The maximum lumens that a 1-watt LED flashlight can have now is 160.
1 watt = 1,000 milliwatts -- take the number of Watt-seconds -- multiply it by 1,000 -- the answer is the number of milliwatt-seconds

1 watt = 1 joule per second.
A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).A Joule is a Watt-second. 2 kilo-watt-hours are 2 x 1000 x 3600 watt-seconds (since kilo means 1000, and an hour has 3600 seconds).

.76 watt
No, you can not use a lower watt charger for a high watt or else the charge wont work
The energy consumption of a modern Cree XP-G or XM-L based flashlight with 170 lumen output can be as low as 1.4 watts with 120 and more lumen per watt. The light output will be approximately equal to a 20 W tungsten incandescent light bulb or a 10 W halogen light.
1 watt will do the job.
Need to see how many amp or watt hours your battery is rated for, many batteries are up to 100 watt hours.your cell phone may hold 1 or so watt hours to give you a comparison. A car battery could maybe charge your phone 500,times before its drained.

Take BTUH and divide by EER. You will get watts.
Consult your laptop's manual or seek this information from the manufacturer of your laptop.
60 watt-hrs= 60 watt*1 hr so it will take 1 hour.
200 Watt Panel
Depends on the battery's mAh rating and what the charger's mA rating is. Say the battery is a 1000mAh Lipo battery and the charger puts out 500mA, the battery will charge in 2hours.
