I just picked up the EcoFlow River Pro portable power solution with extra battery from Costco for $699. Normally the basic unit sells for $500 and the extra battery is $400. The Costco deal running through Oct 24 gives you the extra battery for just $200 (half off). While the extra battery doesn't give you more wattage output, it does double the run time. The basic unit is about 16 pounds and so is the battery. So, if I don't need a long run time, I am not carrying the extra 16 pounds.

My main purpose for this is to run my CPAP when camping (and of course emergencies). It is replacing my 80 lb deep-cycle marine battery and separate 600W inverter I used to take. That was overkill but since I already had it, I used it. It is truly a pain to move around though. We usually go camping in large groups and everyone seems to want to charge their phones with my setup. This is where that spare battery will come in handy. My next camping trip is in a few weeks.

I also picked up a 100W folding solar panel to with it off of Amazon. I really would have preferred 160 watts or more but those units are much less portable. This guy folds down to about the size of a ream of paper. It comes with a carrying case that holds all the accessories and stands too.

I used it yesterday to power my pellet grill (Traeger). While the grill is heating, it was pulling about 240 watts. The unit said it had 9 hours of run time at that discharge rate. After a few minutes, the heating element of the grill turns off and only the fan and auger are in use. This brings the power draw down to about 75 watts (about what many PC laptop power supplies take). The unit reported it could go 21 hours at this draw level.

I am actually pretty pleased with the readout on the unit. It shows you the actual power draw in watts and gives you the remaining life indication. The display also shows you how fast the batteries are charging and how long it will be before fully charged. The maximum charge rate was about 670 watts. Once the battery reaches 95% capacity, the charging gradually slows down to a trickle (50 watts) just before it hits 100%. I found the remaining charge time indication to be a bit pessimistic. It charged considerably faster than the indicated time. At one point near capacity, the remaining time readout just dropped by about 10 minutes. The manufacturer claims it can do an 80% charge in 1 hour when plugged into an AC source. Charging it from a solar panel or car battery would take a lot longer as the max charge rate would be 100-200 watts.
