One of the most common questions we get from beginners shopping for a galvo laser engraver is: "How much power do I actually need? Is 10W enough, or do I need more?"
Power is one of the most important specs to understand, but more power isn't always better – it depends on what you actually want to do. Let's break it down so you can choose the right power level for your needs.
What Does Laser Power Actually Mean?
When we talk about laser power in entry-level galvos like the Tyvok P2, we're talking about the optical output power of the laser diode, measured in watts (W).
Higher power means:
- Faster engraving
- Ability to engrave through thicker materials
- Ability to engrave darker deeper marks on harder materials
- More ability to do thin cutting
Lower power means:
- Slower engraving
- Limited to thinner materials and lighter marks
- Lower cost
Power Level Guide for Entry-Level Galvos (2026)
| Power Level | Best For | What You Can Do |
|
|
|
|
| 2W | Absolute beginners on a budget, testing the waters | Thin materials, shallow engraving, small projects |
| 5W | Most hobbyists and beginners starting a side hustle | Most common engraving materials, faster than 2W |
| 10W | Serious side hustlers and people who want more versatility | Deep engraving, harder materials, faster throughput |
Is 10W Really Necessary? What Can You Actually Do With 10W That You Can't Do With Lower Power?
Let's look at the real-world difference 10W makes:
What You Can Do with 10W:
✓ Deep, dark engraving on hardwood – One pass is often enough where 2W or 5W would need multiple passes
✓ Engraving on stainless steel – Get clear, dark marks that hold up over time
✓ Faster production – Cut your engraving time roughly in half compared to 5W
✓ Cutting thin materials – Can cut thin wood (up to ~3mm) and thin acrylic
✓ Works through heat transfer materials – Good for making custom tumblers and other coated items
What Can Lower Power Do?
2W-5W can absolutely still do most basic engraving projects:
- ✓ Soft wood
- ✓ Acrylic
- ✓ Leather
- ✓ Anodized aluminum
- ✓ Most small custom projects
But you'll need slower speeds and sometimes multiple passes to get the same depth and contrast that 10W gets in one pass.
Do You Really Need 10W? Let's Answer the Question by What You Want to Do
You Definitely Should Get 10W If:
- 👉 You're planning to run a business and do multiple orders per day
- 👉 You want to engrave on stainless steel and other hard metals
- 👉 You want the fastest possible throughput so you can do more orders
- 👉 You want to be able to cut thin materials occasionally
- 👉 You want deeper, darker engraving in fewer passes
- 👉 You have the extra $30-$50 in your startup budget
In 2026, the price difference between 5W and 10W on the Tyvok P2 is minimal – you can get the 10W for under $200 total. For most people, it's worth the small extra investment.
2W or 5W is Probably Enough If:
- 👉 You're just testing the waters and not sure if you'll even use it much
- 👉 You're on an extremely tight budget and every dollar counts
- 👉 You only plan to do it as a hobby, not for making money
- 👉 You only engrave soft materials like wood and leather
Real World Speed Comparison: 2W vs 5W vs 10W
Let's look at how long it takes to engrave a standard 2" × 1" dog tag:
| Power | Speed (one pass) | Result |
|
|
|
|
| 2W | ~60 seconds | Light engraving, may need second pass |
| 5W | ~30 seconds | Good contrast, one pass enough for most uses |
| 10W | ~15 seconds | Deep dark contrast, one pass done |
That's a huge difference when you're doing multiple orders per day. 10W lets you do 4x as many tags per hour as 2W. That translates directly to more money in your pocket when you're running a business.
Common Myths About Laser Power Debunked
Myth 1: "More power means better quality"
Reality: Power matters, but precision and focus matter more. A well-focused 10W galvo from a reputable brand like Tyvok will outperform a poorly-made 20W from an unknown brand.
Myth 2: "You need 50W+ to do anything useful"
Reality: That's for industrial CO2 lasers. For entry-level diode galvos, 10W is more than enough for 90% of what beginners want to do.
Myth 3: "Higher power will wear out faster"
Reality: If you use it correctly, quality diodes last thousands of hours. Even with daily use, a 10W diode should last you 3-5 years or more.
Our Recommendation for Most Beginners in 2026
For 80% of beginners buying their first galvo laser engraver, we recommend getting the 10W version.
Here's why:
1. The price difference is small in 2026 (usually just $30-$50 more than 5W)
2. 10W gives you more versatility for future growth
3. Faster engraving means you can do more orders and make more money
4. You can still do everything the lower power models can do, just faster
5. If you decide to grow your business, you won't outgrow your power as quickly
The only time we recommend starting lower than 10W is when you're really on an extremely tight budget or you just want to try it as a hobby with no plans to make money.
What About the Tyvok P2 10W?
The Tyvok P2 is a perfect example of an entry-level 10W galvo that gives you great value. You get a full 10W optical power for under $200, which is unheard of even just a couple years ago.
