Read 5 volts low at 120 volts ac compared with 2 other meters. Open the meter up and calibrated to match. if I didn't have to do that, I would have given it a 5.

Good meter, seems to be slightly off from what my friend's "fancy" meter reads.  But he's an electrician and I'm not, so I'm ok with it

The voltmeter itself is a nice basic digital meter with bright blue numbers. But BEWARE, the dimensions of the meter sent were not as listed on the ad. also note the stated delivery time.

This seems to be a nice little device, but I have to join the others who complain about the voltage being slightly off and the brightness (Lack of) of the voltage display.
I bought this because I wanted a Blue display instead of Red, which I already have.  I plugged it in, didn't see anything, and unplugged and plugged again. Only when I cupped my hand over it could I barely, BARELY see the numbers.
I have a gel battery in my vehicle, and the voltage of  my charging system always runs around 12.8 - 13.5. This reads 11.6 11.9. I have other meters that confirm it's off. Not a big deal, in any case.
The low brightness of the numbers is the reason for my 3 star review.
I do not receive things at a discounted price; I pay the regular Amazon price.

It's ok I mean it works but doesn't display the the different temperatures for different meats like previous gauges I have had. It's too much of an inconvience for me. I suppose I just need to remember once and for all lol

The meter seems to be accurate and works very well for what I needed.  If it continues to function as well as it does now I will consider a five star rating.

I figured that a $9 multimeter of this particular design probably wouldnt be anything special but I did expect it to work.  Come to find out, I expected too much.  This meter wouldnt give acurate readings on anything I tested.  At first, I thought maybe the batteries that I installed in the meter might be the problem.  They weren't straight out of a package but they tested fine on my battery tester.  In any case, I went out and bought new batteries-really good(and expensive!) batteries.  The meter still didn't work after installing the new batteries.  So I returned the meter.  Thank God for Prime.  Prime allows me NOT to be one of those people who say "it woulda cost me more to return it".  Anyway, I do NOT recomend this meter.  Not even a little bit.  I ordered and since received a different brand meter and its working perfectly.  Course I had to pay $8 more for it than this one cost but its worth having a meter that works.

Great meter Really good price.  I highly recommend!  After I wrote this first review And apron attempt to actually use them.  They will not calibrate so in my opinion they look and feel very impressive however looks are and were deceiving.  I hope this helps the next buyer

This meter looks great and is set-up well. Technical problems made my unit a non-
starter. It is very possible the calibration control was faulty. On the 10 watt scale the meter pegged hard and could not be brought back to the "set" line. The 100 watt scale was no more usable, again from a calibration control problem. The pointer could be placed on the "set" line if done very carefully but the setting was very erratic and not stable enough to make the SWR reading consistent. This is a problem that should have been caught some where in the assembly process. I believe this was an isolated occurrence and would not likely happen again but Amazon's return policy is always nice to have. Mark

Just opened the box and noticed immediately the description is wrong. The listing says "Etekcity UT61A Autoranging True-RMS Digital Multimeter" but the manual clearly says in multiple places the UT61A is NOT a True-RMS meter. It displays "effective" voltage.  (True RMS can display the real voltage of waves that are not a sine-wave, such as clipped or square or pulsed DC.) This is a sales/marketing issue, not a defect. The "D" and "E" models are True-RMS. I bought it for the True RMS feature, but got it on sale for $45, a great deal, so I'm contemplating keeping it.

I bought this hydrometer to check 12 batteries on my off-grid solar power system.  Not sure I like this tool.  The price is right and I may use it as a spare.  I am unsure how well this unit measures the specific gravity.  I ordered a nicer German made hydrometer, I'll be able to check for disparity in the measured acid specific gravity.

I recently received a Jellas USB Power Multi-meter ( model KCX-045 ) for a product review. In addition to the meter itself, a short USB extension cable was also included.  The meter itself isn't big, about the size of USB thumb drive or stick of gum.

