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. ## Features - Packed with features. - Cutting-edge technology. - Designed to Perfection. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071G4CQSR | | Amperage Capacity | 1 Amps | | Best Sellers Rank | #54,520 in Electronics ( See Top 100 in Electronics ) #5 in Mobile Phone Solar Chargers | | Brand | BigBlue | | Brand Name | BigBlue | | Connector Type | USB | | Customer Reviews | 4.2 out of 5 stars 1,726 Reviews | | Efficiency | High Efficiency | | Folded Size | 40.6 x 11 x 0.2 inch | | Global Trade Identification Number | 00768390608786 | | Included Components | solar charger with digital ammeter waterproof foldable dual usb | | Item Dimensions L x W x H | 28.4L x 16W x 0.5H Centimeters | | Item Type Name | solar panel charger | | Item Weight | 595 Grams | | Manufacturer | BigBlue | | Manufacturer Part Number | 1 | | Material | Monocrystalline Silicon | | Material Type | Monocrystalline Silicon | | Maximum Power | 28 Watts | | Maximum Voltage | 5 Volts | | Model Number | B401E | | Output Voltage | 5 Volts | | Product Dimensions | 28.4L x 16W x 0.5H Centimeters | | Special Features | Waterproof | | UPC | 768390608786 | | Unit Count | 1 Count | ## Product Details - **Brand:** BigBlue - **Material:** Monocrystalline Silicon - **Product Dimensions:** 28.4L x 16W x 0.5H Centimeters - **Item Weight:** 595 Grams - **Efficiency:** High Efficiency ## Images ![5V 28W Solar Charger With Digital Ammeter Waterproof Foldable Dual Usb Ports Solar Battery Charger For Iphone 8/X/7/6S, Ipad Pro/Air 2/Mini, Galaxy S8/S7/S6/Edge/Plus, Lg, Nexus, Htc - Black - Image 1](https://m.media-amazon.com/images/I/81OfMkn5UyL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by P***R on 22 September 2023* Excellent performance ### ⭐⭐⭐⭐ Best Solar Charger for Trekking and Emergency use *by V***R on 11 December 2023* Its worth what you pay for, i know its expensive than other solar charger but trust me its totally worth it.
