🧭 Why Preppers Need This
When the grid goes down, your phone is your torch, radio and line to family. A 20000mAh bank keeps phones and small devices running for days without a wall socket. Fully charge it before storing in your kit, and top it up every 2–3 months so it is ready when the power goes out.
📦 Package Includes
- 1 x CHOETECH B729 20000mAh power bank
Accessories or items shown in promotional imagery are not included unless listed above.
⚠️ Important Information & Care
Capacity is about 74Wh, under the common 100Wh airline limit. Carry it in cabin baggage only (never checked luggage) and check with your airline before flying.
Charging speeds depend on the connected device and cable. Recharge time is not stated by the supplier; larger capacities take longer to recharge, so use an 18W or faster USB-C PD charger. A cable is not listed in the supplier's package contents.
Do not expose to heat, direct sun for long periods (other than solar charging where designed for it), water or impact. Do not open, puncture or modify the battery. Stop using it if it swells, gets unusually hot or is damaged. Store partly charged in a cool, dry place and top it up every few months.
