How does the magnetic design work?

OCOOPA states the two hand warmer units connect magnetically when stored together in a pocket, making them easy to carry as a single unit. They separate when needed to provide one warmer per hand during use.

Can these genuinely charge a smartphone?

OCOOPA states the 10,000mAh battery can charge most smartphones — a typical modern smartphone has a battery of 3,000–5,000mAh, meaning the warmers carry enough capacity for approximately one to two full phone charges alongside providing warmth. Charging speed will depend on the output port and cable used.

How long does it take to recharge the OCOOPA hand warmers?

Check the current Amazon UK listing for the specific recharge time for this model. With a 10,000mAh battery, recharge time via standard USB will typically be several hours — using a faster charger where compatible will reduce this.
