Review: Good enough for titanium anodizing - Great psu. Cant quite get full current out most of the time(seems to top out at 2.5A at higher voltage), but for a cheap psu it is great. I find this works well for titanium anodizing, but it is slow on large pieces due to the high surface area to amperage ratio. It is super simple to use. Feels super light, but what can ya expect from a cheap psu.
Review: Very flexible and useful - This variable power supply is a game-changer for anyone working with electronics. Its flexibility allows precise voltage and current adjustments to suit various applications. Whether you're a hobbyist, technician, or engineer, its usefulness is undeniable. The intuitive controls make adjustments effortless, ensuring accuracy and reliability. Efficiency is at the heart of its design, minimizing energy waste while delivering stable power output. The sturdy build enhances durability, making it a long-term investment. Overload protection adds an extra layer of safety, preventing damage to your components. Compact yet powerful, it's perfect for any workspace. With consistent performance and user-friendly operation, this power supply is an essential tool for any electronics setup.

### ⭐⭐⭐⭐ Good for the price. Frustrating adjustment knobs.
*by C***D on August 25, 2025*

Decent for a basic power supply, but I can't stand the voltage adjustment. The coarse knob gets you somewhere in the right neighborhood, and then the fine dials it in. Both are ridiculously sensitive. I would prefer a digital adjustment knob. As far as performance, it seems to work well. I haven't tested more than a couple of amps so far, but it worked well for my needs. The device looks great, and has a bright screen.
