Exactly! It is all about this working - in one case that you can easily carry around. Now, I have an EcoFlow Delta 1300 so I think this is a little small and as you know, won't operate anything significant for long.

That one weighs a bit too much for me to try to go mobile with it and it's overkill for anything I'd out of the house. I have the ecoflow r600 pro with the pro kit that allows me to connect other batteries with it.

Hopefully it works for you and your needs. Most people only use these batteries for phones, drones or similar devices. Maybe a laptop for a little longer outing. This one works great for that. My R600 pro makes my miter saw mobile. Just rolled it around to the backyard and plug it in. No need to deal with any long cords.

This is the real trick!

Can a 300W inverter like this one:

https://www.mercari.com/us/item/m20100572029

Its $74, and now you're done ASSUMING you have a bunch of 60V greenworks batteries. I already have 2 from my lawnmower and trimmer. Those things are a beast, like the lawnmower is a 4aH battery, so thats 240wH! That'll keep even a 40W small PC running for 4 hours! Or let you recharge your phone 20 times. Also, more likely to already be fully charged before a blackout....

Repped! I had no idea these existed! I only have DeWalt flex volt... Will that fit or is there one that will? Did some quick searches for dewalt specific options and came up empty handed.

I only found this beast (actually a good deal considering the amount of batteries AmH it comes with):

Hopefully some cheaper/simpler options exist but I'm too poor to afford Dewalt stuff....

What product do you use for your CPAP and do you have a link or suggestion?

I use an aimtom 155Wh "solar generator" with a TP-solar 60W array. For powering the cpap I bought a dc to dc car adapter
battery: https://www.amazon.com/gp/product...UTF8&psc=1
solar array: https://www.amazon.com/gp/product...UTF8&psc=1
cpap adapter (specific for dreamstation): https://www.amazon.com/gp/product...UTF8&psc=1

This setup works well for me, to maximize uses without charging I turn off heating on my cpap. OPs product is more power for not much more money so I would have probably gone with it if it was available at that price when I bought my setup.

Are there any battery powered kits out there that would run an AC sump pump in a power outage?
Even if it is just for 30 minutes a day. Just long enough to keep the basement from flooding.

No. Depending on the sump pump you probably need between 1200w and 4000w to start it. You won't be getting that out of anything battery powered. They have battery powered backup pumps. They aren't very powerful, but if you can get by with 30 minutes a day they should be fine.

this thing carries around $.04 worth of electricity.

1kwh from mommy power company typically costs are $.16

meaningless for sure, I just found it amusing.

What's that in peak Texas rates? 10k?

I want one of these portable power stations that can charge my motorcycle battery using the SAE adapter. I bought one from RavPower "Portable Power Station RAVPower 252.7Wh/70200mAh Solar Generator" and left it to charge the battery overnight. Did not work. Anyone knows if there is a portable powerstation that will charge a motorcycle battery?? The one i got before is:

Holy hell that's a tank. I hope something cheaper exists. I'll keep looking.

I'm a DeWalt noob, and only bc of the sales they've been running lately.

*Shakes fist at SD gods*

Stoked to be getting away from fuel powered tools though!

You are right.

Actually, there are no such thing as generator. Even your conventional gas generator doesn't generate energy. It is just converting stored chemical energy from the petrol to a usable form like electricity. That's the law of conservation of energy . https://en.wikipedia.org/wiki/Con..._of_energy [wikipedia.org]

Now add a solar panel to this listed product and you will also be able to convert the sun rays to a useable electricity. The good thing is, you will also be able to store that energy from the sun in to this product and use it when it is needed.

Again, there's no such thing as a generator. You cannot generate energy. You can only convert it to one form to another.

I dunno man, there is a lot of BS being generated in this forum. LOL

Do you think the Bluettis and Jackerys of the world are worth the premium vs. these no name chinese brands? I have both and am starting to lean towards the cheaper brands.

There can actually be variation in cell quality as well and electronics quality. For instance, you can have a setup where the protection circuitry draws quite a bit more than a good brand, simply due to poor design and have a system that self discharges the battery pretty quickly.

Poor cell quality or charging circuit quality could lead to cell mismatch in a shorter amount of time than expected, often if you lose a cell, you lose the whole battery pack. If the designer didn't include cell balancing for instance, coupled with cheap unmatched cells, this becomes a more prominent potential issue.

Generally I am all for cheap electronics. If they work, they often keep working. But, it becomes a little more hairy with batteries. When you add in long periods of time for sitting on the shelf, it increases the chances you will pull it out and it will be unexpectedly dead when you need it.

Pick the smaller of the two. I would not recommend going that route. I was only using it as an example.

Thank you so much!

While "BigBlue" is great and it certainly serves a purpose if you really wanted some reserve power wouldn't it be better to get something like a deep cycle battery and a power inverter?

https://www.walmart.com/ip/EverSt.../164242687

https://www.amazon.com/Kinverch-C...NrPXRydWU=

I'd like to have a good backup for my Cpap and "BigBlue" should do the trick but for less money I think you could do better?

How many Wh would that set up produce?
