Review: Works flawlessly, auto-on with input power a big plus! - Used to power a 7" plasma ball for a wizard staff project. Provides plenty of power. The adjustability is great, but the mode select is... not.
Review: Easy to adjust - I purchased this to replace the missing power supply on My weather-band radio. I needed 11.4 volts. The new power supply was a lot of money. This works perfect. This Buck converter can be used to charge lithium batteries. Input voltage can be adjusted up or down. Input 4 to 13vDC and the output .5 to 30VDC. Easley done pressing buttons and watching LCD. I can use it to power it on other items. Easy enough. It is also can be used as a battery charger for Lipo batteries. Did this also when my RC battery charger failed. This is a lot of Bang for the BUCK. ( no pun intended.

## Features

- ★The Output Voltage Can Be Adjusted Arbitrarily: The Adjustable USB Step Up Down Power Supply Module used as a USB input adjustable desktop power supply, the output voltage can be adjusted arbitrarily, and the current limit is 0-2A (wide input 4-13V, wide output 0.5-30V arbitrarily adjusted, with short circuit protection, the short circuit does not burn)
- ★Safe to Use: Used as a USB charging cable, the charging voltage and maximum charging current can be adjusted arbitrarily (any voltage, with constant current, anti-backflow, which can meet the charging of most batteries)
- ★Three Input Power Modes: Input 1: Standard Type A USB Male. It just can input DC 5V. Input 2: Micro USB Female. It just can input DC 5V. Input 3: IN+ and IN- welding pads. It can input DC 4.0V-13.0V. When using the welding pad to input, be careful not to connect the reversed positive and negative poles, and do not connect to AC power
- ★Multiple Protection Functions: short-circuit, over-current, over-temperature, over-power, over-voltage protection, charging anti-backflow protection
- ★Wide Application: It is widely used in ordinary power supply, battery charger, LED driving power, instrument voltage display, test counter, circuit test, power conversion. For more details, please read the user manual

## Questions & Answers

**Q: Can this can take an input of 5v 2.1a and output 30v 2.5a, and is the set output stable?**
A: No, not unless I have overlooked what would be a very valuable feature. 

If we assume 100% efficiency for conversion, 2.1 Amps at 5 Volts would give you only 0.35 Amps at 30 Volts, more realistically it would be much less than that since the conversion will not be 100% efficient
. 
30V * 2.5A= 75 Watts, 5V * 2.1A = 10.5Watts

I hope this helps. Please forgive me if I have misunderstood the question.

**Q: Can one use this to “trickle “ charge a motorcycle battery?**
A: The previous answer is incorrect.  Yes, it absolutely would.  In fact, its current handling capacity (~1A or so) would be more than enough to charge a motorcycle battery (12-24 hours), let alone maintain it.  However, since it isn't programmable, you wouldn't get the benefit of occasional absorption cycles to prevent sulfation.  Nevertheless, you could winter float a 300Ah 8D with this thing with no issues.

**Q: Does the usb in ports support data pass through to the usb out ports?**
A: Not supported, it is a power converter and does not support data communication

**Q: Does this display delivered current in real time?**
A: With multiple sets of fading LEDs, I'm observing about 2 current updates per second

### ⭐⭐⭐⭐ What an amazing little device!
*by A***U on September 20, 2019*

This can power DC devices which gives you control of fast/slow you want things to go. I control a pump and this works flawless. Update: Directly to the battery is fine. I had the Red USB power blow out/smoke during an ERR/OPP twice before I could turn it off and nothing was connected. The solar charger 12v output it was connected to fried the device.
