DigitalConcepts
jns Calculate the size compared to the AM 1.5 standard for a one square meter level surface which has 1000 watts of energy impinging on it. If I assume that the actual solar cells cover 0.5 meters by 0.25 meters, the energy impinging would be 125 Watts. Therefore I conclude that the 100 Watts is the total input energy at the AM 1.5 standard. The output energy after conversion and regulation is likely to be around 20 Watts if the cells have a high conversion rate. Rooftop solar panels are greater than one square meter and can get to 300 Watts if the cells have a high conversion rate.

DigitalConcepts in China 100 is really 10 same goes for the li ion batteries, just remove the last zero and that is the true output , ex. 9800 mAh is really 980 mAh
Q: App name? Very important, never see this in the specifications...

DigitalConcepts in pictures shows "Ewelink" App

DigitalConcepts Rule of thumb for anything coming from China regarding power, Drop Off the last zero, in other words this panel is 10 Watts
Q: is it possible to change laser module with another one more powerful?
gefragt von rob.ben auf 2018-02-14 09:58:59
DigitalConcepts yes, be sure to use the power supply controller included with the laser and an appropriate power brick (normally the laser, controller and the power brick are all included with a laser head)

DigitalConcepts Agreed with these comments, IF you are in the business or hobby of electronics :) then you would have a box or 2 or 3 or 4 or ..... with all sorts of spare parts and PS, not hard to find a older laptop with the correct plug, put togeter a portable power supply like I did with 18650 batteries , and a built in recharge port :) :) :)
DigitalConcepts same problems for me, not working on a 12vdc adapter but ok if above 12vdc, ended up using an old laptop power brick so must was not enough current available in the 12vdc adapter and maybe your batteries are low or have a protection circuit to protect from what it think is a short circuit, I did make a 4S pack with 18650 Li-Ion batteries and works fine, the less the voltage the less the wattage

BG531457513 No it is 3Amps. The Chinese incorrectly add the capacity of all the cells together. In fact there are to rows of 5 cells, each cell is 1.5Amps joined together to give 21Volts. The second row is the same also. These 2 rows are connected in parallel so you add the Amp capacity together. Which gives 1.5 plus 1.5=3Amps or 3000mAh. Hope this helps.
