Prime Day 2020 car accessory deals: Dash cams, chargers and more

The NOCO GeniusBoost Plus GB40 offers 1,000 amps of cranking power for under $100. That's not bad for something that claims to be able to crank over up to a 6-liter gasoline engine or a 3-liter diesel. Now, thanks to Prime Day, this thing is only going to set you back $69.

Next up on the NOCO food chain is the GB50. This little powerhouse offers up 1,500 amps of cranking power which NOCO claims is enough for a 7-liter gas engine or a 4-liter diesel. The GB50 is usually $150 but during Prime Day it's knocked down to just $104.

The next step up is the GB70 -- the model that we feel is the sweet spot in the Genius Boost Plus range -- which offers 2,000 cranking amps. NOCO claims this will spin over an 8-liter gasoline engine or a 6-liter diesel. More accurately, this thing will crank your normal passenger car over regardless of how cold it is, and it'll do it for longer. Normally the GB70 retails for $200, but now you can get it for $126 which is a stellar deal, no matter how you slice it.

If you find yourself regularly needing to start boats or construction equipment or ultra-high-compression racing engines -- or you just like overkill -- then you should look at the GB150. This little monster will output 4,000 cranking amps which should be good enough to spin over a 10-liter-plus gasoline engine or a 10-liter diesel. It's on sale now for $210, well down from its usual $300 asking price.

Tires are arguably the least sexy parts of a car. They're big, black rubber donuts but for those of us in the know, we know that those donuts have the biggest impact on how your car performs and how safe it is, because they're the only part of the car actually touching the road. A big part of helping tires perform at their peak and last as long as possible is keeping them properly inflated. Doing that involves knowing what pressure they're at initially and unfortunately, that requires some specialist equipment -- aka a tire pressure gauge. The little pencil-style ones you get at a gas station are terrible and inaccurate, you're better than that. Pick up this digital gauge from JACO and always be at the right pressure.

Being able to help yourself out of an automotive jam is an important part of being a grownup. Relying on the kindness of others will only get you so far, and it always sucks to have to call AAA just because you have a flat tire. Now, for less than $50 you can be the master of your own destiny and pump up your own tires with the Avid Power Tire Inflator Air Compressor. Yeah, it looks like a drill, but that's cool. This is also awesome if you're a frequent off-roader and find yourself having to air-down regularly.

If you're interested in owning a vehicle diagnostic scan tool so you no longer have to pay someone else to diagnose your vehicle or reset your check engine light, but you also don't need or want anything so fancy as a Bluetooth dongle, the Foxwell NT301 is perfect for you. It's under $70, has a color screen and provides a ton of easy-to-read information about your vehicle's health.

It used to be that if you had a check engine light or if maybe your car was just running poorly, you'd have to either shell out a boatload of greenbacks to a mechanic to scan your car's OBD2 system, or you could spend a bunch of money to buy your own but it would be this cheap-looking plastic thing with a crappy screen. Now, we're living in the future, so you can have all the functionality of those dedicated devices on your phone. That's why the BlueDriver tool is so cool. The dongle plugs into your car, and connects to your phone where you have access to tons of scan tool functionality plus real time monitoring of some important vehicle functions -- but the best part is that it's less than $100.

With 1080p recording, a wide 170-degree capture angle and an impact-sensing accelerometer, the Apeman Mini boasts almost everything you need to start automatically capturing footage on the road -- you will need to supply your own SD card, but that's often the case. The unit's 2.0-inch screen is tiny, but also low-distraction. You'll almost forget it's there until you need it.

The Campark Mirror Dash Cam integrates its forward-facing 1080p dashboard camera into a large mirror display that clips onto your car's existing rearview mirror. Meanwhile, a second 1080p camera at the rear of the car serves as a second DVR and as a backup camera when reversing. The installation is a little more involved than the average dash cam, but if your car lacks a rearview camera, this is totally worth the effort and the additional cost.
