- How many times can it charge a phone?
- At 10,000mAh, expect roughly two full charges for a typical phone, less if you charge two devices at once or lose energy to heat.
- Can it charge a laptop?
- No. Its output is aimed at phones, earbuds and small accessories, not laptops that need higher USB-C Power Delivery wattage.
- Does the USB-C port charge devices or only the bank?
- It works both ways on this model, but check the rated output before relying on it for fast charging a phone.
- What's in the box?
- The power bank and a charging cable. A wall adapter is not included, so you'll need your own USB charger.
- Is it allowed on a plane?
- Yes. At 10,000mAh it is well under the 100Wh carry-on limit most airlines set, but keep it in your cabin bag, not checked luggage.
- Where is the Energizer UE10035C 10000mAh Portable Power Bank cheapest?
- At Best Buy, for $14.99, as of our latest check.
