You always want the power supply (Apple wall wart) to have a greater current capacity than the load (Fenix lantern.)
1A < 1.5A.
Get the Apple 2.4A 12w wall wart and be done.
Thanks, I have always used 123's and the whole 18650 kinda spooked me. I initially tried the 1a Apple charger and it got pretty warm after a few minutes. Figured I better get on this forum and quiz someone.
Any idea what the output on a USB would be on a laptop?
Chris, thanks for the info. Apple 2.4 for me. I think I will like the little lantern with the 18650 set up. Also the new 2.4 will charge my Iphone 6 and IPad Mini a lot faster. Whats not to like.
Actually I doubt you are going to do any damage to the USB rail on the computer power supply by overloading a USB port. The experience I have had is that each USB port incorporates overload detection. If you exceed the capability of the port, you get a warning message from the USB driver that you have exceeded the current source capability of the port, and it quite literally turns off the port, ending the overload instantly. That protects both the USB port and the power supply.
That's the theory anyway. The USB spec does require overload protection. But some poorly designed motherboards and laptops do get fried occasionally.Actually I doubt you are going to do any damage to the USB rail on the computer power supply by overloading a USB port.
