016 Jump Starter 3500A Peak, Jump Starter Battery Pack up to 50 Jump Starts, 12V Jump Box for Car Battery, up to 9.0L Gas and 7.0L Diesel Engines, Jump Starter Portable Power Bank, Cocy-016

The Gillaway 016 Jump Starter is a compact but mighty device that can be a lifesaver when your car battery dies. Here's a breakdown of its key features:Pros:Powerful Cranking: With 3500A of peak cranking power, the Gillaway 016 can jump-start most gasoline engines up to 9.0 liters and diesel engines up to 7.0 liters. This makes it suitable for a wide range of vehicles, from sedans to SUVs.Portable Design: The Gillaway 016 is small and lightweight, making it easy to store in your glove compartment or trunk. It won't take up much space, but it will be there when you need it.Multiple Jump Starts: Gillaway claims the 016 can provide up to 50 jump starts on a single charge. This is a great feature, especially if you're prone to dead batteries or drive in extreme weather conditions.Portable Power Bank: The Gillaway 016 doubles as a portable power bank, so you can use it to charge your smartphone, tablet, or other USB devices. This is a handy extra feature to have on hand in case of emergencies.Cons:Limited Information: While product descriptions mention peak cranking amps and engine capacity, it's difficult to find details on battery capacity or recharge time. This can be a deciding factor for some consumers.Brand Recognition: Gillaway may not be as well-known as some other jump starter brands. While customer reviews can help assess quality, some users may prefer established brands.Overall:The Gillaway 016 Jump Starter is a powerful and portable option for keeping your car on the road. It offers enough power for most vehicles and the ability to function as a power bank is a valuable bonus. However, some users may want more information on battery capacity and recharge times before purchasing. It's also worth considering established brands if that's a priority.

What I do not like is unlike my previous jump box is this one does NOT have a boost button. With my previous jump box, it had a boost button and I had to use it in order for the jump box to start my SUV. I'm hoping since this one doesn't have the feature it will still have enough power to start my SUV if I find myself in need of a boost. What I like about the jump box is it's compact size and how easy they are to use. While I'm happy I don't have an immediate use for it, I feel comfort in knowing I have it available should I need it. It came charged 56% out the box but I'm currently charging so I can put it in my car. I will check the power in a week or so to see if it holds a charge. My previous held excellent charge even after using, it would still be at 100% charge. I hope this one meets or exceeds the previous. The stats are the same as the previous so I'm hopeful. Overall at this point I consider it a good and solid investment and the price is comparable with the others of similar specs.

TLDR: It works, but does not live up to claims, only recommended for small vehicles and if deeply discounted.The good:Light, compact, straightforward to use and comes with a nice hard carrying case with a strap that fits both the unit and it's accessories.Decently powerful flashlight built in.Can power small usb devices if needed.The disappointing:I am not an expert and don't have professional diagnostic hardware, but from my tests with charging it from an ecoflow battery of known capacity (and measured power flow) and then using it to charge my phone, also with a known battery capacity, I feel like this thing only has about 2/3-3/4 at best of what's expected. I have a light 4cylinder engine and from my test results I also have serious doubts about how well it can start anything as large as a pickup or SUV, especially if in cold weather and it does not go on the first try.There is no fast charging in or out, this along with the fairly small battery capacity makes it a poor choice as a power bank.Seems to be bleeding about 1% charge per 3-4 days just sitting in my garage, not sure if this is intended or normal, but seems a bit excessive. Will certainly need regular top-ups if this continues.Also not sure if this is normal or not, but I noticed that it seems to be a bit unstable when charging even before reaching 90% capacity: while something like my phone would consistently pull 15 from the ecoflow when charging, the power draw on this thing keeps jumping between 9-14 with the screen dimming a bit when it does so. Not sure if this is a lipo vs lithium ion thing, or just how the battery management on this thing works normally, but thought id mention it just in case.
