most (especially the big brand names such as Bluetti, EcoFlow) do NOT have Anderson plug outputs and these are useful as:
more reliable than cig lighter whilst traveling on corrugated roads - your cable wont disconnect and your food in the fridge won't need to be thrown out
allow up to 50A DC current per plug which allows more versatility to use multiple DC devices instead of relying on 240V AC devices which will use up your battery very quickly and are much less safe than 12V devices for camping - 240V will kill you, 12V won't!
the 12V cig lighter only allows 10A or 125W, whereas the Anderson plug will allow 5 x that much
iTechWorld PS2000 has an XT60 DC output which allows up to 25A and you can buy a cable to convert this to Anderson so this is a reasonable compromise
they are heavier than a similar capacity 12V battery and battery box as you have to carry the other inbuilt components
many have a proprietary solar input and maybe restricted to max. 200W solar panels
many have very slow charge rates of only 10A and do not give you the option of upgrading to a faster charger - the better ones allow full recharge on AC within 2-3 hours
they may not allow charging from your car's alternator, and if they do it may be at a slow rate via the cigarette lighter plug which is limited to 10A
the included AC inverter is ften a low wattage which limits its use (a 2000W one would drain your battery much faster but is much more versatile)
now that laptops and the latest cameras can be charged or run by USB-C, most people don't really need AC power unless they want to use induction stoves, hair dryers, etc.
if one component breaks, you may need to get a whole new power station if it can't be repaired
they are a very attractive target for thieves
