Finally gave the Anker 737 Power Bank a real test after sticking with RavPower for years
I always bought RavPower packs because they were cheap, but the 737's 140W output actually charged my work laptop from 10% to full in under an hour. The RavPower unit I had would barely keep it from dying. Has anyone else made a jump to a high-wattage power bank that actually worked as advertised?
