Yes, a converter of this type can be used in the 10–100 W range, but the exact board in your photo must be rated for that power. The picture alone doesn't establish its maximum wattage.
For a typical ~90% efficient converter:
| Output power | Approx. input current at 12 V | at 24 V |
|---|---|---|
| 10 W | ~0.9 A | ~0.46 A |
| 50 W | ~4.6 A | ~2.3 A |
| 100 W | ~9.3 A | ~4.6 A |
So 100 W at high voltage requires substantially more input current, especially from a 12 V supply.
If you send me the model number/specification printed on the board or its listing, I can tell you whether that particular module is suitable for 10 W, 50 W, or 100 W. ⚠️ Its high-voltage output can be dangerous.
