A jump starter is an essential part of car's emergency kit.

They range wildly in quality and price, but the best and most expensive cordless jump starters feature a LiFePO4 battery instead of lithium-ion or lead acid.

During the Amazon Spring Sale going on right now, one such model - the Lokithor J150 Pro LiFePO4 Cordless Jump Starter - has dropped to $48.43 with free shipping after coupon code "V3GXQIUE".

You won't find any other LiFePO4 jump starter for under $50 on Amazon.

Lokithor gets away with the low pricing by lowering the amperage and battery capacity, but read on and you'll see that the compromises are well worth the battery tech upgrade.

Let's talk about the best feature about the Lokithor J150 Pro.

Unlike every other cordless jump starter in this price range, it has a lithium iron phosphate (LiFePO4) battery.

LiFePO4 batteries have safer chemistry; their thermal stability gives them a much smaller chance of catching on fire than a lithium-ion battery.

They will also retain more charge when left alone for long periods of time, and their total lifespan is longer than lithium batteries (usually at least 10 years).

Finally, if you're in cold weather country, LiFePO4 batteries operate at lower temperatures more efficiently than lithium-ion.

If you're worried about the "low" 1,350-amp rating, don't be.

A 1,000-amp jump starter is good enough for the vast majority of cars here in the US, which have anywhere between 1.6L and 3L gas engines.

This jump starter is perfectly fine for most trucks as well, unless maybe if you're rocking a souped up beast with a V8 or higher engine.

The 7,000mAh battery capacity means you can get by with several jump starts before needing a recharge, although I would still recommend keeping your battery topped up.

You can also use it as a battery backup for your smartphone in a pinch, thanks to its USB-C port with 30W of Power Delivery.

USB cables are also included.
