For battery backup?
I just bought this on Amazon after a lot of chatter w/
@telegraham and others, was on sale for $178.
Found
HERE
I have 1 smart plug into it and that controls 4 vital equipment. Return Chamber Pump, Heater, Kessil and Maxspect gyre pumps. Depending on the season I can pick what I want running.
FYI these battery power stations are kinda a hobby / collection of mine
The one posted is a decent amount of watt hours (256) for the cost ($178)
There are many in this price range that are 250-300 watt hours
Next big step up is 500+ watt hours and there is normally a huge price jump
I am happy I found this, BigBlue 537 watt hour unit for $250 (it had a $50 coupon when I bought it so keep an eye out) currently $300 no coupon
Bigger battery = more run time but also = more time to charge. This one doesn’t take those 40-60w laptop style power adapters, it has a built in 300 watt charger and takes a normal IEC power cord. It will charge to 80% in about 90 minutes and no power brick to lose
Let’s say your gears load is 75 watts total
With the first one:
(256x.8) / 75w = 2.73 hours runtime
Second one
(537.5 x .8) / 75w = 5.73 hours
I use these on dc return pumps only during outages. I have several different ones. My 75g reef return pump is 20 watts (I reduce to 30% for outages to save power) and that will last me 21.5 hours.
If anyone is looking for a battery power station for roughly $120 more (no coupon) or 75$ more when the coupon is there, you can get over double the run time, and charge in 4x less time
The coupon comes and goes every few weeks
