A 20,000mAh power bank built for real days — two full phone charges, 22.5W fast-charge output, and a shockproof shell that survives the bottom of a backpack. Pass-through charging lets you top up the bank and your phone at once.
The BoltCharge 20K is designed for people who genuinely run their day off their phone — long commutes, load-shedding evenings, weekend trips. Dual USB-C/USB-A output means you can charge two devices at once, and the LED display shows exact battery percentage instead of a vague four-dot guess.
