The pocket-sized Pirl Charger is the world’s most powerful 4-port USB charger. Made from aluminum and FR4, it delivers 2.7 amps per port and 50 watts total, operating with 4 separate channels, so there’s no throttling to slow things down. As a DC input charger with 7 to 17V input voltage, you can power it from multiple sources with the appropriate adapter, unlike other chargers that only work with wall outlets. Seems legit. Maybe that’s why it funded on Kickstarter in just 9 hours.
