This is an amazing power supply! It is working great and has many features, in a modest price. I have already a homemade transformer (from microwave oven) and it is actually a perfect match inside the box and also in volts (almost 70V)! It also includes an external thermometer and I measure the temperature of the transformer. A have only few complains: having only 6 amps is somehow limited, I hope for more in future models. The banana plugs are not the best. Having led in some buttons is very good, but the numpad has no lights. Other than those minor things, I like it and I suggest it! I also suggest the other power supplies from this company. I have the buck/boost model https://tinyurl.com/wbpqvbe connected to an old 12V computer power supply and it is working flawless for years now, as my main bench power supply for my electronic lab.

It is bigger than i thought it was, around 10cm square. In general terms it is acceptable. My complaints are: the light is always off (after 8 sec) and cannot see unless i press the top button or enable the switch and make some noise. Also the viewing angles of the LCD are poor, you have to look from the front or 45 degree left or right, in any other angle you cannot see clearly. If you want something simple then it is acceptable if you want something good look elsewhere.

Small and simple circuit, it works as it should. The switch totally cuts off the circuit from the battery, so no battery drain. A little bit expensive. You only have to press once, no extensive hold is needed. I have marked R1 in the image, but you cannot see that with naked eyes. Make sure you have the version of your battery pack (1S-5S). It would be great to buy 1 and use it to various voltages, but you cannot do that with this one. If you want something with multiple voltage capability, this this is the only one i was able to find: https://www.banggood.com/Power-Indicator-Display-Led-Board-For-2_4V-20V-Lipo-Battery-p-1094009.html?p=3B12018498528201701G

It works fine with 10W LED floodlight. For LEDs the maximum recommendation is 18W. You have to connect it in series with the load like the image. I prefer to connect it with Live, but either way it works. Unfortunatly it is not waterproof... maybe inside a waterproof box??? If you want something more powerful check this: https://goo.gl/YrudoV

I brought this charger/balancer form Banggood T610 - https://goo.gl/KLukPU and i am very happy. But what about over-discharge protection? So, i brought three 2S protection boards. I have tested the cutoff voltage in all 3 of them and they are at about 2,837V (great consistency!). You have to apply charging voltage to overide the "lock", you need 6,45V or more. I also did the same test to this 3s protection board https://goo.gl/eGaZwc it is also good.

I have tested the cutoff voltage and it is at about 2,33V. This is ok if you are draining your batteries with high current, because you have a fair amound of voltage drop. But it is low if you are using low current. You have to apply charging voltage to overide the "lock" after the over-dischard cutoff and the voltage must be above 2,9V in each battery to do that. I also did the some tests to this 2s protection board https://goo.gl/kJ4qX4 and it is really good and cheap.

I have measure all 10. Real dimension 27x16mm. Real Capacity from 2080 to 2230uF. Very low ESR 0,06-0,07 Ohm. If you want double the capacity with the same price and size but lower voltage, check this set: https://bit.ly/2IWJdwp

I have it for a month now and i did many tests. This device is excellent, especially for the money. There are 2 smaller models without resistive touch screen (60W/6A: https://goo.gl/2akSnE 120W/10A: https://goo.gl/pV6sme ) and 2 bigger models with touch screen: (160W/12A: https://goo.gl/wGBUaE 300W/15A: https://goo.gl/Y6eBZo ). You can also download the manual and future updates from the original site here: https://goo.gl/ke4W85 The plus for me are: it can work with 30V DC input max, it can be used as adgustable PSU, touch screen with good intuitive software, great price, good power output (120W/10A), supports LiHV batteries, nice charge/discharge graph, 6 extra pins: 2 for external temperature sensor, 2 for servo testing and 2 for software update. Some minor negative are: you cannot fit the standard 5,5/2,1mm connector, it has a 5,5/2,5mm connector (it is actually common to laptop PSUs), the battery voltage reading is fluctuating usually +/- 1V but sometime +/-3V (this is software problem and some others that follow, i hope it can be fixed with future updates), the capacity measurements sometimes are wrong (ex when you charge with 1Amp and then discharge with 2Amp, it calculates capacity for 1Amp discharge... you can fix that by reseting the device, but it is annoying) and finally when you charge more than 3 hours the graph is loosing the calculations.

