After reading some reviews, I bought 2 of those. They deliver. Its a general use product, so don't expect to measure 4-20mA signals, but it is not intended for that. Be sure to offset any dc current measurement before you start. I see a lot of complaints about this in the reviews, but dc current measurement offset is very normal and even stated in the manual. Would sure buy again!

Banggood offered me this saving card. I ordered it and could use it right away to buy my next purchase. Awesome service from banggood!

This is my 2nd diesel heater bought from banggood. It works right out of the box and heats up my garage perfectly. Now in use for about 3 months and running about 16 hours per week without any problems. I have ordered a 3rd one, exactly the same as this one. Install it using common knowledge and you have a trouble free operation.

Excellway 2200-7000W Pure Sine Wave Inverter 220V 50HZ EU Standard 12V/24V LED Display Power Inverter
US$74.09 US$89.99

Q: Note that the indicated power is peak power, not continuous power. The continuous power is half. So these inverters are 1500W, 2000W and 2500W inverters.

This boost buck converter works perfectly, has a very stable output even with big variations in input voltage, but can not handle 8 Amps as advertised. The unit gets too hot and will burn eventually. The heat sink is too small, or the efficiency to low. Therefore only 3 stars for quality. Use this unit at max 4 amps and you will have no problem. I have ordered already several of these units, but always with limited amps use (max 4 amps). If banggood would list this as a 4A unit, quality would get 5 stars.

I bought 10 of these to monitor my different battery banks. They work as advertised. You can see two of them installed in a big lead acid battery battery. I use these meters to monitor the voltage of the battery and the loss in the cables by installing several volt meters along the route. Would absolutely buy again!

This is the 3rd Unit I bought from Banggood. I like these units because they are very stable and have a long extension arm. Also, enough whole in the unit to allow charging cables and earphone cables to pass.

The unit is well built and works fine, but the flame simulation is not well done. The flickering is very aggressive and not random, hence the 3 star for "appearance". Would not buy again.

Absolutely value for money! I have build in the unit in my camper. I connected the aux in input to an external metal connector below the unit as you can see in the picture. Then I wired the aux out output to the aux in of the camper radio unit. The Bluetooth reception is perfect and connection is made immediately and is stable. To make sure my battery does not deplete when not in use, I installed an extra switch to disable the power to this unit. Would buy again!! The female voice announcing the the Bluetooth is ready, or connected or you have selected fm radio, is overkill, but not annoying. The usb connector you find on the unit can be used to provide power. So you can use the unit with 12V and with 5V.

It was broken after 2 days of use. I opened the unit to see what was the problem. The metal pin is spring loaded and that spring is "soldered" to the main circuit board and has come loose. You can not solder a spring, so very bad design. Not repairable. Its not because it is cheap, it only should last 2 days... Don't buy this item, there are better units availiable.

Q: Title says pure sine wave, this is false. Its a modified sine wave interver.

Asked by natwork on 2018-04-10 08:44:44

fleur4 I tested with an oscilloscope, this is not a pure sine wave.

These are good USB car chargers. Powerfull output. Be aware of the high resilient current when not in use. Its 20mA. Don't let it sit like that on your battery, or your battery will be dead after a while. But good quality, i have already 5 units installed like this in my camper. I can charge equipment everywhere :)

These ledstrips are very cheap, but are peaces strips soldered together. See the picture. Actually that is ok for me, as long as they work fine. And yes they work, but there is a big light fall off. I have measured the voltage after 5 meter, and if you start with 12 volt in the beginning, you only have 9.5 volts left at the end. The result is very visible light fall off on the strips with the leds considerably darker at the end of the strip compared to the beginning of the strip. I have solved this by injecting 12V onto the strip every 2 meters. So ok use for short distances (< 1m). For long distances, don't buy these. Because of this light fall off, and advertised max use of 5 meters, only 2 stars for quality.

The unit is delivered with an extra small heat sink you have to glue on yourself. Although listed as 5A, i would only use it at 2A max. Even with the heatsink, the unit gets very hot above 2A with risk of fire. Therefore only three stars for quality. If banggood would list this as a 2A unit, quality would be 5 stars. You can see in the picture where I glued the heatsink. In the background you see the connected ledstrip.

This is the second time I order this phone holder. Very good and stable device. It can hold a phone in both landscape and portrait, but also a 10 inch tablet on the "short side". I use it in my car to fasten the tablet as a gps system. Very pleased with the item!

This little board is the perfect solution to build your own power pack. It comes with a built in flash light. A little switch lets you active the background light of the display or the flash light (double click). The percentage of the state of charge is rather accurat. The charging stops perfectly at about 4.1-4.2 volts. You can not however charge and discharge at the same time. The discharge gets priority (your connected phone will charge, but the powerpack will not receive charge input from the connected charger).
