SUNPOW Lithium Jump Starter Battery Pack 2000A Peak 20000mAh (Up to All Gas and 8.5L Diesel),12V Battery Booster for Cars, Trucks, SUV, Portable Power Pack with LCD Screen and LED Light

Excellent item! I bought 2 of these, 1 for each car. I had a faulty climate control switch that was causing the blower motor to turn on at random times overnight draining the battery (2008 Chevy Equinox) I used this to jump start that car many times before we figured out what was draining the battery. When the battery was completely dead, pressing the Boost button this little box started the car every time. Very happy customer!

Excellent product. Jumps my diesel truck no problem. Keeps a charge forever and recharges quickly. We'll worth the buy

This little guy surprises me every time I use it. Was able to start a stone dead Kia soul that's notoriously difficult to jump with another vehicle. Only wish it would hold the float charge long enough for the alternator on the car to build a charge in the battery itself rather than just shut off the second it gets any voltage back. Incredibly helpful tool I keep with me in my vehicle at all times. Charges quickly using USB C.

I originally bought the Sunpow Jump Starter for my daughter after she couldn’t start her car after waiting a long time in the ferry boat line in the car holding area. I found out that many newer cars keep the running lights on after the engine is shut down. This is to allow the car passengers to get to the house door without having to search in the dark. The lights will shut off automatically in about a couple of minutes after the car door is opened and shut. However, my daughter never opened her car door, so the lights stayed on, waiting for her to exit the car. Because it was not dark, she didn’t notice that the lights stayed on. Also, she was probably listening to the car radio during this time. A ferry boat person then had to come out to her car to jump start it. I had always carried jumper cables in my car and helped others start their car after waiting a long time for the ferry boat or cars being stranded in a parking lot. Fortunately, I was able to move my car close enough to the stalled cars for the jumper cables to reach. When I received the Sunpow Jump Starter, I was impressed how easy it was to use and how quickly the car started. However, the small size instruction sheet that came with the Sunpow Jump Starter contained a lot of detail, so it could not be quickly understood how to set it up to start the car, especially at a time when a car needed to be started in a hurry. I also bought a Sunpow Jump Starter for myself, so I no longer had to carry jumper cables to jump start cars. I then made a Quick Start Setup Procedure for the Sunpow Jump Starter to keep inside the Sunpow carrying cases, if ever we needed to quickly start a car in the future. A few weeks later, I tried to use my truck which was sitting unused for several weeks. I discovered that it wouldn’t start. I then connected the Sunpow Jump Starter, using the Quick Startup Procedure I had written, and it started right away. It took about 1 minute total, from start to finish to start the truck, in less time than it would take hooking up jumper cables to the car and truck. I decided to include a copy of this procedure in my review so others can copy and print it out to carry in their own Sunpow cases. My daughter also loaded a copy of this procedure onto her mobile phone.

My son bought a 2011 Subaru Outback for his 1st car. It seems to have a parasitic power drain that quickly kills the battery. I wanted an easy way to jump the car any time and any where. The Sunpow JS02 has been great! It comes in a nice carrying case that holds the jump pack and all the accessories. I am not happy with the car having this known Subaru issue but this device gives me piece of mind that he won't be standard somewhere! We've used the jump pack about a dozen times and it's worked every time. I want to make sure it is always charged so we try to keep it at 100%. For that reason, I don't know how long it holds a charge but living in New England where the winters are cold, batteries have a hard time any way. My really only complaints are sometimes when we take it out of the case and turn it on, we get 2 different readings. It will show 100% for a few seconds then a 2nd number shows like 18%. This is without being connected to anything. Putting it on the car and connecting it to the battery, the car starts right up. Power will read about 96-98% after the jump but we still see that 2nd readout sometimes. I can't find any information anywhere about that 2nd reading. So idk! And that the cables connecting the jump pack and car are a little short - a few more inches of length would be nice. Otherwise, this device has been great. I would strongly consider buying again. 4- stars only because of that other reading.

This is my 3rd one. I got one for myself and my family. It works even to start on electric vehicles and that batter home charge for a long time. I hadn't charged my pack in 9 months and it was at 87%. It's really easy to set up and if you wired are incorrect there a red light letting know. It's it's set up correct the light turns green. Just hit the jump button and your set. The storage case is nice and keep the battery at a nice temperature even when the car may feel like a sauna.

Dudaba un poco sobre la calidad de este producto chino,pero una vez recibido note que es robusto;mejor aún,lo he utilizado en varias ocasiones en mi jetta(con la batería completamente "muerta")con excelentes resultados.

Levanta muy bien el arranque en diferentes tipos de autos, se puede usar el Boost unas 2-3 veces (No usar el boost varias veces seguidas) para cuando la pila esta muy muerta.

Excelente opción...funciona excelente para arrancar mi chevy 6 cilindros....

La vdd está excelente muy compacti me encanta

Funciona bien cuando la batería no está completamente descargada, me ha funcionado con arranques por falla de batería en una camioneta v6 y v4, aunque cuando la beatería se descarga completamente no la ha arrancado en dos ocasiones, esto en una Nissan v4. Es importante estarlo cargando al 100% para mejor funcionamiento.
