自誕生以來，Apple Watch 的一大缺點就是電量，以至於用錶帶充電也成為了一種可能的想像。前不久，第三方錶帶商 Reserve Strap 爆出了 Apple Watch 設計的隱藏接口，並開始利用這個接口研發可充電的錶帶。今天，Researve Strap 披露了Apple Watch 第一款可充電錶帶的產品細節：

• 寬 25mm，厚 3-9mm，重 65g
• 38 mm 和42 mm 兩種尺寸，適用於130-210mm 的手腕
• 黑白灰三色
• 能通過Micro USB 同時給錶帶和手錶充電
• 為 Apple Watch 增加 30 小時的電量

Reserve Strap 通過手錶中隱藏的6-pin接口給手錶充電。錶帶上有一個電源鍵和電源指示燈，按下電源鍵就可以開始充電過程，大約60-75 分鐘就可以充滿。

加上 Apple Watch 自稱的18 小時待機時間，可以讓手錶的待機時間達到48小時。

它也能為 Apple Watch 增加無線磁感應之外的另一種充電方式，外出時可以當作移動電源，在沒電的時候換上即可。

Reserve Strap 稱，這款錶帶完全符合蘋果對第三方錶帶的設計指南，不會影響手錶的保修。不過蘋果從始至終都未提及過這個6-pin的內部接口，在設計指南中也未提及它的作用。

好消息是這款錶帶今年11月3日就能發貨，壞消息是它的價格比較貴，249.99 美元，已經夠買半塊最便宜的 Watch Sport 的了。

Following a number of teases for its third-party Apple Watch strap with a built-in battery pack, Reserve Strap, bound to be one of the first battery straps for Apple Watch, is promising an additional 30 hours of battery life for Apple Watch users as it announces plans to ship in November.

In an update on its website, the company announced that the final design for Reserve Strap will offer “more than 30 hours of additional usage,” or 2.7x or 167% of the Apple Watch’s built-in battery.

One of the biggest complaints regarding Apple Watch at launch was the necessity of charging once a day for most users. Reserve Strap will bump that up to once every three days or so, and even up to a week for some users that are using the device less frequently.

In addition to being one of the first battery straps for Apple Watch, the product will be one of the first to tap into the device’s not-so-secret hidden port, opposed to using Apple’s own magnetic, inductive charging solution. The company previously noted that using the port will allow for faster charging while allowing them to avoid interference with sensors on the back of the watch in their design.

The Reserve Strap will come in three colors — white, grey, and black— and will be available for both the 38mm and 42mm Apple Watches with the same specs for both in terms of additional battery life time. It will also be “as resistant to water as Apple Watch,” addressing one of the concerns several readers mentioned when we first told you about Reserve Strap. The company will send a micro USB cable for charging the strap (charging won’t require disconnecting the strap from Apple Watch), as well as a special tool for removing the door on the hidden port that Reserve Strap connects to for charging.
