❓ 9. FAQ
Do I need 10A or 5A for phone repair? +
Phone repair typically uses less than 3A. Both are sufficient, but 10A gives you headroom for other projects like battery charging or testing larger devices.
What is "uninterruptible" power supply? +
It means the power supply maintains output even if input power fluctuates. This protects sensitive circuits during testing but is rarely needed for general repair work.
Can the Amazon power supply handle 220V? +
Yes, it has a voltage switch for 110V/220V operation. The SPS305 is 220V only.
Which is better for beginners? +
The Amazon power supply at $49.99 is perfect for beginners. Save your money and get the more affordable option with higher current capacity.
Are these safe for sensitive electronics? +
Both have overload protection. The SPS305 has additional stability for sensitive circuits, but the Amazon unit is perfectly safe for phone repair and general electronics work.
