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. Read more
I recently had a dead battery at work and had to call my mom to help me jumpstart the car. After that, I decided to get a small but powerful jumpstarter that could fit in the glove compartment. It's rather compact with no concerns; the flashlight is useful in low-light situations, and the cords provided outside the jumper wires can be used to charge a dead phone in an emergency or other electronic components with an adapter. Overall, I'm satisfied with this product ☺️. When the time comes, this will be a really useful tool to keep my car running. 🙂 Read more
Excellent product. Jumps my diesel truck no problem. Keeps a charge forever and recharges quickly. We'll worth the buy Read more
I bought this starter in 2021. this year (2026) I was stranded at my house after the 1st nor'easter for about 3 months (issues with the city not plowing my street). My car battery has a habit of not keeping enough of a charge to start the car in cold weather. This was the 1st time that I've attempted to use the Sunpow as a jump starter. It started the car on the 2nd attempt. I'm glad I had this device inside my car. Read more
Well it came 78% charged which is great. I charged to 100% and put it in my trunk which is where I plan to keep it, in case a jump start is needed for my vehicle or somebody else. It has a nice and solid storage case with ample room for all its accessories and instructions. I like the fact that it has a display that shows percent charged rather than just an indicator light for charged or discharged. So far so good, but the real test is how long does it hold that charge( how frequently do I need to recharge it) and how well does it work starting a car with a dead battery. I don’t know the answers to these questions yet. My first impression is that it looks pretty good. I gave it 4 stars instead of 5 simply because I don’t really know how well it work yet Folllow up- I have had it for over a year and it is great. It holds a charge really well. In power outages it is great for keeping my cell phone charged. Recently, my grand daughters’s car had a dead battery. This fired it right up. I gave mine to my grand daughter and bought myself another one just like it to replace it. I am upgrading to 5 stars now that I have experience with how well it works. Read more
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. Read more
Well designed and built. The first was purchased for the pick up 2 years ago and has stood up well. I used it once and jumped the pick up OK. I bought the second for the car. Same unit. But was missing the USB wall charger. I was returned. Read more
It just keeps on working for us. I think i purchaded the 2000a jumper, which is a lot of amps. When it says "all gas", they might as well have actually said "all gas no brakes" because it will pixs your, know it all gotta have the expensive name brand everything, neighbor off. Ive used it to jump vehicles from v8 boats to v8 suvs to v6 cars. As long as the battery is in working condition, not corroded and can still hold charge, it will work for you. Sometimes you gotta use the little boost button and try a few times, and make sure the device has plenty of charge. Some start ups can drain this thing in an instant so I think they might be right about the 2000a crank start abilities. Why do cars even need massive batteries if they can be started using something this small and ($70) and light weight it will then not only pixs off your know it all neighbor, but it will also pins you off also.
