9 Heating Pads USB Electric Heated Vest Jacket Warm Body Warmer Pad Winter Thermal
US$29.99 US$54.99

Q: There are 9 heaters on sale, but this is not true. there is only 1 on the back neck and 2 on the front pocket. there are 3 pads in total, why do you give false information....?

Asked by farukerozan on 2020-02-22 04:46:38

Alain I'm also disappointed by this, I left a review confirming only 5 heating instead of 9 and my review is not published!!I'm starting to be less confident in Banggood's reliability.

Product is working as expected, able to identify fingerprints better than the old system I bought a few years ago. I coupled it with an arduino nano with the Adafruit library. Will probably buy more if there is a discount price in the future.

The device can store up to 16MB files in mp3 format, in stand alone mode it is possible to select 5 different files. There is an integrated amplifier and a 8 Ohms speaker can be connected directly. Perfect for small devices. The files cannot be copied directly from the explorer, there is a dedicated program to upload the files on the on board memory.

Bought the 6mm to couple a CCD to a light spectrometer. The lens is very low distorsion and the infra red are perfectly visible, this point was mandatory for me to build a spectrometer 350nm - 1000nm. This lens is not suitable for normal visible light, the colors are distorded as there is no infra red filter. Highly recommended for some applications like night vision or infra red.

Looks great, the plastic and construction are high quality, really amazing for this low price. The bad side is the real torque, I was unable to unlock a 200N.m bolt, it was a success only on a 100N.m, so this tool is perfect for auto tires or woodworking. Don't expect to unlock a wheel bearing shaft with it, even if they are usually torqued at 240N.m. Measured no load speed is 2200 rpm, not 4000 as written. At the end I'm very happy with this purchase, I will have a lot of use where I can't use my bigger pneumatic impact wrench.

Not 24W, real power is rather 6W, current is 0.55A on 12V. Looks like there is an internal limitation power control circuit, if you set 11V the current is increasing. Measured peak wave length around 838nm. Auto power on cell has correct sensivivity. Overall a good product is you can accept a 6W power.

Works as expected, charge starts at 5 Amperes and decreases until the battery is fully charged. Good value for the price.

Pro : easy to use, low price, measure can be repeated with exact same value, calibration easy to perform, fast reaction time about 30 seconds. Cons : cannot measure under 400ppm, battery charge last only about a day, alarm trigger value cannot be changed.

Compared to another RG316 I had this cable shows a 4dB loss at 4GHz, Frequency attenuiation curve for 10 meters length : -3dB at 100MHz -10dB at 1GHz -15dB at 2GHz -19dB at 3GHz -26dB at 4GHz

I measured a return loss of -18dB at 1GHZ but only -12dB at 2GHz and -10.5dB at 4GHz. Other dummy loads I have in my lab still get -22dB at 4GHz (1.2 :1 VSWR).

50 ohms load is defective, I tested a 1.5 VSWR that is not so good. The dummy load measured with an Ohm meter is indicating 74KOhms. Did a quick test and the antenna seems not better than my 11dB patch.

I am a ham since a long time but was never able to afford a VHF/UHF generator, until I found this device. The internal 25MHz reference is not very precise and stable, I had to use an external 10MHz reference to get a precise frequency. This device is very handy in the ham lab, from receiver tuning to antenna construction.

First try resulted in a failsafe at 150m, very disappointed. Today I tried to investigate the problem and found that the delivered antenna does not work, attached is a measurement of the SWR with the Frsky antenna and a homemade dipole. I hope that the transmiter has no resulting damage from this bad SWR antenna, will try soon with my homemade dipole and hope to get a normal range. Frsky should improve the quality control.

About 15% of the image is not well focussed on the left and right part of the image. Even with the narrow angle of view the left is still fuzzy. In an ambient temperature of 20C the camera reaches is 59C in open air, thus this might be a concern in summer if the case is set in foam planes. Well suited for light models, for 25 grams more I would prefer a Mobius is weight is not a matter.

Bought it to use in a flight controller, tested with my favorite SD tool and failed the check test. I can't use this card in a critical device such a flight controller that might result in a lost plane model.

Very bright, use real xenon lamp. After a while I checked the temperature with ambient at 21C the lamp is at 36C and the DC converter is 30C.
