MiniMax Series

Secure storage, charging, and sanitizing of classroom devices

EarthWalk’s MiniMax series features budget-minded, small footprint with many optional configurations. Solid construction using welded steel—as opposed to plastic materials—means our carts are durable and secure. Horizontal storage greatly reduces wear and tear of devices.

MiniMax allows you to store, secure, charge and deploy laptops and Chromebooks as well as most Ultrabook, Netbook and Tablet devices.

Carts are available as a pre-wired charging cart solution, which means less hassle for you and complete plug-n-play technology right out of the box.

MiniMax accommodates our optional CleanZone device sterilization package: safely and efficiently sanitize devices using ozone. This innovative and highly effective method decontaminates all of the devices within the sealed cart in minutes without any residual chemical or scent. Tests have shown that UV light is not able to penetrate all components of devices unless directly exposed to the light. The FDA, USDA and EPA have approved ozone as an antimicrobial disinfectant, killing 99.9% of pathogens. Ozone dissipates back to pure oxygen when the cycle is complete.

Configuration Options

Charging Systems

AC Smart Bar
For budget-minded consumers, EarthWalk labs can be configured with AC power outlets in each storage compartment for use with each device’s AC adapter. But this is no basic power bar: EarthWalk has staggered the sockets in a zig-zag formation, ensuring that adapters will not block other sockets. NOTE: When using AC adapters to charge devices’ internal batteries, it is possible that all devices may not simultaneously charge. Depending on your device, this solution may require an electric timer to safely switch between groups of devices to prevent overloading the electrical circuit.

Digital AC-SMART Switching System
Deployments using devices’ AC adapters for charging can be configured with EarthWalk’s Digital AC-SMART Switching system. This system can auto-sense the amount of electrical draw required by each device’s AC adapter and safely switch between groups of devices to prevent overloading the electrical circuit. The digital smart switching system will monitor and continue increasing the number of devices that are being simultaneously charged to help shorten the total lab charging cycle.

Pre-Wired Solutions for USB Type-C
USB-C is the latest standard in charging portable devices, and EarthWalk has you covered. We can pre-wire your carts and stations with our certified USBC-PD adapters or you can supply us with your existing AC adapters—either way we’ll take care of the wiring headache for you. Literally plug-n-play as soon as your order is delivered to you. Combine USB-C with our AC-SMART system, and we can provide managed charging power for all of your devices from a single power cord, charging all your devices as quickly as possible and eliminating the worry of overloading your electrical circuits.

iCharge – Powered USB Charging for iPads, Tablets or USB-C Devices
Select EarthWalk’s iCharge package and create our pre-wired USB charging solution. The iCharge solution features a high-efficiency central power supply system with ten USB 5V 2.4A charging ports. Additional iCharge systems can be daisy-chained to increase system capacities. Pre-installed USB, USB-C or Lightning data cables in each storage compartment make deployment and support convenient.

HE-PD – High-Efficiency USBC-PD Charging System+
EarthWalk’s HE-PD package is a pre-wired USBC-PD charging solution featuring a high-efficiency central power supply system with six USBC-PD auto-sensing, multi voltage (5V,9V,12V,15V) charging ports. Additional HE-PD systems can be integrated to increase system capacities. Pre-installed USB-C or Lightning data cables in each storage compartment make deployment and support convenient.

HE-Z – High Efficiency Charging System+
This patented system provides the most energy-efficient and easy approach to charging groups of laptops+—no AC adapters needed! EarthWalk’s High Efficiency (HE) charging integrates a central power supply and control circuit board system to distribute simultaneous power to every device with up to 85% more energy efficiency than charging with AC Adapters. HE-Z charging cables can be easily swapped when devices are changed or updated and this system also allows multiple brands of devices to be stored and charged in one cart.

Device Sterilization Package

CleanZone SanitationEarthWalk utilizes ozone technology to safely and efficiently kill germs, viruses and bacteria on all devices inside the cart. Decontamination is a quick cycle and there is no chemical residue: Ozone dissipates back to oxygen. Can fully sterilize up to 40 devices more efficiently than UV or chlorine/chemicals.

Integrated Network Systems

Integrated Wireless Packages
EarthWalk carts can be custom configured to integrate additional wireless access points or router systems. This system can provide complete wireless access or help enhance your existing infrastructure by providing additional access as the wireless clients are moved from location to location. The system provides Ethernet uplink to the cart and any required hardwired to wireless switching component. EarthWalk can supply the wireless components or custom integrate any specific or existing electrical components your network may require.

Integrated Hardwired Ethernet Packages
Provide your IT staff with the tools and convenience they need to deploy and support your mobile computer clients. Choose the EarthWalk integrated Ethernet package and deliver remote imaging or software updates to all client machines while they are secured and charging inside the cart.
