I carefully researched portable power sources for our recent 2-week camping trip. I wanted the battery to be just powerful enough (to reduce the cost and weight) to power a CPAP machine for at least 9-10 hours, better for 2-3 nights for flexibility. I also wanted a solar panel (economically priced) to charge this battery over 1-2 days (plus capability to charge the battery from a car’s cigarette lighter socket from a 120V outlet). Plus I needed a female cigarette lighter socket (ideally that would come with the battery) to provide a DC out for a CPAP adapter to avoid DC to AC and back to DC transformation and energy waste). That’s a lot of requirements I had as a consumer. In retrospect, not a single battery met all these criteria! They are either too heavy and expensive, or not powerful enough, and the solar charging capability desires much more efficiency. But iMuto met the power capacity, price and female cigarette lighter socket criteria, except their (optional solar panel) only allowed to charge the battery by about 15%, maximum 20% in direct California sun in 10 hours. I think the solar panel needs to collect more power or technology is not yet ready. Now I will describe my experience with an iMuto battery I eventually purchased. First of all, an iMuto battery appears to identical to the battery sold by Poweradd (so the manufacturer must be a 3rd party), except iMuto markets an optional DC to AC power inverter (which comes on top of the battery) separately, and Poweradd bundles them together. The overall price is fairly similar. iMuto should have stated clearly in their Amazon product page title that this is the battery without an inverter (which is pictured!). It is easy to get confused. The transformer is nice to have, although is not needed if you are only going to use a DC power source (12V or USB ports). This battery performed very well on my camping trip. It showed an accurate charge remaining (in percent), can be recharged in about 5 hours from a car adapter (either using a supplied 12V DC adapter or with an optional power inverter which is plugged into the cigarette lighter). As I suggested above, an optional 36W solar panel (made by iMuto) disappointed, as it charged this battery ridiculously slow (a simiar job is completed 10-12 times faster when charging via a car’s adapter or120 V outlet). I understand that a solar charge is much slower, but the panel should powerful enough to realistically charge this cube in just 1 or 2 sunny days at most. Most importantly, this 185 W-h battery powered my CPAP machine for up to 18 hours with a ResMed cigarette lighter DC to DC transformer (CPAP pressure 14.5, heater turned off). That’s pretty good. That’s I think is twice as better as the more expensive Freedom battery sold for certain ResMed CPAP devices. With this power source we also charged small electronic devices, when needed, and used its powerful LED lights (which should last for 24 h). But we got it for use with CPAP while camping, and it was a good choice. I had a chance to compare iMuto cube with the more expensive Monerator Gusto 10 Kit (which includes a solar panel, but can’t be charged from a car’s adapter without an optional 12V DC to 120V AC inverter). I was interested in a Gusto 10 as it is using a better, LiFePo4, battery (a 20-year newer technology), which can recharged bout 2,000 times as opposed to 500 times for conventional lithium batteries (technology of 1970’s) used in most other portable batteries on the market. But my Gusto 10 battery (despite stated 128 W-h capacity or maximum 80W power) didn’t last as long as iMuto/Poweradd cube (CPAP worked for less than 6 hours) and appeared to have inaccurate battery charge status after the 1st cycle. I retuned Gusto 10, and I am very satisfied with my iMuto cube. I am also keeping their solar panel (would give it a 3 out of 5 though) as it is folds small and costs just over $100. It might be handy for charging a phone and other low power devices directly. One of iMuto’s marketing tricks for their optional solar panel (compared, say, to Poweradd’s 40W solar panel) is that it is unfolded in such a size and shape, so it can be attached on your backpack to charge small devices when hiking. It is a neat idea, but it only works when the sun shines in your back! If you plan to use this battery with an iMuto cube (it would take 5-7 days to fully charge it from my estimate), buy an optional extension cable, as the supplied one is just a foot long.
