- Please make sure your AC devices not over 100W.
- It maybe have some noise when using some AC devices (such as fans), it's a normal scene.
- As the sunshine not stable while in recharging by solar panle,the capacity indicator maybe will show wrong level and the panel button also will be failure for protection, please only wait for ~5 minutes for revival.
Strict quality control & continuous quality improvment
- We are seriously for every process.

This thing is legit.
I've been using my CPAP on this exclusively for three nights now, probably an average of 7.5 hours a night. I don't usually use a humidifier anyway, and don't have a heated hose. Using a humidifier and or a heated hose will use a LOT more power. I *did* buy a DC adapter for my CPAP (because the AC inverters on these batteries are very inefficient - for maximum life on a single charge you really want to pull DC current). So the DC adapter has a cigarette lighter end style plug, which I attach to the battery using that adapter that comes with it.
As I said, I've run my CPAP now for over 22 hours, and this battery, which came fully charged btw, still reports 3/5 power (from the graphic indicator). I know, obviously that this could be unreliable, but I can definitely say for a 3 day camping weekend, this thing has me covered, apparently easily. I bought a solar panel to be able to recharge it as well, but haven't tried that yet (as I'm still using the CPAP until this thing stops working - I want to know total life).
It's fantastic - totally exceeded my expectations. It's small, lightweight, easy to use, and fits my needs PERFECTLY. The fact that it costs a LOT less than backup CPAP batteries is icing on the cake. If you're looking for a camping CPAP option, or one for power outages, and you're trying to decide on capacity, this one is probably more than enough for you, assuming you use a DC plug and no humidifier/heated hose.
Wanted to follow up. I ended up using it for a 4th night without recharging and so I used it for roughly 30 hours with my CPAP and it still reported 2 bars (40%) at the end. I really didn't want to push it further, but I bet I could have gotten two more nights.
Also, I used my 100W solar panel to recharge it. This is just a rigid panel like the kind you install on your roof. I got it for about a hundred bucks. Anyway, yes, I do live in Southern California, but I plugged the thing in, tilted it sort of in the direction of the sun, and waited. About 6 hours later it was from 40% to 100%.
I can't tell you how happy I am I got this product. Hope this review helps somebody else - there are a lot of reviews that seem knowledgeable here crapping on the product and they almost prevented me from buying the thing. In the end I decided I'd just return it if it turned out to be crap. I wasn't disappointed.
Past week, I finally got to use it on my camping. Make sure your inverter is fully charged. I was able to charge my whole families' phone and a tablet. It also inflated our queen size mattress with the electric air pump. I still had about 50% power left. Emergency light was also a plus during the night time. So far, I have no complains and if something does go wrong, I'll update my review.
Also, here are some pictures of the product that I have taken, so that it will help you know exactly what you are receiving, Thanks!
Lets look at the facts--Battery capacity is 40800 mAh--wow that sounds huge except upon closer inspection that is at 3.7 volts. The inverter and dc power jacks use or supply 12 volts so really the capacity is actually around 12000 mAh or 12 Amp hours at 12 volts. In actual usage, the battery shouldn't be completely discharged--probably to no more than 80%--so actual usable capacity is really more like 9.6 Amp hours. When taking into account inverter losses probably figure on 9 Amp hours at most. Note that with each discharge/charge cycle the capacity is reduced even more (just like your cell phone or laptop battery) until eventually it will not hold a charge at all. The literature specifically says the battery cannot be replaced, so the unit becomes a throwaway. The literature also says it is good for up to 500 charge/discharge cycles--not my experience with lithium polymer batteries especially if they are deep cycled on a regular basis.
So what will they really power? Some have asked about a CPAP machine. Typical battery powered CPAP @10cm water pressure requires 2.5 amps. That will give the user 9/2.5=3.6 hrs usage (not a very good long night sleep). How about a 24 inch LCD TV and DVR? Together they consume about 4.5 amps so if the movie goes any longer than two hours, you have to watch it in shifts between recharge. Mini Fridge--might keep something cool during the day but not much longer especially if you are in and out of the fridge. Coffee Maker--maybe one cup.
The unit claims to be a solar generator. I think solar has been added as a sales gimmick because as far as I can see, the unit is not solar ready.
A 12 volts solar panel in full sun generates up to 18 volts of unregulated DC power. Lithium batteries are very particular on how they like to be charged. Specifically they require a smart charger that controls the bulk, absorption and float phases of the charge cycle. Blasting the battery with uncontrolled power directly from a solar panel will destroy the battery quickly. The literature makes no mention of having an internal solar charge controller so I for one wouldn't try it unless it is from a very small panel (10 watts or less) and then it would take two days of full sun to charge the thing.
So what is it good for--charging my phone, running my laptop for a few hours, powering my electric shaver or other small wattage short duration devices. If that is what you are looking for, then this fits the bill nicely. I gave it three stars for the functionality and knocked off two stars for the deceptive advertising.
