SW4205U 4.2W 6V USB Output Mono Solar Panel Charger

Hi,
I buy this solar panel charger for a test. Panel is very light and easy to use. You only need usb-micro usb connector for connecting panel with powerbank or phone directly. I use my electrical multimeter and on morning sun panel have charge 6,6 V and 0,8 A, so promised 4,2 W are real. If you want charge phone full it needs time but it is free.
Also it useable for running some unpretentious aplication like LED or decorative element. Another knowledge - usb mini fridge work on solar panel too.

Can't believe this was under £5. I tested the output with a USB current meter and in the UK sun it was outputting a steady 5.5 volts all day. So many solar chargers just don't work! this is incredibly light and portable, take it anywhere. Yes it will charge your phone, but better to plug it into a power pack and let it charge that, It comes with USB so its literally plug and go. I have one with a digital charge level, and yes it took a whole day, but it charged the battery from 0 to 100 %. I'd say for campaign and festival or outdoor use, this could possibly be the best five pounds you ever spend.

Suggestion

none- it's very thin so I assume you have to be careful with it if packing it inside a suitcase/backpack, as it could break, but you could also attach it to the outside and charge on the go!

Para mi sorpresa este panel solar funciona muy decentemente.
En dias nublados coge menos potencia pero si luce el sol la carga funciona estupendamente.
Es ligero y facil de transportar, ocupa poco espacio en nuestra mochila.
Conexiones usb normalizadas para optima compatibilidad.
En resumen, por el precio, es un accesorio muy recomendable.

To my surprise this solar panel works very decently.
On cloudy days it takes less power but if the sun shines the load works great.
It is light and easy to transport, it occupies little space in our backpack.
Standardized USB connections for optimal compatibility.
In summary, for the price, it is a highly recommended accessory.

Me sirve excelente para lo que la compré, carga una batería - lampara pequeña en menos de medio día con buen sol, para cargar celulares me imagino que si se puede pero de los pequeños ya que no alcanza con los celulares que tienen grande la batería.

Suggestion

Ninguna principalmente por su precio

It requires using lower bandwidth WiFi if you have a dual band WiFi but that is a result of Echo only using the shorter range WiFi, a square design mike have been a better design for that purpose

It's a good solar panel, I've try it, works well conception quality is good, I will probably buy it again

Suggestion

Works well to run an arduino, but to use i will try to make a sub solar charger, so I will buy more of these panels

Ziet er simpel, zonder toeters en bellen uit. Wij hebben in Nederland weinig zon de wintermaanden, maar in de zon die wij hebben werk het prima!
