Q: How long does it take to fully charge a PowerPack 20000 power bank itself? Can you charge it with your laptop's charger?
A: If your laptop's power brick supports USB Power Delivery, then you can recharge the power bank via your laptop's power brick. Apple 29W, 30W, 61W, 87W, and Google Pixelbook's charger all work well with the power bank. The recharge time depends on the power brick used. Here are some examples: 3.8 hours via a 45W PD power brick, 5.5 hours via 18W charger, and 8.8 hours via 10W (5V/2A) charger.
