What ESR does

ESR (stylized as ESR TECH) is a global consumer electronics accessories brand founded in 2009 and headquartered in Wilmington, Delaware, with Shenzhen, China operating roots. The company designs and sells a portfolio of device accessories organized across five core categories: protective cases for iPhone, iPad, AirPods, and Samsung Galaxy devices; screen protection including the proprietary Armorite line; iPad productivity accessories such as the Shift Keyboard Case, MagMouse, and Geo Digital Pencil; wireless charging products under the HaloLock and CryoBoost brands supporting Qi2 25W with active cooling; and MagSafe-compatible wallets including Find My-integrated variants. The product line is differentiated by proprietary technologies — CryoBoost cooling, HaloLock magnetic attachment (rated up to 3,200g holding force), Armorite screen protection (7x standard), and Apple-certified Find My integration — the last of which made the Geo Digital Pencil the first third-party stylus to receive Apple's Find My certification.

ESR operates a primarily product-led, direct-to-consumer go-to-market motion. Sales flow through Amazon marketplace globally (with Prime eligibility and Prime Day promotional placement) and ESR's own regional storefronts across more than 50 countries in North America, Europe, Asia Pacific, and the Middle East. The company also runs the Super User membership program (free to join, points-based, referral cashback, 15-20% exclusive discounts) to drive retention. Pricing is unit-based across a wide tiered range: cases from $8 to $90+, iPad keyboard cases from $65 to $190, wireless chargers from $6.50 to $170+, and the Geo Digital Pencil at $32.99-$35 versus Apple Pencil Pro at $129. Customer segments are horizontal-consumer (mass-market iPhone, iPad, Samsung Galaxy, AirPods users) with no named enterprise accounts.

The company is privately held and led by CEO Tim Wu, has won Red Dot Design Awards for four consecutive years (2023-2026), was named to Fast Company's Most Innovative Companies in Consumer Electronics list in 2025, and claims a 130M+ global user base per its CES 2026 disclosures. ESR is structurally tied to OEM device-release cycles (Apple and Samsung flagship launches) and the broader MagSafe/Qi2/Find My standards ecosystems, which dictate product cadence and certified interoperability. A 2023-vintage lithium-ion battery recall on the HaloLock Kickstand Wireless Power Bank (Model 2G505B), flagged by South Africa's National Consumer Commission after nine fire/explosion incidents, is the only material regulatory event disclosed.
