Note:

  • 1. This product is a 12V petrol car emergency starting power supply. It helps to start in case of emergency when the battery is low. Not all cars can be started. It depends on the size of the car, the condition of the car, and whether the internal circuitry of the car system is intact.
  • 2. This is suitable for small displacement (below 2.0 petrol cars), some vehicles cannot be started if the system itself is faulty and cannot be considered as a product quality problem 2. If the product swells and bursts due to operational reasons (such as reversing the positive and negative terminals, starting a 24V car, or hitting the car several times in a row without differentiating the battery capacity), it cannot be considered a product quality problem.
  • 3. As for charging other electronic products, the main function of this product is the emergency start of the car. Charging for other products is only an incidental function, not the main function. The product uses a high-rate polymer cell with a low conversion rate that is unmatched by ordinary rechargeable batteries. Contrast this with the fact that so 5V electronic products can be charged several times are not considered quality problems Start.
  • 4. Do not start continuously and do not start for more than 5 seconds. If a start is unsuccessful, you need to wait 30 seconds before starting again.
  • 5. New machines have false power and cannot be used directly. Please discharge first and then use fully (keep the power above 75). Charge and discharge at least once a month.

Hold up to tough wear - definitely recommend
Size: X-Large, Color: (001) Black / Black / Castlerock
These are my teens favorite socks. We've ordered multiple sets. Given that he tends to wear then as slippers I am really impressed with how they hold up. The extra large size is great for bigger feet. They wash well and I didn't notice any shrinkage, fading or pilling. This set is going to college with him.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.
