2. Purpose: test spark plug performance and ignition strength
3. Application range: 12V gasoline engine automotive spark plugs
4. The dual-hole automotive spark plug tester has two test holes, which can test two spark plugs at the same time. If you suspect that any spark plug is not working properly, you can do a comparative test to make an accurate judgment
5. Test principle: In the automotive ignition system, the high-voltage ignition coil generates a high voltage (more than 10,000 volts), and the spark plug leads it to form a high-voltage ignition coil into the cylinder engine. The spark between the spark plug electrodes ignites the mixture. The detector can distinguish good spark plugs from bad spark plugs according to the intensity of the spark
6. Turn the key switch clockwise to turn on the tester, and the indicator light is green
7. Close the protective cover, insert the adapter into the side socket, and connect the tester to the power supply to turn it on
8. Turn the switch clockwise to adjust the operating frequency between 1000rpm and 6000rpm/min. The higher the frequency setting, the stronger the spark.

Soft and fluffy after a wash & dry
Color: 02 Ashley Blue, Size: Throw XL (50" X 70"), Color: 02 Ashley Blue, Size: Throw XL (50" X 70")
Perfect, lightweight and warm. I got this for a chaise that I use. It’s not thick, but enough to keep you warm and cozy if you’re just reading and relaxing. I washed it and dried it as soon as I took it out of the box. It fluffed out perfectly, so don’t be fooled by the flattened squishy blanket that arrives. It doesn’t shed, which is a bonus.

High Quality Comfort!
Color: 01 Sage Green, Size: Queen (90" X 90")
This is definitely one of the most comfortable blankets I have ever owned. The material is thick, soft, warm, durable, and resistant to shedding & fibers breaking off. All of these favorable qualities work together to create optimal sleep conditions, and I would say it protects against cold temperatures in the environment (natural air & A/C, for example) very well. It is SO extremely cozy!!! It has become a comfort item of sorts, as well. It fits my Queen-sized bed absolutely perfectly. I've been searching for a blanket to fit my entire bed, and this blanket most definitely is the one.
When this blanket is nearby, it's nap time!
I love the the slightly raised texture of this blanket's material, and the checkered pattern adds a subtle, yet stylish touch to its overall appearance.

Loving my Bedsure Blanket
Color: Cream, Size: King (108" X 90")
I love this blanket. It’s for summer use & is the perfect weight. I feel both cozy and cool! Plus color & size are as shown. I washed it immediately and it was easy & came out soft; no shrinkage or shedding in the dryer.
