Questions about this item

What are the exact dimensions of the W1148 power bank?

The power bank measures 5.71 inches by 2.68 inches by 0.51 inches and weighs 240 grams, making it slim enough to carry alongside a phone.

How do I recharge the power bank using the built-in input cable, and what wall charger do I need?

Plug the attached USB-A input cable into a wall charger rated at 12 watts or above; a full recharge takes about 6 hours.

When will the internal lithium-polymer battery need replacing, and can I do it myself?

The sealed 10000mAh lithium-polymer cell is not user-replaceable; after several hundred charge cycles the runtime will gradually decrease, at which point the whole unit should be recycled.
