- How many times can it charge a phone?
- With 10,000mAh it typically gives a modern phone about one and a half to two full charges. Real output is lower than the rated capacity because of conversion losses.
- Does it support fast charging?
- No. It tops out at 2.4A over USB-C, which is standard charging speed. Phones that need USB-C Power Delivery will charge slowly.
- Can it charge a laptop?
- No. The output is too low for laptops. It is meant for phones, earbuds and small accessories.
- Can I take it on a plane?
- Yes. At 10,000mAh it is well under the usual 100Wh carry-on limit, so it can go in cabin baggage.
- What comes in the box?
- Expect the power bank and a short charging cable. A wall adapter is not included, so you need your own USB charger.
- How do I know how much charge is left?
- There are basic LED indicators rather than a percentage display. They show roughly how much power remains.
- Where is the Shein 10000mAh Ultra Slim Portable Charger Bank cheapest?
