## Description

Product Description

Review: Good - Excellent performance
Review: Best Solar Charger for Trekking and Emergency use - Its worth what you pay for, i know its expensive than other solar charger but trust me its totally worth it. I have used other cheap solar chargers but they barely do what they say and have a very bad build quality. I bhought this S-Charger for trekking and emergency use but please do remember to carry powerbank with you and charge only the bank with it, becouse current fluctuate a lot during charging its better to use power bank so that your main phone or device doesnt get damaged. During testing i got 1.8 max amp that to during slight overcast day but in direct sunlight i am sure it will touch 2-2.4amp. Please go for this S-Charger without a doubt. Edit- After using it for few days i would say this is a must to have solar kit for everyone and few things i noticed :- 1. Total amps that you seen on solar charger ampmeter is depends on the device you are charging + how much sunlight you are getting. 2. My pixel 7 pulls around 1.8amp and samsung around 1.5 but my Mi Hypersonic powerbank pulls around 3amps(Sample attached). 3. Pixel 7 gets charge from 30% to 90% in around 80-90min, yes this solar charge is that efficient which was shocking for me as well.

## Questions & Answers

**Q: If cloud or shade passes,  does solar charger automatically recover or does it stop charging?**
A: Yes, this 28w solar panel charger can automatically recover to charge your phone

**Q: This solar charger can charge Androids and Apple cellphones and power station?**
A: BigBlue 28w solar panel charger can charge most Androids and Apple cellphones, but our solar phone charger doesn't include the lightning cable for iPhone or iPad. This product comes with 2 5V USB-A output, so it can't charge power station.

**Q: Why the real output is different from the power claimed?**
A: This product has 4 piece panel, each is 7w, so the power is 4*7w=28W;  Theoretical output is 5V/2.4A Max for each port, 5V/4.0A Max in total, the total theoretical power is 5V*4.A=20W Max. But there are loss in the solar energy conversion process.
