Support reviewing offgride tech

Would like to test some bits from banggood for cheap offgride life. If you would like to push me a donation on the button on the left would help to make this happen.

Here are 2 potentially useful pieces of off grid kit


12000mAh 12V Car Jump Starter Car and laptop/USB Power Supply Battery


In theory this should charge off a portable solar panel, and run a laptop and any USB device. Almost all of these will fail to charge off 12-14v needing 16-19v to charge properly, this one says it will charge off a boat/car (12-14v) so good to test if this is true so I can recommend it as a backup winter boat/summer travel power source.

Nitecore MH20 CREE XM-L2 U2 1000LM USB Smallest LED Flashlight 18650



This would not only make a good flash light for dark nights on the tow-path it would make a good anti mugging device to scar away undesirables 1000 lumen is blighting bright. The current touch i use for this is only 70 lumen which works fine. This charges by USB so easy plug and forget no battery’s to replace.  Will it work? Hands on testing is the only way to tell.
