Milestones in Power Bank Development

The Early Days: Bulky and Basic

Remember when power banks weighed as much as a brick? Early models (2005-2012) offered modest 1,000–3,000mAh capacities with slow 5W charging. They were functional but far from portable—like carrying a paperback book in your pocket.

The Lithium-Ion Revolution

The shift to lithium-ion batteries after 2015 changed everything. Suddenly, we had:

• 20,000mAh capacities in palm-sized devices
• Fast-charging up to 18W (USB Power Delivery)
• Smart circuits preventing overcharging

Today''s Smart Power Solutions

Modern devices are practically energy Swiss Army knives. Take the 2023 models featuring:

• GaN (Gallium Nitride) technology for 65W laptop charging
• Wireless charging pads built into the casing
• Solar charging capabilities for outdoor enthusiasts
