The inCharge cable is back with 100W X and X Max variants

RollingSquare is back on Indiegogo with the inCharge X cable. This is an ultra-short take on the common power accessory with magnetic ends that allow it to clip together so as to form a type of keychain when not in use. Its maker has made products of this kind before, but asserts that this new variant is primed for the future of smartphones and laptops.

This is because some Snapdragon 888-powered devices could be capable of 100 watt (W) charging in 2021. RollingSquare claims that the inCharge X can also support this ultra-high rate despite its diminutive length. The idea is that one smartphone (or laptop) could charge another through this connection.

This is due to the 6 aramid fibers, wrapped in braided copper, which are coated in TPU inside the cable's outermost nylon-mesh covering, of which the X is made. It has versions that have either type C; type A; interchangeable USB; microUSB or Lightning ends. However, the latter can only charge iPhones at up to 18W.

The tiny inCharge X might also prove an alternative to reverse wireless charging for a user's TWS earbuds case or other USB-powered gadget. This time around, however, RollingSquare has also prepared a version of this product with a "normal" length. This 1.5m inCharge X Max also has interchangeable ends, but might also charge a 96W MacBook Pro in about 98 minutes.

The new accessory series currently starts at US$15 for an X or $19 for an X Max. It has already attracted over $197,000 on its crowdfunding platform, with 37 days to go on its campaign.
