Buying a Portable Charger for Nintendo Switch? Don’t Make This Mistake!

Grabbing just any portable charger without checking compatibility can be a costly mistake. Unlike smartphones, the Nintendo Switch has specific power requirements. Using the wrong charger can lead to:

• Slow charging (or no charging at all)
• Inefficient power transfer, draining your power bank faster
• Battery damage over time

To avoid this, here’s what you need to look for when choosing a portable charger for Nintendo Switch.

What to Look For in a Nintendo Switch Power Bank

Now that you know what NOT to do, let’s break down the key features that will keep your Switch powered up without issues.

1. Battery Capacity: How Much Do You Need?

The Nintendo Switch has a built-in 4,310mAh battery, which lasts about 3–6 hours, depending on the game. Here’s how different power banks compare:

Pro Tip: If you travel often, make sure your Nintendo Switch power bank meets airline regulations (max 27,000mAh or 100Wh).

2. Power Delivery (PD): A Must-Have Feature

Power Delivery (PD) is essential for fast charging your Switch. Without it, your device may charge too slowly or even continue draining battery while plugged in. 

• The Switch supports up to 18W PD charging, so look for a power bank that delivers at least 18W via USB-C PD. 
• Avoid power banks that only support Quick Charge (QC), as the Switch is not compatible with that protocol.

3. Output Wattage: How Fast Should It Be?

The Switch charges best with 18W USB-C PD. Higher wattage (like 30W+) won’t speed up charging but can be useful if you also charge laptops or other high-power devices.

Best choice: A portable charger for Nintendo Switch with at least 18W USB-C PD output to keep it charged while playing.

4. Cable Matters: Use the Right One

Not all charging cables are created equal. The safest option is a USB-C to USB-C cable with a 56kΩ resistor, ensuring proper power delivery without risking damage to your Switch. If you’re using an older power bank with a USB-A port, a USB-A to USB-C cable can work, but charging will be significantly slower.

Pro Tip: For comfort during gameplay, a longer 2-meter cable is recommended so you can play while charging without being tethered too closely to the Nintendo Switch power bank.

5. Safety and Reliability: Not All Power Banks Are Switch-Safe

Since the Nintendo Switch does not follow standard USB-C charging protocols, some power banks can cause issues like overheating or battery failure.

Look for these signs of a safe and reliable power bank:

• Power Delivery (PD) support (minimum 18W output)
• Well-known brand with positive reviews (avoid no-name brands with questionable claims)
• Certified cables with proper resistance (56kΩ resistor)
• Airline-approved battery capacity (if you travel frequently)

Avoid cheap, unbranded chargers, as they may not regulate power properly.

6. Travel Considerations: What’s the Best Size?

If you’re taking your Switch on flights, remember that airlines have restrictions on battery sizes. 

• Most airlines allow up to 27,000mAh (or 100Wh) in carry-on luggage.
• A 20,000mAh power bank is a great middle ground—it’s travel-friendly, provides ample battery life, and is not too bulky.

7. Pass-Through Charging: Is It Worth It?

Some power banks allow pass-through charging, meaning they can charge your Switch while being charged themselves. This is useful when you're near an outlet but still want to continue playing. If this feature matters to you, check whether the power bank explicitly supports it.

8. Build Quality & Durability

• A well-built power bank with heat management prevents overheating.
• Rubberized or textured designs improve grip, reducing the chance of drops.
• Some power banks have built-in stands, making tabletop gaming easier.

9. Multiple Ports for Charging Other Devices

If you travel with a phone or other gadgets, a power bank with multiple ports is useful. Some models even include dual USB-C ports, allowing you to charge your Switch and another device at the same time.

10. Sleep Mode & Auto-Shutdown Features

Some power banks automatically turn off when the Switch is fully charged to prevent overcharging. This feature helps extend battery lifespan and ensures your power bank isn't drained unnecessarily.

Tips for Using a Portable Charger for Nintendo Switch

• Can You Use the Switch While Charging? Yes, but for faster charging, use a high-wattage Nintendo Switch power bank and keep graphics settings lower.
• Avoid Deep Discharges: Try not to let your Switch battery reach 0%, as deep discharges can shorten its lifespan.
• Use Short, High-Quality Cables: A well-made USB-C cable ensures efficient power transfer and prevents overheating.
• Monitor Temperatures: Avoid gaming in extremely hot conditions to prevent overheating.
• Disable Performance-Intensive Features: Lowering brightness and enabling Airplane Mode can extend battery life while charging.

How to Find the Best Nintendo Switch Power Bank

1. Read Reviews: Look at feedback from other buyers to gauge how well a power bank performs in terms of charging speed and reliability.
2. Join Forums & Communities: One of the best ways to find a reliable portable charger for your Nintendo Switch is by checking out gaming communities like r/Switch. Real-world experiences from other players can help you avoid bad purchases and find the best options for your needs.
3. Watch Video Reviews: Video reviews often showcase actual charge speeds and efficiency, giving you a better idea of how a power bank performs in real use.
4. Look for User Comparisons: Side-by-side comparisons between different power banks can highlight the best choices for your gaming setup.
5. Check Manufacturer Specs: Always check if the charger meets the Nintendo Switch’s power requirements before making a purchase.

Portable Charger for Nintendo Switch: Your Must-Have Checklist

Picking the right portable charger for Nintendo Switch isn’t just about battery size—it’s about finding one that delivers safe, efficient charging. To avoid frustration, remember these key points:

• Right Capacity – 10,000mAh for short trips, 20,000mAh+ for extended gaming.
