   With these below 0 temps I had a low battery! It would barely turn over! Sat for a week.
   Cold, cold, cold!!
   I put my 110V charger on it, but I couldn’t get it to start. Forgot about this Hererod charger I got for Christmas! It was charged at 99%.
   Hooked it up and started my 2016 Nissan Rogue like it was nothing!! It worked as advertised and didn’t drain even 1%👍
   Lifetime warranty and great customer service!
   Forgot to register the unit and Hererod emailed me a nice response quickly💯

   The EW40 has proven to be an invaluable investment for dealing with cold weather battery concerns. On Texas freezing weather, it has rescued me from unexpected battery failure, providing quick and reliable jump starts. What I appreciate most is its user-friendly design – anyone can operate it safely and effectively. Beyond its primary function as a jump starter, the unit serves as a versatile power bank with USB quick charging capability, making it perfect for keeping mobile devices powered during travel.

   The EW40 Jump Starter is amazing! It’s super powerful and started my SUV’s 9L gas engine without any trouble. It’s small, easy to use, and works great even in cold weather. I love that it also has a USB quick charge to power my phone or other devices when I need it. The black design looks nice, and it feels strong and well-made. This is a great tool for anyone to keep in their car—simple, reliable, and worth it!

   I have a lawn mower that is not easy to start in the winter and needs to replace the battery every winter. This winter I decided to buy a jump start. Now I just need to connect it to start my mower every time I use it, which is great!

   

8. Eric Zhang Verified Buyer – 11 February 2025

   My car’s battery was completely drained and I even cannot do remote control on my car. This jump starter solved the problem easily and quickly. After plugged in, I was able to start the engine just in 1 second. I would recommend it if you need one for your car. It works for most cars, trucks, and SUVs. The digital display is a nice touch, showing you real-time battery information. Plus, it doubles as a portable power bank, so you can charge your phone or other devices on the go. It’s recommended to charge more than 3 hours for the first time.

So far, I’m really happy with it—works great and does exactly what I need.
