Yes, Jackery has good marketing and does seem to be the best as in quality of construction "robust", but as the kid in the video points out it is not necessarily the best in terms of performance and some of the cheaper options, perform better. The Jackery is far more expensive. Does it make sense to buy two cheap version vs. one Jakery? These are also smaller portable versions, do things change when you get into something a little larger say 1000amp hour units? Regardless it doesn't seem one unit does it all?
I am beginning to think you need multiple units, redundancy like an airplane. This gives you back if one goes down and a unit to use while one is charging or being repaired. Also more designated units? Such as a jump stat box, phone chargers and then the main unit such as a jackery or one of the others?
Rule of thump seems to be $1.00 per watt hour. So rather than buy one 1000wh unit for $1,000.00 can you combine multiple units that create redundancy for the same money and perform multiple tasks?
a main unit such as the Expert Power unit in the video recommended by the kid? 300wh, $250.00
Then maybe a jump box $70.00.
and maybe a few power bricks to recharge small electronics? $25.00 each.
