Need a new portable battery ala Microstart XP3

[MacDoc]

My Microstart Xp3 has been wonderful travelling and starting a few vehicles but it is expanding now in its case so don't trust it anymore for safety. Also love the flashlight and use it for the phone all the time. Certainly got value for money - 4 years or more all over the world.

I like their technology .....I suspect it's better now. Any other brands to consider.??

.. I may want something a bit bigger to charge my laptop in a pinch USB-C might make it easier.

Certainly will stick with name brands tho. Suggestions>?

update ...looks like the XP-3 now offers a USB-C adapter and my existing adapters likely work.

Made me laugh this review

My favorite story is when my wife was at a fruit stand and a trucker walked up and asked the proprietor if he had jumper cables as his diesel dump truck had gone dead across the road. The trucker laughed at her when she pulled this little jumper out of her car, but he stopped laughing and started writing model numbers down after she connected it and he fired the truck up!
