Designed and conceived by Shaun Teblum and Rob Gold, the pocket sized bKey is currently seeking finances through [Kickstarter](https://www.trendhunter.com/trends/automotive-wireless-phone-charger), a crowdfunding site. The emergency [iPhone](https://www.trendhunter.com/trends/smartphonecharging-smart-wallets) charger is especially handy as it [attaches to your key chain](https://www.trendhunter.com/trends/nomad-chargekey-v2). The small white device does not require any charging cables because the connectors are located on either end of the smartphone battery. The built-in USB tip makes it extremely easy to use and makes charging on the go more portable than ever. It is intended for a backup charge, however, rather than a full powering up. The bKey will give you enough juice for a 30 minute conversation and will hold its charge for up to 30 days. ## Trend Insights (Trend Hunter) - Score: 3.0/10 - Popularity: 36% | Activity: 45% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Mobile](https://www.trendhunter.com/mobile) ## Key Themes ### What's Driving This Trend - **Compact Wireless Chargers:** Opportunity to disrupt the charging industry by creating more compact and portable wireless chargers. - **Keychain Attached Chargers:** Opportunity to disrupt the accessory industry by designing keychain attached chargers for smartphones and other devices. - **Crowdfunding for Tech Accessories:** Opportunity to disrupt the financing industry by utilizing crowdfunding platforms to fund innovative tech accessories. ### Who This Affects Most - **Charging Solutions:** Disruptive innovation opportunity for companies in the charging solutions industry to develop wireless and compact emergency chargers for smartphones. - **Tech Accessories:** Disruptive innovation opportunity for companies in the tech accessories industry to create keychain attached chargers for smartphones and other portable devices. - **Crowdfunding Platforms:** Disruptive innovation opportunity for companies in the crowdfunding platform industry to support and showcase innovative tech accessories through their platforms. ## Related on Trend Hunter - [Micro-Sized Smartwatch Chargers](https://www.trendhunter.com/trends/keychain-apple-watch-charger.md) - [Smartphone-Charging Smart Wallets](https://www.trendhunter.com/trends/smartphonecharging-smart-wallets.md) - [Folding Multi-Position Charger Cables](https://www.trendhunter.com/trends/keychain-charger-cable.md) - [Grip-Enhancing Smartphone Batteries](https://www.trendhunter.com/trends/popsockets-popgrip-jumpstart-lightning.md) - [Feature-Packed Key Chain Chargers](https://www.trendhunter.com/trends/high-six.md) - [Rapid Phone Charging Solutions](https://www.trendhunter.com/trends/swapperys-external-smartphone-battery.md) - [Professional Device-Charging Notebooks](https://www.trendhunter.com/trends/wireless-charging-notebook.md) - [Compact Foldable Chargers](https://www.trendhunter.com/trends/kuxiu-k1.md) - [Clip-On Phone Power Banks](https://www.trendhunter.com/trends/nano-power-bank.md)
