In Depth Review of the autowit SuperCap 2 Portable Jump Starter

There are few things more frustrating than a dead car battery. You count on your car to work when it’s time to go. Whether you’re going to work, the grocery store, or a friend’s house, that dead battery can really ruin your day. Instead of going about your business, you’re now trying to fix your battery. One easy way to get back on the road is to keep a set of jumper cables handy. But jumper cables are only part of the equation. You still need some kind of power supply. In most cases, that means you’re counting on a friendly stranger to help you out.

The alternative is to carry a portable jump starter or power bank. This way, you’ve got everything you need to get your car started back up. Even if you’re stranded in the middle of nowhere, you don’t have to wait around for a stranger. Of course, some of these tools are worth using, and others are less worthwhile. Thankfully, we’re here to help you figure out which ones are worth your time and money.

Today, we’ll be looking at the autowit SuperCap 2 Portable Jump Starter. This is an ultra-compact, capacitor-based jump starter. Because it doesn’t have a built-in battery, it doesn’t require constant recharging and maintenance. It also doesn’t come with most of the safety concerns that are attendant to batteries. But does this mean you should run out and buy one? Let’s take a closer look, and see what else it can do for you!

Design & Construction

TheAutoWit SuperCap 2Portable Jump Starter是您的汽车或卡车的超紧凑型充电器。它仅尺寸为10.43英寸，宽4.52英寸，厚1.77英寸。您可以将其存放在杂物箱，床盒中，甚至在插孔旁边。它的体重仅为2.34磅，也很轻巧，因此您不必为此而苦苦挣扎。这种紧凑的设计是一个重大好处，使SuperCap 2在比赛中脱颖而出。大多数汽车的起动器相当笨重，这使它们变得很痛苦。

All of this is possible because the SuperCap 2 utilizes a capacitor system instead of an internal battery. This capacitor is exceptionally lightweight, compared to the several pounds that a comparable battery would weigh. In addition, capacitors are safer than batteries. Whereas batteries can swell, crack, or explode due to heat, capacitors will be just fine. In other words, you don’t have to worry about leaving your car parked in the sun in summertime. Your capacitor isn’t going to get damaged because it overheated.

The case itself is constructed from injection-molded plastic, with rubbery padding on both sides. The case is black in color, and has a satin finish that’s easy to keep clean. The padding is orange, providing high visibility so the charger is easy to find in the dark. Towards the top, there’s a small LCD display that provides basic information. When the SuperCap 2 is activated, you’ll see the voltage as well as the total charge percentage.

在设备的一个角落，您会发现一个覆盖输入和输出的橡胶塞。有一个微型USB输入，一个12伏DC输入和套头衫电缆的输出。还有一个简单的电源按钮来激活电容器。该套件包括一台12伏电缆，用于汽车的香烟插座，以及用于跳跃的鳄鱼夹。还有一个方便的携带箱。它是黑色塑料，带有电容器，电缆和手册的空间。这使SuperCap 2方便存放，无论您驾驶哪种汽车。

The entire kit comes covered by autowit’s 1-year warranty. In general, electronics will either fail early on or not at all, so this should be more than good enough. If your capacitor is still working after a year, chances are that it will last for a decade or more.

如何使用

因此,电容器充电机是如何工作的不同ently than a battery-powered charger? To understand, it helps if you first understand how electricity works. Instead of electricity flowing through a wire, imagine water flowing through a pipe. The water pressure would be analogous to voltage. The volume of water would be analogous to amperage (amps). The combination of those two factors, the total power, would be analogous to watts. To start a car engine, you don’t need terribly high voltage. 12 volts is more than enough, in theory. But you do need a lot of amps.

The theory behind a capacitor jump starter is simple. When your car battery dies, it almost never runs completely down to zero. Usually, there’s still some charge, just not enough to start your engine. Again, think of our water pipe example. There’s still some water moving through the pipe, but there’s not very much of it. A capacitor gathers up that trickle charge over the course of a few minutes. Then, when it’s activated, it releases a rush of high-amperage power that starts your engine. Once your engine is going, your car’s alternator will recharge your car battery.

