We stock compact 10000 mAh models for 2 iPhone charges, 15000 mAh for 3 charges and 20000 mAh for travel (4 charges). All models stay under 100 Wh — that's approx. 27000 mAh and allowed in airline carry-on. Class advantage — affordable price, robust lithium-polymer cells, simple operation with LED indicator.

For daily commuting 10000 mAh is enough — that's two full iPhone 15 charges. For weekends or camping pick 15000–20000 mAh. Look for two USB-A ports for simultaneous phone plus headphone charging and a four-level LED indicator (25/50/75/100 %).
USB-A 5V 2.4A delivers a maximum of 12 W to your iPhone — safe standard charging but slower than fast charging. Quick Charge 3.0 reaches up to 18 W on QC-compatible Samsung and Xiaomi devices. For fast charging on iPhone 15+ or MacBook you need a USB-C PD power bank — see our USB-C category.
USB-A 12 W charges the iPhone fully in about 2.5 hours, Samsung Galaxy A-series similar, older Android even slightly faster (4–5 W). The power bank itself refills in 5–7 hours via Micro-USB or USB-C input. Models with Lightning or Lightning+USB-C input let you use the same iPhone cable for power bank and iPhone.
We only stock power banks with CE marking and built-in overcharge, short-circuit and overheat protection. Robust polycarbonate housings, lithium-polymer cells (safer than lithium-ion, no leakage), no no-name knockoffs — especially for value power banks certification is critical for overnight charging safety.
