Duracell Powersource 660 Watt Hour battery (12V, 55Ah) $299.97

This is more of a UPS product than a portable power station.

This thing uses a lead-acid battery so it's huge and weighs a ton compared to lithium power stations (ie: 26kg vs 6kg Jackery) . Also, deep cycling lead acid batteries greatly shortens their lifespan. Another disappointment is that it is not pure sine wave.

not a bad deal for wattage... however it's way too heavy. 26KG is something you don't want to carry around...ever

Thank you for the informative response. Is there any benefit to lead acid?

Advantages
Inexpensive and simple to manufacture.
Mature, reliable and well-understood technology - when used correctly, lead-acid is durable and provides dependable service.
The self-discharge is among the lowest of rechargeable battery systems.
Capable of high discharge rates.


according to https://batteryuniversity.com/

LFP would be better.

If it's anything like there alkaline batteries, this will leak in no time.

There is no advantage to Lead Acid batteries except you can recharge them below freezing temperature. This is the only reason we still lug them around in cars. We could use smaller car batteries and combine them with supercapacitors. If you start your car often (daily) then you can just use supercapacitors instead of a LA car battery. After 2-3 days and they go dead. Supercaps will outlive your car, so no more battery maintenance or cleaning terminals, and fuel savings from the weight.
You cannot discharge LA all the way or they are destroyed, you only need a small lithium battery to get the same amount of power. Lead acid have the shortest lifespan of the battery types.
By the amount of power you can put in and take out over its lifetime, LA is more expensive than lithium. LFP batteries can go 10 years and still be useful.
LA is for poor ppl who cannot invest in a better battery or only want it for a very short term. Or for ppl who do not know any better and keep replacing it every 3 yrs or so. Maybe if the prices of better battery tech have inflated more than the old ones it would make the old tech compete but it is still a dinosaur.

So a 600ah, 1440w modified sine wave inverter with UPS functionality for 300$. I mean not bad, the external terminals to extend the ah of the unit makes it convenient and cheap to expand. The manual is very light on details but since it has UPS functionality it would in theory support pass-through charging, Have no idea if it will also charge the externally connected battery either.

Was going to order, but it's just too heavy, and as stated above, not perfectly suited for a UPS.

For anyone that has the need for this, it's a great deal!

Yeah a 12V SLA AGM 55AH is already $200+

The battery is worth about $230 to replace. and will last at least 3 years. Consider changing to lithium and save some weight next time

My studio reference series subwoofer weighs 92lbs so this being 58lbs is still being able to lift but not for someone who has a weak back. Would be curious as to how long it would last on a full charge.

Well, it completely depends on what you plug into it. You can estimate looking at the specs on your device(s) and some math.

684 Watt Hour Kirkland car battery is $160+tax. considering that this unit is hardly portable, it seems like you are better off getting that and then buying some high quality components. I am sure this is useful for some, but just to put things in perspective.

I ordered this to give it a try to power my garage fridge/freezer/router during an outage.

I have been looking at other units sold by Jackery etc for 3-4x the cost. Since I won't be moving this, I don't have an issue with the size. I also like that I can daisy chain additional batteries to extend the use. I won't be using the solar charging but it's nice that it has that function.

With the Costco return policy, this is worth a try, even if it's not pure sinewave - I don't think the garage fridge will care (but ya never know!).

Modified wave no thanks

absorbed glass matt batteries can withstand deep cycling much more than regular sla batteries. suggesting that this will be dead in 3 years is complete horseshit. i have an optima yellow top that’s 10+ years old and it works great.

lithium batteries can also explode when punctured.

If you look at Duracell's site they say 4-8 hours on a fridge but 10-12 hours to recharge. To me the uptime doesn't seem good enough even if I have a friend to take it to.

If its not lifepo4, its not worth it at this price

AC motors, like the one in the compressor in your fridge, are one of the things that do benefit from full sine. having said that, it will almost certainly still work. the compressor motor may be less efficient, get hotter, and (if used continuously) fail sooner, but for situations where it will be powering your fridge for a few hours in a power outage, i would not anticipate any problems.

i strongly recommend anyone who is considering a UPS, generator, or any other type of backup power, to purchase and use a kill-a-watt, or similar energy monitoring device to understand how much power your devices use. i was quite surprised to find that in the winter, my starlink dish uses almost 200w of power continuously (likely due to heating the dish). this is considerably more than, say, your fridge and caused me to reconsider the type of batteries i was going to use. (i have deep cycle SLA batteries, because they work with my existing charging system, and LiPo batteries are expensive)