I have tested a similar USB meter, so I was looking forward to seeing what was different about this meter.  The instructions state that it can measure the following:

Voltage/Current/Wattage: The voltage and current testing are common features on many of the different test devices I have used.  The wattage was a bit unique, but so far I haven't really found a need to measure wattage since I normally focus on mAh / Amps.

mAh: The mAh measuring capability was a feature I liked -- a similar meter I recently tested had the same capability, but before that the devices I used only measures voltage/current.  Measuring mAh is useful if you want to test the capacity of a USB power bank for example.

Time Usage: The time usage feature was interesting, in case you wanted to track how long it would take for something to charge or discharge.

The unit only has 1 button, but as long as you take the time to read the instructions it is fairly simple to operate.

I used the USB meter to do various tests, and everything seemed to work fine.  Based on my quick tests, removing power from the meter does not cause the readings to be erased/lost.  This is important, because one of my tests involves using a powerbank until it dies -- if I lost all my data when the battery died I wouldnt have an easy way to perform this test.

As an example of one of my tests, I used a the meter to measure the mAh of a small battery bank rated at 3350 mAh by using a 1A load and measuring until the battery died.  The measured capacity came in at 1800 mAh which was just 20 mAh higher than what I measured with a similar device.  Doing some quick math, 1800 mAh (or 1.8A) of capacity being used at a 1A load should take 1.8 hours ( or 1 hour 48 minutes ) to use the battery, and the meter showed 1 hour 48 minutes and 52 seconds so the expected and measured time seemed to match properly.

Here are the main points I noticed about this product:

Ease of Use: You just plug the device up between whatever you want to measure.  The fact it only has 1 button isn't too complicated as long as you read the directions.

Features: I have other similar devices that only measure voltage and current, this one also measure mAh capacity, wattage and time usage.

Size: The device itself is small, about the size of a stick of gum.

Bottom line: If you are looking to do some at home USB testing, this is a great option to consider.  I definitely plan to use this for future tests.

Update - increasing my review from 1 star to 4, since I found some wiring information on the internet. Still wish more info was provided for this multimeter or even a diagram at a very minimum would have been nice.

The meter itself looks like it will do a great job, but there are 3 connections to make on the back and since there are no diagrams or instructions, this is absolutely useless to me.

Well, I should have known better, but I trusted you guys.  I read the reviews and decided to go for it.  I don't need much, just something for light bench testing.  This thing is has a very cheap feel to it.  When I took it out of the box, the voltmeter was showing 5V.  No biggie, figured I'd just zero it with the zero screw on the front.  That doesn't work at all.  I put my meter on it and can see that the output is from 2.5v to 15 as it should be.  The meter will indicate to about 7V and that;s it.  I'm going to return it and spend a few extra bucks for something else.

This isn't a bad meter, but it doesn't give an accurate reading concerning the battery fill percentage.  It will show, say, 80%, then when a cloud covers the panels, it'll drop to 40% (or something like that).  Also when the batteries are full (the charge controller flashing to indicate so and this meter reading near 100%), when I disconnect the solar panels, it drops to something like 60%.  I know that's not right!  But I really like checking the input from the panels, which seems accurate.  So I like the meter, but I'm not sure I would trust ALL the information - I know the battery percentage can be wrong.

I like the meter. It's just what I was looking for and I would give it five stars if it didn't arrive with problems. I'm sure I could have sent it back and probably got a good one in return but that would take longer and I'd still drop a star for the hassle. After unboxing I was doing a functional check and found I had to adjust the ohm meter quite a bit to get it to zero when touching leads together. I also found the voltage reading low compared to my digital meter. Then I found the backlight didn't work at all.

I started to rebox it but figured it might be less work just to fix it. I found a bad switch was the problem with the back light and I had one in my supplies I was able to substitute. While I was changing the switch the ground wire that goes to the meter pointer came loose. I couldn't even see any solder on the end of the wire so couldn't have had much of a connection. I resoldered it and reassembled.

Now the backlight works and the voltage reading is spot on. I had to readjust the ohm meter pointer too so apparently low voltage and the need for high gain on ohm dial was caused by a poor ground from the meter. Anyway everything works great now. It's a nice looking meter and great for anyone wanting an analog meter.
