A:AnswerYes this Anker 535 Power battery is charged at 50% out of the box. Therefore, you can try it out in the store and see if it works for your devices.
There is one trick with this device.
I'm finding that it can only charge 1 device at a time if you have it plugged in he wall socket. This is because it is focused on charging up first it won't pass through the power to charge the other devices.
The only way to charge up 2 or 3 devices plug out the anker 535 from the wall.
if you want to charge up the anker and all 3 devices at the same time you will need the anker 747
A:AnswerAnker doesnt make any specific claims to the USB A ports output, I think it's 15W but I could be mistaken. However this bank does not output 65W on a single port, the maximum is 45W on one USB C and 20W on the second usb C for a maximum output of 65W total. the included cable is not labeled specifically but I would expect it is rated for only the 45W maximum output.
A:AnswerThis is really going to depend on how much power draw your laptop has. If your maxing out the powerbanks charge off the highest output port (45W) A good few hours. If your laptop is using more than that it will extend your life but not charge the battery, by how much depends on how much more than 45W you're using at the time. I can nearly double the life of my macbook air with this.
A:AnswerYes, the Anker Power Bank (24000mAh, 65W, 3-Port) should be able to charge an HP Pavilion laptop, provided that the laptop supports USB-C charging and the power requirements match.
A:AnswerIt's a 24,000mAh battery pack, It's got enough charge to mostly charge an Ally X from dead to full. So should be good enough to give you close to an extra full charge. The two USB C ports charge at different rates though, with the main one closer to the outer edge charging at 45 watts, and the one closer to the center charging at 20 watts. So, use the outer USB C port to charge the Ally at the full speed this can deliver to it. Should be fast enough to play and charge without losing battery on the ally.
I have both this battery and the Ally X, and it works fine for me. Though I use this battery pack mainly to extend my playtime on a Quest 3 VR headset. :)
