## Questions & Answers

**Q: This solar charger can charge my cellphones at night?**
A: No, this portable solar charger can't store the electricity, you need to connect your device to the solar panel in enough sunlight outdoors.

**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/4.8A Max in total, the total theoretical power is 5V*4.8A=24W Max. But there are loss in the solar energy conversion process.

**Q: What's the auto-restart function?**
A: Any cloud or covering arrives may knock the value of output down, but this folding solar panel charger can automatically recover to normal charging speed when there are enough sunlight.

**Q: This solar charger can charge Androids and Apple cellphones?**
A: Yes, but our solar phone charger doesn't include the lightning cable for iPhone or iPad.

### ⭐⭐⭐⭐⭐ Review
*by C***A on 24 April 2026*

Eccezionale!!!! Ricarica solare rapidissima che sfrutta ogni seppur debole raggio di sole. Perfetta con la Power bank Charmast Power Bank 26800 mah, di queste power ne ho acquistate due pure qui per non sprecare neppure un raggio di sole. Un prezzo per entrambi, pinnellino e power, irrisorio per una qualità super, approfittando magari di qualche offerta a tempo. Per caricare velocemente anche un cell Redmi Note 14 pro 5 g oppure un tablet lenovo idea tab plus è ideale. In pratica con il pannellino e le due power mi sono emancipata dalla rete elettrica per ricaricare tutti i dispositivi di casa. Entusiasta.
