A good power bank keeps your phone, tablet, or earbuds charged on the go. You don’t need to spend a fortune: under $30 you can get reliable capacity, multiple ports, and solid build. Here’s what to look for and where to shop.
What to Look for in a Budget Power Bank
- Capacity: 10,000–20,000 mAh is enough for 2–4 full phone charges. Higher capacity usually means more size and weight.
- Ports: At least one USB-A and one USB-C; USB-C with Power Delivery (PD) is better for fast charging.
- Brand: Stick to known names (Anker, RAVPower, Ego, Aukey) for safety and durability.
