What Laptop Charger Should You Use: can you replace the original power adapter with a smaller 65W GaN charger?

1. Which charger for a laptop? Why are OEM chargers so big?

a) Silicon-based technology

Traditional laptop power adapters are based on silicon components, which require large transformers and cooling systems.

b) Lack of universality

Most original laptop chargers fit only a specific laptop model and don’t offer extra ports for other devices.

2. What are GaN chargers?

GaN (Gallium Nitride) is a modern semiconductor material that allows more efficient current conduction and lower heat emission. Key advantages:

• More power in a smaller body
• Greater energy efficiency
• Ability to handle multiple devices at the same time

In the DEKO Electronics range you’ll find compact and efficient models such as the DEKO Desktop 65W GaN Fast Charger and the DEKO POWER 100W GaN Fast Charger.

3. Can a GaN charger damage a laptop?

No, provided you choose a certified model compliant with USB-C Power Delivery (PD). The charger and laptop “negotiate” the power level, which prevents overloads.

a) Security systems

Reputable GaN chargers come with certifications (CE, FCC, UL) and protections against short circuit, overheating and overloading. Examples include the DEKO 65W GaN Fast, DEKO 67W GaN Fast (white), and DEKO 100W GaN Fast, all of which feature advanced safety mechanisms.

4. Is 65W enough for my laptop?

• Ultrabooks and office laptops: 45–65W – ideal for a 65W GaN charger.
• Gaming laptops and workstations: require more power (90W+); it’s worth considering a 100–120W GaN model.

To check the power requirement, look at the voltage (V) and current (A) on the original charger (V x A = W).

5. Universal charging for multiple devices

Advantages of GaN chargers:

• Powering a laptop, phone, tablet and smartwatch with a single device
• USB‑C and USB‑A ports for charging multiple devices at the same time
• Smaller size and fewer cables when travelling

6. Why should you choose a GaN charger?

• Space saving: smaller than the original power adapter
• Safety: modern technology and certifications
• Versatility: the ability to power different devices
• Portability: lightweight design makes it easy to carry

FAQ

1. Will a GaN charger charge my MacBook?
Yes, as long as your MacBook supports the USB‑C PD standard.

2. Can I use a GaN charger with a gaming laptop?
Only if the laptop requires 65W or less. Otherwise, choose a 100W+ model.

3. Do GaN chargers overheat?
No, they have better heat management than traditional power adapters.

4. Can I use one GaN charger for both my laptop and my phone?
Yes, many models have multi-port USB‑C and USB‑A outputs and support various charging standards.

5. What are the best GaN chargers?
Recommended models: DEKO 65W GaN Fast, DEKO 67W GaN Fast (white), DEKO 100W GaN Fast.