Great size for my arduino projects, not to small not to big. The spring is soft and works really well. The top is actually made from plastic but it is strong. If you want a similar looking ON/OFF locking switch, this is the only i was able to find: https://bit.ly/2IUn9CD

Good looking flashlight and small price. Quality is acceptable for this price. If you dont care for highest output, it works better with AA than 14500 because it does not overheat. Zoom is a good option to have. The clip is very flimsy. It has no memory and 3 modes, so you dont know what mode you are into when you open it and this is something that i don't like, it is confusing. For simple use is ok, but for serious use give abit more for a better one, like this one: https://bit.ly/2lgAuaR

Original battery SAMSUNG 2600mA (26J). Here is the original pdf https://bit.ly/2t5U2CW and here is an independent test https://bit.ly/2M4j78E both without protection circuit. Testing with the protection circuit in a flashlight, it can go to around 2A, without the protection around 5A. If you want extra juice, i highly recommend the panasonic 3400mA https://bit.ly/2K4wTdO without protection. Note: the length of this SAMSUNG protected cell can be a problem, for example it cannot fit to this case https://bit.ly/2I33lIu even if there is a spring, so be carefull.

It a hefty and impressive flashlight! For this price it is an excellent product! The reflector gives a uniform light with the ability to zoom. In general, it is for close distance, very good for indoors. The black color is scratched relative easily. It starts always with high (i have messured 1,25A) and you can go less just holding the button. You get a double flash when you hit minimum/maximum. I would say the minimum is medium intensity, don't expect low. After 15min in highest mode i have meassured 55oC temperature, around the same in 25min. Actually you cannot hold it in that temperature, so i would recommend few minutes of working in high mode. It has a green led for battery status and you get a red blinking when the battery is low. In my battery (panasonic 3400mA) i got red blinking at 3,75V and i recharged to full with around 1200mA so you have plenty of time when you see the red blinking. I did't test the USB charging, i always charge my batteries with a proffesional charger. In the photo i have for size comparison a BLF A6 ( https://bit.ly/2yhuWGu ) which i consider an excellent flashlight and a smaller AA/14500 ( https://bit.ly/2K1ADgw ) with a very good price.

Very impressive little flashlight, small and light. The low is REALLY low which i like. The medium is OK and the high is acceptable. The twist top isn't my thing, i prefer clicky switch. Sometimes it register 2 times in a single twist. The strobe activation is... stange. It is actually activated every other cycle, so i need to twist 7 times! Mine has a memory which is really annoying. I like better the titanium version, here: https://bit.ly/2ID2NOW

I bought 2. The capacity is much lower than the advertising. I have measure them 13820uF/0,04Ω and 14490uF/0,03Ω. At least for the price are better than those: https://bit.ly/2IBhXnH

Nice surprise when i saw that the insulation is silicon! Very flexible and excellent quality. It is like 26AWG and it is NOT for insertion to a breadboard but to solder to a perfboard (this is a misunderstanding of words). If you want bigger size, this is an identical wire: https://bit.ly/2kdK0Lj

This is an ON/OFF locking switch. It is made of plastic and looks strong enough. You cannot tell if it is ON or OFF by your eyes but you can feel the spring loose when it is ON. If you want a momentary switch to match this one, with similar size and color check this: https://bit.ly/2GHW6p2

I use it for 2 months now. It removes a lot of material and i always wash the knife after use. I use it mainly for making a bad knife back to sharp. Be gentle and dont use force or else it will damage the diamond surface. It will last you forever if you know what you are doing. On the other hand, if you used to sharpen your knifes very often, stick to typical metal rod like htis one: https://bit.ly/2rWLy0K
