Review: Works as expected. - I only needed it to fix my Ryobi 40v batteries. I got an simpler one that broke almost instantly when tried to use. This was was robust. It has safety mechanism to shit off in case of problems. Current supply is stead and sharp, I measured with a multimeter. Very intuitive to use. My house is 110V and worked well. Volt adjustment was simple to use, one knobs for fast move and one for fine tuning. It was a good value. I may start buying all broken Ryobi batteries to fix them and resell 😂
Review: Made My Life Easier - This Power supply works great! I use it to simulate 12v power to manually retract electric parking brakes makes my brake jobs 100x easier only used it 4 times but it’s becoming one of my favorite tools! the quality of the buttons and dials are also very nice and sturdy. I love the voltage adjustability because some cars require 14-15v to activate park brakes. 10/10

## Questions & Answers

**Q: Is this unit a linear or switching power supply?**
A: This is a switching power supply as power if filtered through the transformer. Although it is rated for 110v input, inside the supply, if you feel comfortable with taking the cover off, there is a toggle witch will allow 220v input. They do this because it is easier to modify for other countries. It's older technology because it is not adaptive but how often would you change input. I do recommend taking off the cover and inspecting it. Mine came with the transformer not tightened down and some balls of lose solder bouncing around. Do inspect it before use but I have to say, it has been a pretty solid performing unit despite the poor assembly/final inspection.

**Q: How to increase brightness of dispay?**
A: No problem with the brightness of the display as of a new purchase November 2020.

**Q: What's the weight of the power supply ? Is it heavy?**
A: This bench power supply 60v 5A comes  with compact design and light weight , the host no less than 1.5kg.

**Q: Can it be used for electrolysis?**
A: It provides up to 30 volts at 10 amps continuously so it can replace a battery from 1volt to 30 volts and deliver up to 10 amps of current. If this would meet the power requirements of the electrolysis equipment then you are good.

### ⭐⭐⭐⭐ A good portable switching power supply with only a couple negative points
*by J***. on October 25, 2019*

This is a review of the NaviTech NP3010H power supply received on 9/23/2019. Low voltage and low current setting control is good. Turn coarse voltage or current all the way to zero when needing low values. Voltage adjustment: With coarse voltage = 0V, fine adjusts from 0.00V to 3.55V, with 0.01V precision Current adjustment: With coarse current = 0A, fine adjusts from 0.000A to 0.958A, with 0.001A precision Meter accuracy (Agilent 34411A 6-1/2 digit multimeter used for these measurements) VoltageSet VoltageMeasured 0.80V 0.799V 1.20V 1.194V 3.30V 3.291V 5.00V 4.991V 10.00V 9.983V 20.00V 19.994V 30.00V 29.901V 32.00V 31.906V CurrentSet CurrentMeasured 0.100A 0.0896A (25ohm load) 0.500A 0.4885A (25ohm load) 1.000A 0.9715A (0ohm load) 2.000A 1.9505A (0ohm load) 3.000A 2.9307A (0ohm load) 5.000A 4.8940A (0ohm load) 10.00A 9.82222A (0ohm load) 10.18A 10.0002A (0ohm load) Power supply noise (Tektronix MDO4104B digital oscilloscope with 20MHz bandwidth limit enabled for these measurements) 50.2mV peak-peak, 2.45mVrms (25ohm load at 12V, DC-20MHz, 100Meg samples/sec) 26.3kHz time domain switching peaks 6.02MHz and 14.1MHz frequency domain peaks Startup Transient Response 9.3ms 10-90% rise time from cold turn on 0 - 12V into 25 ohm load 21.5ms settling time to within 50mV of 12V (25ohm load) 19.8ms settling time to within 50mV of 12V (no load) No overshoot in either case. Note: Current limit must be set high enough to remain in voltage mode. If not, I did see 0.58V overshoot on the 12V startup transient. Shutdown Transient Response 89ms 12V to 0.5V into 25 ohm load 6.00s 12V to 0.5V into no load Shutdown transient response depends upon the load, and if there's no load, can take 6 seconds from only 12V. Front panel binding posts lack a center hole to thread heavy gauge wire through. Wire tends to slide off the binding posts even when tight. If you bend the wire in a half circle the diameter of the binding post, it holds better. This is the weakest feature of this power supply. Current metering accuracy is pretty bad at low currents, 10% error at 0.100A current set. Besides the two above negative points, the rest of the power supply performs very well for a switcher. I really like how small and lightweight it is. I'm using it for power input to a 3-phase stepper controller to drive a brushless DC motor, power for a 12V air mattress blower, power for a 12V compressor to pump air for car tires, and power for charging sealed lead-acid batteries on replacement UPS (uninterruptible power supply) batteries. When charging the valve regulated sealed lead-acid batteries, I use 14.2V with a current limit of 1A. The changeover from 1A current limit to 14.2V voltage limit is smooth as the current drops to less than 50mA @ 14.2V when fully charged.
