Review: The only power supply you’ll ever need - I never thought I’d need a power supply like this. I’ve been making do with the universal power supplies and thought that was good enough. Well, that may have been so. But a synthesizer I was working on had so much noise that I couldn’t pinpoint. It turned out that my universal power supply was noisy. A second one didn’t even work at all. I connected it up to this regulated power supply and everything worked perfect! The price was right for the convenience. It has earned a permanent place on my workbench
Review: I've Got The Power! - Oh, Snap! If you want unlimited power, go get yourself some Infinity Stones. If you want unlimited CONTROL of a limited amount of power, but this power supply. These things are great for nerding out with geeky electronics, testing electronics, and even rejuvenating rechargeable AA and AAA batteries that won't take a charge on that crappy charger that Energizer and Duracell sell you. Yeah, you didn't know you could do that did you? You thought those really expensive AAs that you swear you only charged twice were totally ruined, despite the manufacturer's claim that you could charge them 1,000 times. Nope. Not ruined. The charger just thinks they are. Zap them real quick with 1.6v from this charger (literally a couple seconds), pop them back in the charger, and watch them charge!

## Features

- HIGHER PRECISION WITH DATA HOLD FUNCTION - ENGINDOT DC Power Supply uses digital control technology, you can switch between coarse and fine adjustment by simply pressing the encoder knob, customize each digit in the range of 0-9. Press both knobs simultaneously for 3 seconds to hold a set of values, then press for 3 seconds to release.
- 4 DIGITS CLEAR AND ACCURATE READOUTS - 0.01V and 0.01A resolution, you can easily adjust from 0-30V and 0-5A; 4-digit backlit LED display works even in low voltage conditions Provides more accurate and clearly visible readings of voltage and current values.
- CONSTANT VOLTAGE (CV) AND CURRENT (CC) MODE - Adjust the coarse and fine adjustment knobs to easily dial in the required voltage and current; when the load current reaches the current limit value, it will automatically switch to the constant current mode, which can be easily seen to current and voltage as circuit elements switch.
- MULTIPLE PROTECTIONS, SAFTY FIRST - ENGiNDOT bench power supply featured with grounding wire, thermal protection, voltage overload and short-circuit protection ensure the safety; The built-in fan reduce the operation noise, prolonging the life of product effectively. With an output button, this button can prevent you from damaging the device by forgetting to disconnect the output
- VERSATILE USAGE - Compact and lightweight, doesn't take up of space, ideal for a variety of applications such as school lab experiments, cell phone repair, electronics production assurance specifications, and lab measurements.

### ⭐⭐⭐⭐ Great for the price, but as few flaws
*by A***R on August 29, 2022*

So for the price it is a pretty nice little bench power supply. Around 300 Watts of output, but does make some electronic whining sounds when using it sometimes. Not sure how long it will last, but is working for what I need. It has constant current and constant voltage which is ideal.
