DrMichael I've measured this at 0.35mA (348uA) with a multimeter in series with a Li battery (at 3.98V). It measures the same whether or not the Output USB is switched on.

aecarcu Bubble wrap hasn't come to China yet. Worst packaging ever. I don't recommend buying this.

Very simple MOSFET with input isolated by an opto-coupler. Has wide power tracks and screw terminals for control input on one side and power /load on the other side of the board. Very useful for interfacing digital level signals to high current/voltage switching. Nicely built and well marked connection points.

This is one of the best USB to TTL adapters and I use it all the time. The board has a mini USB connector (make sure you have the right cable for it). I soldered the 90 degrees 6 pin connector it for general use. There are also many other possibilities to connect pin headers/wires to the board. very important feature is the on board jumper which must be set correctly for either 3.3 or g Volts, in accordance with the controller type you use. All in all this is a very good value for money and I recommend it to all users.

Very good quality. This is a compact power receptacle for 10A with a replaceable fuse holder. Access to the fuse is very easy. There is also a rocker on/off switch which clicks into the receptacle. All in all this is a very good value and also looks very professional. I will recommend it willingly to interested people.

This smd practice kit is exactly what is required for practicing smd soldering. It contains all types of smd components with the most usable sizes for practice training. The board also features various testing points that enable the user to verify the quality of his/her work. The board is very densely populated and has many many components to solder and practice on. I like it very much and hope to learn from it and enjoy it very much.

The charge board is very well constructed. It has sturdy battery posts that hold the 18650 cell firmly in place. Charging is done from the usb port. The board supplies 5V through a usb port and also 5V and 3.3Volts directly from the board. The on/off switch is very handy too. All in all this is a very well engineered product. It is very useful as a charger and as part of any battery powered diy project. I will recommend this product to my friends.

These tweezers turned out to be a very good value for their price. The sis tweezers are very precise and of good quality. I use the set mainly for electronics work and other jobs that require handling of small items such as tiny screws. The tweezer set includes tweezers of various lengths and tip sizes, which are useful for a large range of jobs. The tweezers came in a nice utility bag, each in its own compartment so they can be kept together, carried together and stored in an orderly way. All in all this is one of my best tool purchases and I recommend it to all my friends.

The DM01 arrived well packed in two separate boxes: one containing the camera and LCD and the other containing the metal stand. The assembly was very easy. After only 3 minutes I was able to look at my SMD boards and see all the tiny details. The stand is quite robust, but the ring into which the camera is inserted is a bit loose. This product is very easy too work with as it allows a good distance from the object to the lens. I have not yet tried the connectivity to the computer because I have not received a link to their viewer software for Windows. All in all it is a very good value for the price and I will recommend it to my friends.

The product arrived well packed and in good condition. It is exactly as described in the site. The silicone pad is the perfect size for me. It is strong and there is a very good feel to it. I can solder directly on it without harming the table top. the pad itself remains clean and is resistant to the heat. Very good product and good value for the price.
