聽音樂、玩手遊、傳訊息，現代人的生活與手機密不可分，因此，人們常會因電量快用完而感到焦慮，而為了避免這種情況，不少人會隨身攜帶一個或多個行動電源，以備不時之需。然而，你是否有「沒帶充電線」或「帶錯充電線」的經驗呢？只能眼睜睜地看著手機陷入沈睡。

為了解決這個惱人的問題，台灣團隊倍加能（BEZALEL）開發了「Prelude 智能感應無線充電行動電源」，此款行動電源採奈米吸附技術，無需增購任何手機配件，便會自動黏在你的手機背面。與目前市面上的行動電源和無線充電座相比，Prelude 成功改寫規則，提供消費者真正的「無線」生活。

Prelude 就連開機方式也很特別，採用「智能感應式的開關設計」，只要輕輕一搖就能開機，無需倚賴任何按鈕；為避免耗電，靜置十五秒以後即自動關閉。

在產品規格上，Prelude 的厚度只有 17mm、重量則約 155 克，與一般的行動電源差不多。唯一美中不足的是，比起小米等現有品牌都推出 20000mAh 的大電池容量， Prelude 只有 5000mAh，以頻果最新推出的 iPhone XR（2942mAh）為例，僅能提供 1.5 次的完整充電。

團隊在 2014 年有了初步成果後，將 Prelude 放上募資平台Kickstarter，一上架就引發熱潮，45 天即獲 13.2 萬美元（約 430 萬元台幣）的贊助。而之後推出一系列無線充電相關產品，更被 DigitalTrends, Business Insider , Wired 等美國媒體選為年度最佳無線充電器。Prelude 的背後開發團隊來自台灣，創辦人-吳哲民初期只覺得好玩，沒想到開啟了創業之旅，成為了南加大第一個投資的台灣團隊。
