5 Best Galaxy A37 Chargers in the United States (2026 Buying Guide & FAQs)
The Samsung Galaxy A37 5G packs a 5,000mAh battery and supports 45W Super Fast Charging 2.0 over USB-C with Power Delivery (PD) and Programmable Power Supply (PPS) — but like most Galaxy A-series phones, Samsung doesn’t include a wall adapter in the box, only a USB-C to USB-C cable. That means picking the right charger is the difference between a 5-hour trickle charge and a 60%-in-30-minutes top-up.
Here’s a look at five solid charger options for the Galaxy A37, plus a buying guide and answers to common questions.
Quick Answer: What Charger Does the Galaxy A37 Need?
To hit full Super Fast Charging 2.0 speeds, look for:
- USB-C output of at least 45W
- PPS (Programmable Power Supply) support — this is what actually unlocks Samsung’s Super Fast Charging behavior, not just raw wattage
- A USB-C to USB-C cable rated for at least 3A / 60W, since the phone charges via higher voltage and lower amperage
Any well-made 45W–65W GaN charger with PPS will work fine, and a higher-wattage multi-port charger (like a 65W unit) won’t overcharge or damage the phone — it will simply deliver the 45W the A37 is designed to draw.

Buying Guide: How to Choose a Galaxy A37 Charger
1. Match the wattage — or go higher, never lower. The A37 caps out at 45W, but a 65W or even 100W charger will work fine since the phone only draws what it needs. A charger under 45W (like a basic 15W or 25W brick) will still charge the phone, just far more slowly.
2. Look for PPS, not just “PD.” Standard USB-PD alone isn’t enough to unlock Samsung’s full Super Fast Charging speed. Confirm the charger explicitly lists PPS (Programmable Power Supply) support — most Samsung-marketed or Samsung-compatible chargers do.
3. Don’t skimp on the cable. A weak or uncertified USB-C cable is one of the most common reasons phones “fast charge” slower than expected. Look for a cable rated 3A/60W or higher, ideally with an E-marker chip for higher-wattage charging.
4. Consider port count and travel needs. If you regularly charge multiple devices, a 2-3 port GaN charger (65W+) is more practical than a single-port brick, since GaN chargers run cooler and smaller than older silicon designs at the same wattage.
5. Check for safety certifications. Look for UL, FCC, or CE certification, along with built-in protections against over-current, over-voltage, and overheating — especially important with third-party bricks.
FAQs
Does the Galaxy A37 come with a charger in the box? No. Like most recent Galaxy A-series phones, the A37 ships with only a USB-C to USB-C cable — the wall adapter is sold separately.
What’s the fastest way to charge the Galaxy A37? Using a 45W (or higher) PPS-compatible USB-C charger with a quality 3A+ cable, Samsung states the phone can reach about 60% charge in 30 minutes via Super Fast Charging 2.0.
Can I use my old Samsung charger from an S21 or S22? Yes, as long as it supports at least 25W with PPS you’ll get meaningfully faster charging than a basic 5W-15W brick, though you won’t hit the full 45W ceiling unless the charger is rated for 45W or higher.
Will a 65W or 100W charger overcharge or damage the A37? No. The phone’s internal charging controller negotiates the power it actually draws (up to 45W), so higher-wattage multi-port chargers are safe to use.
Do I need a special cable, or will any USB-C cable work? Any USB-C to USB-C cable will charge the phone, but only cables rated for at least 3A/60W (with PPS support) will unlock full Super Fast Charging speeds. Thin or bundled low-cost cables often bottleneck charging speed.
Is wireless charging an option for the Galaxy A37? The Galaxy A-series, including the A37, does not support wireless charging — it charges exclusively via the USB-C port.
