The world has seen some very failed attempts, quite true to create an Apple Watch bracelet with internal battery: most of them never even got off the ground for lack of technical conditions and possibly consumer interest. The manufacturer Togvuhowever want to change that status quo.
The company launched a campaign for Kickstarter to Batfree, an Apple Watch bracelet that promises to add about 27 hours of life to the watch that, in its current edition, can stay alive on its own for about 18 hours in normal use.
The strap has two internal 300mAh batteries each and makes using Apple Watch a little less comfortable because of its thickness; Its creators, however, claim that the addition in the thickness and weight of the watch is basically unnoticeable in everyday life. To preserve the internal battery of the watch, charging is not continuous: you press a button on the strap to begin charging the device at any time.
Even more surprising is the statement that the accessory does not interfere with any Watch features: According to Togvu, the watch strap does not prevent the sensors on the bottom of the watch from working and preserves heart rate reading, the fall sensor and the unrestrained ECG. no harm. Batfree is made of silicone and has an IP68 water resistance rating, so it can withstand the same weather as the device itself.
The bracelet recharges the watch by the traditional contact method and has a proprietary door for recharging. By plugging in power with the docked Apple Watch, it will charge first, ensuring the health of your internal battery.
Batfree is compatible with Apple Watches Series 2, 3 and 4, and has models for all watch sizes. The Kickstarter accessory campaign is already nearing its goal, and stakeholders can contribute a minimum of $ 45 To secure a unit when it is released, the bracelet cost $ 80. Its creators estimate that shipments will begin in May 2019.
