Something I did not add to the review when first noted is a note on a USB load inducer, which is also utilized in testing. 34000 MaH at 5V, and higher at the 3.7V rate (around 46,000), which is a huge output level.
The Kayo Maxtar 6-port 50,000 mAh ultra-high capacity charger is a force to be reckoned with, and I say that as someone that is obsessed with power banks as of late. This is the 31st power bank I have owned and the largest by and far, and it is also the only one I have truly been able to keep multiple devices including a laptop charged with because of the sheer amount of charge this is capable of holding.
Before beginning the review, I want to note that this is the 3rd item I have tried from this manufacturer and each one has done remarkably well. I utilize a variety of testing methods to make certain that all ports are within their parameters, that everything works properly including regulation and powering down, and they have all done remarkably well here. I take the testing of items that I place my devices in contact with VERY seriously, too, because any subpar performance is unacceptable. I have also been happy with their ability to fielding questions and in relating information.
Here, you have a 50000 mAh charger with 6-ports suited to charge quite a few different device types. You have 2 5V/1A USB outputs for action cameras and phones, 2 5V/2.1A USB outputs for charging tablets, a 12V output for cameras, and a 20V output for laptop charging.
With regard to laptop charging, you need to check the power bank attached to your laptop and figure this at +/- 5% (or equal) to see if your V will work. If you have any questions on fit, you can contact Kayo Maxtar and they can help you there as well.
When it comes to mAh and device charging, you should consider the battery type to determine the amount of charges supplied. This is a simplified method and does not take into account a number of variables, but say the Samsung GS5 has a 2900 mAh battery in it and your camera has a 2100mAh battery in it. If both are almost depleted, you can get a feel for how long 50,000 mAh will last. Some items tout huge numbers, too, but this actually does deliver on the numbers it is touting, which is very impressive.
Equally impressive is the way this is designed, with it being nice quality and durable and also smaller than I envisioned. It is going to be larger than a 13,000 mAh charger, per say, but it was far lighter and more compact than I envisioned. I say this as a great thing, too, and something I was impressed by.
This comes with a number of ends for device attachment, and a power plug for the device, a carrying case as well.
