Review: ★★★★★ 5/5 stars Great power supply—stable, easy to use, and very reliable. Highly recommended! - This power supply works perfectly—stable output, easy to adjust, and very reliable. The display is clear, and the safety features give me peace of mind. Excellent quality for the price!
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.

### ⭐⭐⭐⭐⭐ Good enough for titanium anodizing
*by A***. on January 17, 2026*

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.

Feels super light, but what can ya expect from a cheap psu.

### ⭐⭐⭐⭐ 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.