In conclusion, I would highly recommend iMuto (or Poweradd) cube for devices which require a moderate DC or AC power source (like CPAP machines, phones, tablets, laptop computers - my iMuto cube came with a set of adaptor tips for laptops). It can also be used as a strong lighting source. An optional DC to AC inverter top (which should not really be sold separately in practical sense) is needed for devices which require 120V AC voltage, and this inverter also included a cigarette lighter female socket for power out. Poweradd overlooked this opportunity for a cigarette lighter out when selling their (identical) battery. I was unable to locate this exact socket adapter for sale elsewhere (most of these come with a different tip specification). I would NOT recommend the 36W solar panel sold by iMuto for charging an iMuto battery, but their solar panel may still be helpful if sun is the only power source available. I also looked at the 40W solar panel by Poweradd (no longer offered at the time of this review). It was nearly 50% more expensive, had less optimal shape when unfolded, and, importantly, the seller didn’t respond if any special adapter is needed to charge their power cube (but iMuto provided enough details in the description to know their panel should be fully compatible). As for weaknesses of this iMuto battery I would only mention these minor shortcomings. 1) The blue LED light on the optional power inverter top is way too bright for night vision (when used, e.g. in a tent). I had to tape it with multiple layers of a masking tape. 2) The battery can only be recharged 500 times, so it will last only 2 years if used daily. If you store it long term (>1 month), I believe these lithium batteries are best stored at ~40% capacity and recharged once every 6 months to minimize memory related issues.

* Q6: What kind of battery does use it? Can be used in Hurricane or Harsh Weather?
Sure, that'why we designed by lithium-ion for this portable power station, perfect to go camping in winter or Christmas Outdoor Yard decors.
A: The lithium battery (nickel salt, cobalt salt, manganese salt), compared with lithium iron phosphate (LFP) battery, it has the following advantages:
1. The energy density is 1.7 times that of iron lithium, which means the energy of the ternary lithium battery will be larger than that of lithium iron phosphate for the same weight of battery;
2. It can be used in a low temperature environment (minus 20 degrees Celsius / minus 68 degrees Fahrenheit can release 70% of the energy);
3. The charging constant current is 5 times that of lithium iron (20 degrees Celsius/minus 68 degrees Fahrenheit theoretical value);
4. The Cycle life is about 500-1000 times.
The LFP battery is the opposite, which is why we use it. So please don't worry about that. Operating Temperature: 14-104°F (-10-40℃), Recharging Temperature: 32-104°F (0~40°C)

Resmed Airsense 10 CPAP test results and why this battery is my best option.
I’ve wanted a battery solution for my Resmed Airsense 10 CPAP so I could take my grandsons camping for a couple of years. A few weeks ago a power outage made this a priority as I felt like I was suffocating all night. So I started doing research and bought this Imuto battery and the 24V converter for the Resmed Airsense 10 and S9 found at https://www.amazon.com/gp/product/B00UW34KR4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. I think Resmed is the only 24V CPAP so, if you have an Airsense 10, you need this to convert the power from 12V.Before I give you my results, another reviewer said “There’s a little trick to getting this to work, bla, bla, bla. But never said what the trick was. Well, here’s the trick. If you plug it all together and turn on the battery, it won’t work. The one way I found that the Resmed would recognize it had power was to connect the connection I’m pointing to in the picture, last, after turning on the battery. It’s the connection where the CPAP specific cable connects to the converter.My results....I turned off the humidifier, the heated hose and put the unit in airplane mode so it wasn’t searching for a cell signal.With the battery fully charged, after 8 hours of sleep the first night, the battery had dropped to 76%. After the second night of 8 hours of sleep, the battery had dropped to 42%. I’m sure I could have gotten a 3rd night but wanted my humidifier back by that point. So, I fully charged the battery and turned the humidifier to a setting of 4 (range from 0-8 I usually have it at 6). The battery lasted about 6 1/2 hours. I probably could have got more if I had preheated the water. The little converter was working like crazy until the water came up to temperature.If you use an inverter to change the power from 12V DC to 110 AC and then plug your CPAP into that which converts it back to DC, you will use (waste) most of your electricity in the conversion process. If you use a 12V CPAP with something like a cigarette lighter connection (no converter/inverter), you’ll probably get more time than I did because you won’t be losing energy in a converter. If you set your Resmed humidifier higher or lower you will probably use more or less electricity respectively.All in all, it’s my best option as I don’t want to lug a wet cell deep cycle marine battery that weighs about 50 lbs. into my bedroom in a pinch or on a camping trip. Hope this helps somebody that’s where I was at.
