Energy (Wh): The total energy that can be stored in a unit, measured in watt-hours (Wh), indicates how much juice a unit can ultimately output. The higher the number the more jump starts a unit will be able to do before needing a recharge.
These were his words, “really, this is an awesome product. It’s compact and has a lot of power. And easy to use.” He then asked, “can I keep this one?” You know I don’t say “no” to my friends…

Given the BUTURE Car Jump Starter's performance and feature set, its price point is another delightful surprise. At roughly half the cost of well-known brands, this device offers exceptional value for money, particularly considering its utility in emergencies. I think the 7L claims are a bit too high. After 4 jump-start tests, the battery came down to less than 50% from a full charge. It can provide around 6ish jump-starts when fully charged. At the heart of the BUTURE Super Capacitor Jump Starter lies its advanced super capacitor technology. Unlike traditional battery-based jump starters, this innovative device utilizes super capacitors to store and discharge electrical energy efficiently. In the next week, all the jump starters arrived. I unboxed them and put them on charge. Some jump starters came with a little bit of charge, like the ones from Noco, RuggedGeek, Nexpow, and Clore Automotive, but I still topped these all off.
You should never spend your money on any product or feature that you are never going to use or take full advantage of. This is no different when it comes to jump starters. This is why I tested all the jump starters by completely disconnecting the vehicle’s battery (which was a known good battery) so the only thing starting the vehicle was the jump starter itself. The USB-C port on the jump starter delivers power according to the PD standards and can charge your USB-C devices like modern laptops or smartphones at the fastest possible speeds. For me, reverse polarity doesn’t matter, because I am good with cars so I know what I am doing, even if I am in my sleep. In my testing, I found that this jump starter finished charging in 2 hours and 33 minutes when using the included charger.User Manual: A detailed user manual is included to guide you through the setup, operation, and safety instructions of the jump starter. Locate the positive (+) and negative (-) terminals on your vehicle's battery. Connect the corresponding jumper cables from the BUTURE Super Capacitor Jump Starter to the battery terminals, making sure the connections are secure.
This jump starter is built solid and has a nice weight to it. 4 LEDs indicate the remaining charge on the jump starter. Clamps on this unit are made from plastic. In my testing, the clamps proved to be stronger than I expected. In my real-world testing (on a vehicle with a weak battery), this jump starter was able to jump-start a 4.6L V8 gasoline engine just fine. I also tested this jump-started with a bigger 5.7L gasoline engine, and it took a couple of tries but fired right up. Safety has not been overlooked in this design. With high-quality cells, advanced circuitry and upgraded safety features, this jump starter promises protection against surges and short circuits. Peak amps don’t matter. Always look for cranking amps (CA) or cold cranking amps (CCA) if you live in a colder climate. I then punched these readings into a spreadsheet and exported an easy-to-read chart that you can see below: This is the average of peak amps delivered through my jump start tests.All the big, less-portable jump starters have compressors built into them. I found that Clore Automotive performed better than all others and provided more consistent results than any other air compressor-jump starter combos. Safety is a top priority, and the BUTURE Super Capacitor Jump Starter delivers on that front as well. Its battery-free design eliminates the risk of heat, rupture, or explosion due to pre-charging. With its long lifespan of at least 10 years, you can rely on this jump starter for years to come. Table of contents
