Internal 600mAh Li-Ion battery
That's tiny…
Isn't it the white LED only pull 20ma with 3.2v * 7 of them, which is 140ma per hour. It last for 5 hours or 140ma*5=600ma give or take. So the math does add up, plus you can simple replace/add it with better rechargeable battery (make sure it compatible with solar powered)
…simply leave under car windshield to recharge.
I survive the 'rolling the car' part, but not the wedge of $4.80 torch metal embedded in my eye socket … and it was overcast!
what is the lifespan of those led ?
MUCH longer than the battery - something in the order of 10,000 hours. I have a super cheap 7 LED cheapie which is 3 years old, still going great. I suspect the switch will be the first to fail.
Not a bad idea for camping, leave it charging during the day
I always thought leaving a battery in the heat was a bad idea.
Maybe if you left it in the full summer sun heat that would not be so good, but generally batteries prefer warm temperatures than the cold.
I had one of those solar powered powerbanks for recharging all your devices and the solar panel and battery outlasted the plastic housing, so I only get metal solar equipment now.
Mind you it lasted during the remainder of a moderate summer and all through winter on the dash of the car 24/7 and the following hot summer did the damage.
Will be $5.47 AUD at today's exchange rate
Lithium rechargeable batteries deteriorate with heat. Leaving this flashlight in the summer sun where the aluminium body could easily reach 70C is probably not a good idea. A flashlight for me is something seldom used but must be completely reliable when required. I would take an LED flashlight stored in shade with lithium primary cells that have a shelf life of a decade over this deal.
"Ideal for vehicles, simply leave under car windshield to recharge" No, that's not a good idea. I have seen the plastic casing of my GPS buckle and deform in the heat of an Adelaide summer. I would be worried about damaging the batteries and suffering thermal runaway.
Wasnt a "solar powered torch" an Irish ivention like a decade ago..? Who is laughing now?! :)
