W) are great choices. Both output up to ~45W for this phone while offering three ports to recharge multiple gadgets at once.

If you prefer a smaller plug and do not mind slightly slower replenishment, the Samsung 25W Power Adapter EP-T2510 delivers around 24.8W (55% of the real maximum) in a very compact format.

Technical details and charging mistakes to avoid

The biggest pitfall is buying a standard 45W or 65W USB-C charger that lacks PPS. Without PPS, the Galaxy A37 5G cannot request its ideal voltage, leading to a much slower charging session.

Pay close attention to the PPS voltage and current limits on third-party chargers. The phone utilizes a PPS window up to 16V / 3A; adapters with lower PPS current limits will deliver less power.

Finally, avoid relying on proprietary fast-charging bricks from other manufacturers. Because they rely on closed standards instead of open USB PD PPS, this phone will not draw full power from them.

Helpful answers about powering your Samsung Galaxy A37 5G

Which charger for Samsung Galaxy A37 5G gives full 45W speed?

To reach the full 45W rate, you need an adapter that supports USB PD PPS with a profile reaching up to 16V / 3A. Options like the Samsung 45W Power Adapter EP-T4511 or Google 45W USB-C Charger provide the exact protocol required.

Does the Galaxy A37 5G come with a charger in the box?

No, Samsung only includes a USB-C to USB-C cable inside the box. You will need to use a compatible charger you already own or buy a new USB PD PPS adapter separately.

Do I need an expensive 5A cable to charge at 45W?

No, a 5A cable is not necessary for this specific phone. Because the device charges at up to 16V at 3A, the standard 3A USB-C cable included in the box is sufficient to hit maximum speed.

Can I safely charge this phone with a 65W laptop adapter?

Yes, you can safely connect a 65W or higher USB-C charger. The phone automatically controls how much power it draws, though you will only hit full 45W speeds if that laptop brick supports the necessary PPS profile.

How long does a complete charge take from zero to 100%?

According to test results, a full charge takes approximately 72 minutes using a 45W PPS charger. You can also expect around 34% after 15 minutes and 62% after 30 minutes on the plug.
