KWS-V20 USB Current Voltage Capacity Tester Volt Current Voltage Detect Charger Capacity Tester Meter Mobile Power Detector
US$5.99 US$18.99

Q: How much power, in mAh, does the meter itself draw when being used? Or does the mAh displayed add together the power used by the display and the power drawn by the attached device?

SandyMan69 Very good question never even thought about that. I could not find anything on this. It has an LED for back light, LCD display and logic Im guessing less than 20mA. If you bought two you could plug one in to the other and the first one should tell you.

These are excellent and I’m on my third order of 2. I use them in the bathroom, kitchen and home office to give me light at night rather than leaving lights on. 2.5 hr charge. Last about a week.

Works great and is precalibrated. I tested with local tap water and the pH came out close to what I expected - 7.3. It does not include the LR44 batteries and needs 2 of them so make sure to order some or have 2 ready. Highly recommended.

1 Pc Perpetual Motion Instrument Spherical Pendulum Orbital Revolving Ornament Toy for Home Office Birthday Gifts
US$15.99 US$19.99

Q: The instructions say "This globe toy is powered by four AA batteries, after installing the batteries, when striking the middle part, the perpetual motion instrument will keep swinging until the battery runs out." I have installed fresh AA batteries and start the toy spinning but it stops after less than a minute. What does 'striking the middle part' mean? The middle globe?

Asked by VancouverDoug on 2019-11-26 04:57:12

Chordmerchant It means to: Start the middle section into motion.

A great deal and it proved to be very easy to setup. It automatically reconnects with your phone the next time you start your car and with one push of the play button, your streaming music from your phone to your car's FM radio.

This is a fantastic gizmo and, as always with Banggood, the price is amazing. Setup is pretty easy but make sure to configure it with the engine running. Audio quality was excellent at 104.2 FM which was clear where I live. I haven't tested the cell phone or the micro SD card parts yet but so far it works perfectly paired, via Bluetooth, to my iPhone 10x. Restarting was a breeze and all I needed to do to start listening to my music again was press the main control knob. too cool! I park in a less than secure area in a big city and keep my car unlocked to avoid paying $400 for a broken window. I'll order 2 more of these as spares. Great device and I highly recommend it.

Gorgeous. I’m always reading a collection of books simultaneously and I’m very tempted to by more of these. They get through airport security just fine.

Beautiful and elegant. Much nicer than the boring rectangular ones I grew up with. I gave a set to my sister, a big book reader, and she loves them!

A nice big display and 100% visible in direct sunlight which was why I bought it. Highly recommended for rooms that are bright during the day.

VancouverDoug Thankyou for posting this! The FC16_HW hardware type fixed my problems. :)

Great display! Took me a while to figure out how to set it up, but it was quite easy. As mentioned in the previous comments; download the “https://github.com/MajicDesigns/MD_MAX72XX” library into your Arduino IDE. Open the “MD_MAX72xx_Test” located under Examples. Change line number 25 from “#define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW” info “#define HARDWARE_TYPE MD_MAX72XX::FC16_HW”. You can read the explanation of the different hardware setups in file “MD_MAX72XX_lib.h” located in the library. Do not make any changes to “MD_MAX72XX.h” in this latest version. If you combine it with the “Tiny RTC I2C AT24C32 DS1307 Real Time Clock Module” (https://www.banggood.com/5Pcs-Tiny-RTC-I2C-AT24C32-DS1307-Real-Time-Clock-Module-For-Arduino-p-951559.html?rmmds=myorder&cur_warehouse=CN) you can create a nice clock!

The quality of the product and the design is great but I the model I received does not fit a 9.7" iPad. It's much too small.

Fast delivery and the headphones audio quality and weight are perfect. Nice rich base and a great volume range - louder than my factory issue iPhone headphones. The mic works fine but, like all headset/mic combos you'll need to raise the mic closer to your mouth for best quality,

These glasses are amazing. I've tried all sorts of expensive bifocals and cheap reading glasses but this design is amazing. I've only used them for a few hours so far but my eyes have adjusted fast and EVERYTHING, near and far, is in focus. I'm completely amazed and will be ordering a second set today. For the price of a pair of drugstore reading glasses, you can get nearly perfect vision.

Very cool product and the second digital fitness tracker I've bought from Banggood. The first one was great but a bit bulky and the battery only lasted a few days. This one is nice and slim and the battery lasts forever. The only negative is the app for iPhone could use more features and a better English translation. Hey Banggood! I write iPhone/iPad apps for a living. Call me. :)
