Looks nice, but accuracy performance is seriously lacking. When a USB device load is applied, the internal voltage loss is substantial. With a load of about 400 ma, the voltage loss gives an output voltage of less than 4 volts, with an input of 5 volts! Maybe if you only draw about 20 ma, it might not have too much loss. If I had known this, I would not of ordered it.

12V 75W 7Inch Car LED Headlights Modification Daytime Running Lamp for Jeep for Wrangler Harley
US$49.43 US$59.99

Ερ: I don't understand what the heavy Red wire connects to (and what it is for), the 3 wire plug shown, is all my original light uses

Allin The red wire contects to the daytime running light, this product not only use as a headlight, it also can use as a daytime running light.

Nice, I like it. English instructions are challenging to follow, but not to hard to figure out. Actual clock has a metal chain / keyring, instead of the pictured cord. I think I would rather have the pictured cord, but it isn't really a problem.

Nice but, what Chinese call a 4X size is about a 1X or maybe almost a 2X size in the United States. It will not fit me at all! I guess I will have to donate it to a Homeless shelter. Will Banggood give me a refund?

Works great, although the flashlight lets you dim the brightness, it does so with a slide control which does no't click into an off position when not being used.. It can easily be bumped and turn on when you are not using it.(dead battery) It does seem to be well constructed

I ordered this because it was claimed to be PNP, it isn't! PNP means it is Plug and Play. It claimed to be FPV, it isn't, it just allows space for you to add your own FPV if you want! There is not any transmitter controller supplied, which is part of being "PNP" ! No battery included! The only good thing I can say is, it arrived quickly. I expect a refund or whatever is needed to make it a PNP.

This is very bright. It offers 3 TTL control inputs for Red Green and Blue lasers. I assume that feeding pulse width modulation on these inputs should display most colors like a Tv but have not tried this yet. My only concerns are for safety. What kind of safety glasses do you use? Red Green and Blue at the same time?

Frustrating to operate because of only instructions provided are in Chinese. No other languages offered. Website (www.rolton.cn) also only offers Chinese info. It would be nice if someone could do at least a basic translation.

Camera seems to work nicely, but I can't figure out how to access some of the "features". I have not been able to bind to Bluetooth. The remote controller supplied is Bluetooth. There is not any English instructions for this or many of the other features claimed. What few instructions are provided, are hard to understand, their choice of English words seem to come from a translation dictionary. I have taken some 4k videos and 12 mp still shots with success. Nice quality images. I just wish they had hired a real professional English writer to write the small manual.

Looks nice, doesn't overheat, and works reasonably well, except the WiFi that is "built-in", gives me horrible internet connect speeds on the "N" band. I bought a separate USB adapter for the WiFi and that solved the problem. I use mine in my Van and display on a 12 volt TV, it seems well suited for that application due to its' low power consumption. This is all powered by solar panels mounted on the roof.

Ερ: This panel is not for charging 12 volt batteries, it is for charging 5 or 6 volt systems only!

Ερώτηση από prootz επί 2018-01-14 12:23:56

Ash2020 Open voltage, Voc is 14V. So it should charge 12v battery (maybe three 18650 batteries in series).

Nice, but it does not have voice control. It will light up blue from a sound, such as tapping a coin on the table. To me, saying that something has voice control, implies that it would respond to some voice command(s), this product does not.
