There are also reviews that warn about the loading unit. Because I expect it will fail a UL or CSA test, I want to go into excessive detail about it. 'O' does not mean 'off'. When one 5W load resistor is on, it means it is When both are set to 'I', they are Each resistor has a watt rating of In spite of this, their wire-wound ceramic resistors are designed to get very hot, so they need an extensive amount of ventilation to handle. The photos I took were taken with a (very) low end thermal imaging device. According to the temperature readings, I am confident in their accuracy. In a little experiment, I used a very accurate immersion thermometer for the job that wasn't designed for this purpose, but did surprisingly well. In the top right corner (? ), what is in the center? () photo was actually taken at the end, right after the power was turned back on and it started You'll see things in a visual way There is only one I was not willing to handle the USB connector because the digital temperature display indicated it to be too warm. This image of the 5W switch (switch 'O') has the cross hairs on the resistor that is off, and note the maximum temperature at which the cross hairs were drawn It was made shortly after the temperature passed 200°C, about 400°F, that the 10W image (switch '1') was made. It was hot enough to bake dirt off the resistor and put my mind at ease about the vinyl pad on which it is displayed. There is no doubt that the load unit soaks Take care when using this and add a fan if necessary. Be sure to read all of the warnings in the manual!.

There is no doubt that the product Okay, I'll give it to you. Your device goes on the other end. Plug it into a USB port and it is ready to go. I was mostly interested in the throughput and voltage numbers on the screen, as well as the enumerated information. Although this unit doesn't look or explain what it is showing, it can be taken as a joke. A hardware or software engineer might be interested in I would not have been able to make the most out of this but you might be It would have been helpful to have had more information on the circuit board that came with the device. I assumed it would be a dummy load, but I would have appreciated more information on the circuit board.

It is very easy to use. The color screen that comes with this makes it very easy to see clear instructions, and the device is easy to use. I used this to test the current from a charging port to my electronics in order to verify that the rating given by the manufacturer was accurate. This is an extremely pleasant surprise, considering the price. Upon placing my order, the item was shipped quickly and arrived on time as expected when I expected it to. It also comes in a padded container that is really nice to have. It has measured these types of metrics well and I would recommend it to anyone looking for a device that measures this kind of data.

AVHzY made the AT34 + load available for me to use in A great tool to check relative battery capacity (for phones and external batteries) Verified raw numbers via multimeter, but have not verified the accuracy. In three attempts, the battery exhausted 1718, 1734, and 1735mAh - when it was charged and discharged three times. In the AT34, charging is reported in trickle mode and sometimes burst mode (0). As opposed to zero, 300A. In Figure 001A, after a battery seems "done", follow these steps To compare them properly, you must know the exact time when you measured the current. If you measure it after an empty battery, the current never sinks to zero. The tool was used to diagnose a bad power circuit on a phone (screen was broken, wanted to check for further damage without replacing screen - the device was easy to use and effective). At some point, the AT34's screen turned black, showing that something was seriously wrong (somewhere). I like how it came in an impressive tin for storing it. It might not survive a stomp on the plastic window, but it could protect loose metal tools from nicks if kept with them.

In addition, I was wondering how long the aftermarket cables, especially the longer ones, do not cause any signal loss. As soon as current is run through it, this little device comes to life. What you need to know (Voltage & Current) An amplifier's display (amps) is easy to read and understand I see. It confirmed how well I was charging my devices. Interesting, it was verified that if the cable was cheap or poorly made, it'd usually reduce the amperage, but if it was better, it wouldn't. There is a tendency for the circuit of the load tester to get very hot quite rapidly. Certainly it does more than I've used it for so far, but I think I've used it well enough Yet I am not an engineer & I am not trying to fix anything There is a minimalistic style to the user guide that seems to be written for people who are aware of They both came in sturdy metal storage boxes and there was a view-through window to let us see what was inside. It's a good price point for me.

I compared a few of them, and this one piqued my interest because of the I believe this is accurate to the best of my ability. With a new 10000mAh (rated) battery completely drained and recharged with this meter inline, it displayed 10251mAh, used, which is pretty accurate when considering there's also going to be some power loss during charging. In addition to using this to describe the countless charging outlets and wires in our house, it has also helped me describe the cabling that we have. Several outlets are close to their ratings while others are at or near their ratings. The expected result has been reached. A shorter charging cable will result in a lower loss of energy. Additionally, the package is very good, and I had no idea that there was a test load included. *Edit
We lost our first one, so we ordered a new one.

In order to test chargers, a "dummy" load comes with the unit. This load draws 1 or 2 amps. This device allowed me to check the voltage and capacity of two convenience chargers that I suspected of not working properly. It is really a nice display unit- I did not experience any issues. Four different orientations are possible based on the orientation of the screen. An individual button on the back is used to rotate the unit.

In some cases, a magnifying glass may be needed to see some of the text if your eyes are failing you. Still, I think it is an excellent piece of equipment. I think it is not very safe to use because it gets very hot when running, so it should be used cautiously. Even though the instructions are very basic, if you have some experience with basic electricity (like P=IxE), you may be able to figure it out. A tester outfit such as this one is hard to beat at this price.
