Quote from BudmanTom :
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?

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?

Can you list everything since you just finish building it. Everything including the box.

Around 960 if the battery could be drained that far.

If I did the calculation correct it's 13,100Wh compared to 250 for BigBlue.

Quote from Birdman84 :
$.16 seems really high around here MD mountains. $10 kwh
The other guy is right , it is about .16 kwh. I'm in florida it lists:
customer charge 11.40
energy charge 8.11c
fuel charge 2.81c
tax 5.17
So it would seem it's 10.91c kwh. But you have to add 11.40 customer charge to that and tax .... and it comes to about actual charge is .16kwh for me too.

Easy way to do it is take my utility bill for the month I used 303kWh.
my bill is 50.53 for the month.
So 50.53 divided by 303 equals 0.16c per kWh.

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.
You can try to study this product - https://www.amazon.com/gp/product...6YFO&psc=1 or move into "heavy duty" territory like https://www.bluetti.com/products/...er-station

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:

Quote from InfamousDX :
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.
it depends what your requirements are. B and J do have quick recharge (2-3 hours). J 300 and bigger models have simultaneous charge function (recharge 1.5-2h). Some B models support up to 60V input so you can put solar in series. Customer support speaks english and less likely to give you the runaround. If you have extra money go for it

AC output doesn't work while charging from Solar Panel

Battery Type: Original High Quality Lithium ion Batteries
Batteries 1 Lithium Polymer batteries required. (included)
Battery Cell Type Lithium-Cobalt

the seller can't figure out what kind of battery is used in it?
You seem not to realize that the three statements describe different aspects of the battery. Something like a vehicle, a car, a coupe.
LiPo is a kind of a Lithium-ion battery. These are Cobalt based rather than Lithium-Iron-Phosphate.

What is the chemistry of the battery? Clearly it is not LiFePO4

Its got 30 lithium coblalt oxide 18650 cells...

These are also referred to as "NMC" cells

Lower power density (2200-2300mah) more robust, cheaper.

Just got this the other day for occasional power outage. I just need it to be able to power our wifi router and recharge laptops and phones. It has LifePO4 battery. 96000mAh, 298Wh, 320W, includes type-C 60W PD, regulated voltage. I haven't tested it to see if it's any good. $200 when I bought it the other day after $60 off clickable coupon. Inside the box I found an offer for a $30 Amazon gift card if you leave a review (good or bad).

https://www.amazon.com/dp/B08GPL38M3/

Any opinions on this? Not sure if it's a good buy/keeper.
