Why is solar charging so slow? — We hear you. Here's the honest answer.
Slow by design. 5W solar won't fill your battery. It extends it — just enough for a call or text when you're off-grid. Sun angle/clouds affect speed, so we keep it real. For daily use, plug into USB-C. For emergencies? Solar is your last line.

How do I recharge the power bank — and which way is fastest?
Three ways:
USB-C port and Micro USB port— fastest, for full daily charges (5-5.5 hrs)
Included USB-A cable — standard (5-5.5 hrs)
Solar panel — emergency backup only (won't fully charge)
Use USB-C for best results. Solar = backup, not main power.
