Question 1

How long will it power a C-Pap?

Accepted Answer

I use a CPAP but I do not use a heater or humidifier (both of which  use much more power than just the CPAP) and I normally sleep about 7 hours per night.  In an overnight test, it used only 11% of the full charge.  As another reviewer stated, under these conditions, it should last at least a week without a recharge.  You will also get more life out of a charge if you have a 12v adapter for your CPAP.  Otherwise, you will lose about 10% in the conversion from AC to DC.

Question 2

Is the battery chemistry lifepo4?  what is the maximum recharge rate allowed?

Accepted Answer

Short answer: No. All of the Jackery units use Lithium Ion NMC (Nickel, Manganese, Cobalt) cells. The max recharge rate for the Explorer 500 is 100 watts. If you want a LiFePO4 unit, check out the Bluetti EB70 for $599 on Amazon.

The Explorer 500 is made up of 48 individual Lithium Ion NMC cells (18650's) soldered and sealed inside the unit. There are groups of 8 cells in parallel, and 6 of these rows in series. Each cell has a battery capacity of 3,000 mAh (milliamp hours) @ 3.6V (nominal cell voltage); or 10.8 Wh (watt hours). Basically 3.0 Ah (amp hours) * 3.6V * 48 cells = 518.4 Wh of total battery capacity.

The battery you are asking about is called Lithium Iron Phosphate (LiFePO4). It has many advantages over Lithium Ion; including longevity (2,500 cycles and/or 10+ years), and overall safety. The one big disadvantage is that it weighs significantly more the Lithium Ion, or Lithium Polymer (LiPo); though not nearly as much as lead acid.

If you want a LiFePO4 unit, check out the Bluetti EB70 for $599 on Amazon. It has a battery capacity of 716 Wh (watt hours); and an AC inverter max rate of 700 watts. Though is does weighs 21.6 lbs.; as opposed to only 13 lbs. for the Explorer 500. Hope all this helps. :)

Question 3

Will this support my 12volt 50 watt compressor fridge?

Accepted Answer

In theory it will run it for 10 hours. In reality the fridge will cycle and you'll probably get about 3X that much time. (assume the fridge is in the shade and about 80 degrees)
Most fridges will run about 30% of the time. If you put in in an insulated bag (if available for your model) you'll get more efficiency.
You can also throw a beach towel over it. (just don't block the vests) you'd be surprised how much that helps.

I gave this a much longer review but Amazon has not published it yet. But look for a review from my name where I touch on using this for a fridge.

Question 4

Anyone done a side-by-side comparison of the Jackery 500 with the Suoaki 500?

Accepted Answer

FYI:  According to the Amazon listing the Suoaki 500 takes 7-8 hours to charge with their 100w solar panel...The Amazon listing for the Jackery states it takes 9.5 hours to charge with their 100w solar panel...So the Suoaki only charges 25% faster than the Jackery, not double or 100% faster that another reviewer had mentioned...So either take the 500 watt, or 65% more output inverter on the Jackery or 25% more charging speed of the Suoaki...
