Jumper cables? Nah....there is a newer better solution.

I read on Mopar Action awhile back about these new battery jumper boxes:

These are interesting. I like the idea of having something lightweight and compact to bring with any vehicle I'm taking on road trips. No need for getting help from someone else for a jump start if you accidently leave the lights on or some other mistake. Some of these come with built in lights or air compressors. Some will allow recharging of a phone, camera or other low demand accessories.
If you have one, do you have a recommendation for a brand or model that you liked?

I have good electrical and charging systems in my old stuff but having something like this may be a smart thing to consider.

The top and bottom ones look like they are dry cell (Like Lith-ion, etc) with the pros and cons that come with them.
They certainly can work. I think their longevity and safety depend heavily on the quality of the electronics.

The middle one looks like a traditional boost box with a lead acid cell. You can get 'em with inverters built in, and in theory the battery can be replaced. I have an inverter one on the shelf with a battery replacement in my 'roundtoit' file for 10 years.
