Sonim Introduces Compatibility with GPSLockbox Modular Charging Solution for XP3, XP5s and XP8 Ultra-Rugged Devices

Supports up to five phones and five spare batteries at the same time

Austin, Texas (Sept. 9, 2020) — Sonim Technologies™ (Nasdaq: SONM) devices are now compatible with one of the most versatile multi-device charging solutions in the market for mobile phones. The modular charging dock from GPSLockbox is compatible with the Sonim XP3, XP5s, and XP8 ultra-rugged mobile devices and functions as a five unit phone charger and five unit spare battery charger or as five standalone, single phone and battery desktop chargers.

The modular charging dock was designed for multi-shift operations, offering a drop-and-charge, grab-and-go experience with Sonim devices. For example, the ability to support up to five handsets and five batteries at the same time, allows the multi-device charging dock to support up to 10 Sonim devices and batteries over multiple shifts. A worker may grab a fully charged device, or swap a low power battery for a full power battery. The modular design of the charging dock allows it to support a combination of different Sonim devices if a customer has a mixed deployment of rugged smartphones and feature phones.

“Customer-driven, application-specific accessories are an important part of a rugged mobility solution. We are thrilled that GPSLockbox continues to innovate around Sonim devices,” said John Graff, CMO, Sonim Technologies. “This modular charging dock lets users affordably build custom charging stations thanks to its standalone capability and seamlessly upgrade the dock to support new devices.”

Key features of the GPSLockbox modular charging dock’s compatibility with Sonim’s XP3, XP5s and XP8 devices include:

  • Sonim’s charging pins allow the device to drop into the charging dock and reliably accept power.
  • Each of the five charging units provides power to a Sonim device and an additional spare battery.
  • The solution is available via leading mobile operators in the U.S. and Canada.

The GPSLockbox multi-device charging dock includes a modular design, allowing users to mix and match the phones powered in the five charging slots. The lightweight and space saving compact design allows for easy transportation, storage and deployment. Each of the five charging units includes a visual LED charging status. The dock provides up to 5V/3A power output to each charging slot, and the 110-240V AC power supply is configured for use outside of the United States. GPSLockbox provides a 3-year limited liability warranty on the charging dock.
