How does the retractable cable work?
The USB-C cable lives inside CHAMP Stretch. Pull it out to the length you need, up to 2ft, plug into your phone, and when you're done a quick snap retracts it back into the body. No loose cord to coil, tangle, or leave behind.
Can CHAMP Stretch charge two devices at once?
Yes. Use the built-in cable for one device and the extra USB-C port for a second. When both are in use each gets 5V/3A (15W), so a phone and a pair of earbuds or a watch can charge together. For the fastest single-device charge, use one at a time to get the full 30W.
How fast is 30W, and what will it charge?
30W USB-C Power Delivery (up to 20V/1.5A) is enough to fast-charge iPhone 15/16/17, Samsung Galaxy, Google Pixel and iPad at their top wired speeds, and it handles Apple Watch, AirPods and any other USB-C device. It is built for phones and tablets rather than laptops, for MacBooks, CHAMP Pro's 65W is the better fit.
How many times will CHAMP Stretch recharge my phone?
With 10,000 mAh on board, expect about two full charges for most current iPhones and Android phones once you allow for the normal energy loss during charging, enough for a long day out, a flight, or a weekend of top-ups for earbuds and a watch.
Can I bring CHAMP Stretch on a plane?
Yes. At 10,000 mAh, CHAMP Stretch works out to roughly 36Wh, well under the 100Wh limit airlines and the TSA set for power banks in carry-on bags. Like all lithium-ion batteries it needs to travel in your carry-on, not checked luggage.
How do I recharge CHAMP Stretch, and do I need a separate cable?
No extra cable needed, plug the built-in retractable cable into any USB-C wall charger, or run your own USB-C cable into the port. Both accept up to 20V/1.5A (30W), so a 30W-or-higher USB-C PD charger such as WALLY Stretch 35W will refill it fastest.