有三种不同的方法来收集所需的力量。首先是简单地使用汽车电池上的联系人。这通常是最简单的方法，因为无论如何您都会在引擎盖下，大约需要3分钟。另外，您可以从汽车打火机上汲取电源，大约需要五分钟。如果您的电池完全死亡，那么您仍然没有任何选择。您可以使用USB电源库，也可以从另一辆汽车的电池中为电容器充电。这通常不需要。但是，很高兴知道如果您的电池完全排干，可以使用备用选项。

Regardless of how you power up the capacitor, a buzzer will sound when your capacitor is fully charged. At that point, you’re ready to connect to your car’s battery. Press the power button, and a 10-second countdown will start. This gives you enough time to get around to the front of your car and start your engine.

考虑到这一点，SuperCap 2只是一个充电器。它不能用作电力库，也没有其他内置小工具。如果您习惯于现代制造商包装成功能的产品，那么您可能会感到失望。但这只是电容器驱动设备的性质。没有内置的电池，没有意义上有手电筒或USB充电端口。

That said, there are plenty of other options if you prefer a more traditional power bank. For instance, theJumpi jumpstarteris a very popular option. Not only will it charge your car battery, but it also functions as a power bank and a vacuum. Another popular alternative is theTacklife KP200. The KP200 is similar to the Jumpi in that it also works as a power bank. But instead of a vacuum, it sports a built-in flashlight for roadside emergencies.

跳跃性能

SuperCAP 2的最大峰值电流为800安培。这足以启动道路上的任何车辆。在燃气车和卡车中，它可以启动到7.0升发动机，这对于任何消费车就足够了。在柴油车中，您可以启动最多4升的电动机。对于最大的卡车来说，这还不够，但是对于其他任何事情来说，这还绰绰有余。至于摩托车，船只，拖拉机和踏板车，您将拥有的果汁比所需的多。

The main limitation you’re going to deal with is the way the SuperCap 2 works. Because it releases a small amount of power in a high-amperage current, you don’t have long to start your engine. In all, you’ll have about a four or five second window, depending on how well the capacitor is changed. This means you have to follow the instructions carefully, and turn your key when the buzzer sounds. As long as you do that, you’ll be just fine. But if you’re not able to turn the key for some reason, you have to recharge the SuperCap.

In terms of environmental performance, you won’t have any concerns. The SuerCap 2 will work down to 40 degrees below zero. Unless you’re working the oil fields in Alaska, you’re never going to see anything that cold. At the high end the scale, it will work up to 158 degrees. Even if it’s been sitting in your car in a parking lot in summer, it will still work. The internal capacitor comes with a 10-year life expectancy. You’ll have a new car before you need to replace your jump starter.

Final Verdict

As you can see, theSuperCap 2brings a lot of value to the table. The most obvious benefit is just how small and portable it is. This makes it ideal even if you don’t have a lot of storage space. And let’s face it, even if you have a large vehicle, storage space is always at a premium. If you can keep your charger behind your seat instead of in the trunk, that’s more room for transport.

Of course, we should acknowledge the elephant in the room. The SuperCap 2’s capacitor-based design means that it’s only useful as a jump starter. It won’t charge your phone battery, and there are no extra built-in widgets. But if all you need is a jump starter, you’re looking at one of the more powerful options on the market. With 800 amps of peak current, the SuperCap 2 can start pretty much anything.

关于SuperCap 2，我们喜欢的另一件事是，有很多方法可以收费。理想情况下，您的汽车电池仍然会带来滴水。但是，即使不是这样，您也会有其他方法来为超级贴纸2充电2，总而言之，如果您只需要简单的跳跃启动器，就可以选择一个绝佳的选择。
