Factors to Consider for The Best Car Battery Jump Starter
A. Primary Use
What you intend to use the jump starter for will help determine the best jump starters for you. On the other hand, most car battery jump starters and battery chargers are a little flexible. However, some portable car jump starter choices are limited to do exactly what they are meant to do. Consider getting a portable car battery with an in-built AC inverter, also make sure that the battery pack has enough power and is well suited for your needs.
B. Starting Amps
The starting Amps is particularly important, especially if you primarily plan to use the portable battery for its original purpose: jump-starting car engines. For instance, a sizeable V8 engine, particularly with a diesel engine, would require at least 500 cold-cranking amps of current to do that.
If you need to do this, you'll have a harder time using a jump starter intended for a 4x4 cylinder. Manufacturers should rate their portable motorcycle jump starter and car starter batteries for the different kinds of engines, so make sure to read the fine print of the jump starter battery. Also, look for the starting or cranking amps, and don't worry too much about its peak amp figures.
C. Total Storing Capacity
This is usually measured in amp-hours or milliamp-hours (where 1,000 mAh equals 1 Ah. This matters especially if you plan to use the portable car battery charger and portable jump starter battery as your backup or mobile power source. A higher number of these means more electrical storage capacity. The typical portable batteries are rated at 5-22 amp-hours.
D. The Chemistry
Portable car batteries run the gamut, ranging from the sealed lead acid battery alternatives to an absorbent glass mat to a lithium jump battery starter and the most recently, ultracapacitors. The chemistry involved doesn't matter as much as the ultimate utility, size, weight, and cost. However, if you want something you can keep in the glove box, a sealed lead-acid battery booster might not be your best option.
E. The Features
All the possible options are important, but then again, the size and weight matter a lot. All the features compounded in one unit gets the jump starter much bulkier, with weight that will probably exceed 30 pounds. For some occasions, like camping trips, this may not matter much. In this case, you'd probably not want to carry one of the biggest portable car batteries around in a Mazda Miata, for instance.
Some manufacturers, including the Antigravity brand, offer separate accessories like a small, powerful air compressor that works well with their paperback-size lithium-polymer jump starter batteries, but this adds to the cost.
