An alternative to solar powered chargers that rely on the sun to generate electricity.
Solar powered generators don’t work at night or in the shade. Our hand crank generator, it works all the time, at night and in bad weather when the sun is not available.the MAXOAK P40 power bank can make a difference between life and death in natural disasters that interrupt electricity. You can generate electricity by hand power when electrical sources are unavailable.

It is the conversion of energy from sunlight into electricity. So long as there is sunlight, you can have the power bank recharged no need extra charging cable. It is a completely clean and renewable energy source.especially suitable for Outdoor enthusiasts.
What you get: one power bank, one USB cable, one user manual.
7800mAh, 1*5V2A input, 1*5V2A output.
For solar panel, it is 1W (5V 0.215A). and this power bank support solar charge.
No, it is not waterproof.
The betters cell inside the product can not be replaced by yourself.
Yes. It via recharged by
solar, you can put it under sun, So long as there is sunlight it will
Be recharged by itself no need other charging cable or others. And you can also recharged it by hand crank /winding . This is for emergency if there is no sunlight or ac wall outlet but the recharging speed is slower than solar and ac wall outlet.
Adapter not include, charging cable is included.

Its small (see photo of it in my hand)
You can charge it at home, use it, put out for solar charging, and hand crank it in an emergency.
The hand crank feature is a nice little addon that doesnt get in the way or impede any other function of the charger. Which is a great thing.
Perfect for me for camping.
Just received the solar power bank. This is my first solar powered external battery so I don't have any others to compare it to. Product came fast and neatly packaged. It came at around 84% charged for me. There are three ways to charge it: 1) normal wall outlet (5.0V/2.0A input); 2) solar energy; 3) hand cranking it. The hand cranking is pretty much meant for emergencies. It doesn't say how long I need to hand crank it though. I cranked it for a good minute before getting bored, but the battery level stayed the same. I probably won't be charging it much this way, but I think I'll at least be able to get some decent juice in if I crank it for 5 minutes. I plan to charge it primarily from the sun by just leaving it on my car dashboard. Hopefully this will make it more convenient since I kept forgetting to charge my non-solar external battery charger at the times I needed it the most. I am hesitant to keep it there for too long though due to fear of overheating. I'll update my review after I've experienced charging it from solar energy. I want to see how long it takes to charge from 0 to 100% from solar energy alone. In 10 minutes so far the power bank has charged iphone by 20% and the battery level has only gone from 84% to 83%. So far so good.
This device is a well built, compact charger. I have only had it a few days but, I fully charged an iPhone 6 Plus while only using about a third of this device's power. The crank is not too hard to turn...I haven't tried to see how much it can be charged over a given period of time. It seems to charge back up in a reasonable amount of time. I have only had it in the sun for a few hours, but it seems to charge pretty quickly...as with the crank, I haven't tested the solar recharge under scientific conditions. Altogether, I like this device and believe it will be an asset on long bike trips/hikes.
I'm pretty please with this item. It's bulky, but 7800mAh is going to be. The crank is pretty useless in terms of real recharging, and I hope to never find myself in need of using it that way. The solar trickle charge is just that a trickle, but I leave it in the window at home and it charges pretty reliably over the course of a week. I bought it as backup of sorts after we had a nearly 24 hour power outage over the winter but it's now part of my commuter pack. I play several mobile games and the Pixel XL sucks juice like no other, particularly when I tether my kids phones for playing pokemon go. I get probably 2, maybe 2.5 full charges on a Pixel XL or about 4 hours continuous run time playing and end up with a full cellphone battery at the end of that. I would definitely buy again.
I got this and sent it to an acquaintance living in Puerto Rico who lost his home during the hurricane. Now he can charge his phone and have some light after dark. My friend has thanked me profusely several times for providing him the ability to stay in contact with his family during the hurricane recovery operations.
This is a great portable power bank that is small enough to carry around with you. I was surprised with the how compact it was and really like the versatility of it. This power bank can be charged by an AC outlet via the included charging cable as well as a neatly tucked away hand crank which would be great in the case of an emergency. The hand crank can be cranked either clockwise or counterclockwise so it can be charged easily be both lefties and righties. This power bank can also be charged via a built in solar panel which will be helpful when I am camping and an AC outlet is not available. There is one USB output port which puts out 5v at 2amps which worked great to charge my iPhone 7plus as well as my iPad. With this 7800mAh battery pack I will be able to charge my phone multiple times before having to recharge the the battery pack.
It is great little charger. Solar charting is very handy. Hand cranking is provided for the emergency situations. But be clear that it is for emergency situations and wont give you a lots of charge. As advertised on the package itself, it gives 5 minutes of talk time for 30 minutes of crank. Which should be good enough for emergency situations. It also has a battery charge indicator in percentage which is great. You can notice the increase in percentage when you crank the charger (although pretty slow as said earlier).
So far so good. After a day or two of solid charging, it has just reached 100% from usb charging. Probably going to have to get a water tight case for it when I go camping. I will update on this after I do, or if I drop this ( Hopefully I won't ).
I love it so far. It has gone on two campouts and performed well by lasting after charging it by AC. It did well in the sun and partly cloudy days. I have yet to try the Hand crank but I love that I have that option. In y family we have Samsung note phones 8 and 5 and my son has the S7 active and it charged them well
