This is a video going over the LFP 20 Portable Solar Power Generator System showing how it works and how to get the most out of it.
What Is LIFEPO4? The Benefits Of Using LIFEPO4 Batteries. -
+ Safe Technology – Will not catch fire or explode if damaged.
+ Half the weight of an equivalent capacity lead acid battery.
+ Over 2000 deep discharge cycles vs. 300 for lead acid battery.
+ Double the usable capacity of lead acid batteries.
+ Virtually flat discharge curve means no “voltage sag”.
+ High discharge & recharge rate capability.
+ They can be left partially charged for long periods of time.
+ Extremely low self discharge rate unlike lead acid batteries.
+ Does not suffer from thermal runaway like Li-Ion or Li-Po
+ Can be safely used with no loss in performance up to 140F.
+ Absolutely maintenance free for the life of the battery.
+ Does not contain any toxic heavy metals like lead & cadium.
+ The most eco friendly battery chemistry available.
What Is MPPT Solar Tracking? – The most widely known advantage is an increase in useable power going into your batteries from a photovoltaic array. When a photovoltaic module is connected in a system which has a battery, the battery acts as a limiter to the voltage output of the array. A MPPT charge controller “fools” the panels into producing a higher voltage by “eliminating” their view of the battery in the system. This way they operate on their maximum power point voltage. This allows more power to go into the battery, up to 30% in some instances.
Reports from the field indicate that increases of 20 to 30% in total daily solar power harvest are typically observed by using MPPT solar tracking technology vs. systems lacking MPPT technology.
This style of solar chargeable flashlight has a bit of a history with many of them using non rechargeable batteries and fake, reject or unconnected solar panels. So take a gamble. Is this one real or fake?
The listing this one came from is:-

Spoiler below:-
The flashlight is a good source of parts like the small solar panel that puts out useful current, and the LIR2032 rechargeable lithium button cell with tags. The solar panel puts out a surprising 8V open circuit and 20mA short circuit when tested against the front of a 20W LED floodlight. The PCB is glued to the solar panel and may damage it if removed, so probably better left on, even if the components have to be removed to make it flatter.
