Motorola IMPRES™ 2 Multi-Unit Charger With US Power Supply (PMPN4284B)

(PMPN4284A) IMPRES™ 2 Multi-Unit Charger, w/Power Supply US

Within Motorola’s accessory ecosystem, the PMPN4284B belongs to the IMPRES 2 battery-management platform. Motorola’s IMPRES 2 battery data sheet says IMPRES 2 chargers can charge compatible IMPRES 2 batteries up to 40% faster and support charging customization intended to help manage stored batteries and battery lifecycle more intelligently. That positions the PMPN4284B as more than a simple power accessory; it is part of Motorola’s broader battery optimization system for enterprise radio fleets.

The charger is typically marketed for professional users rather than casual consumers. Motorola’s official accessory page presents it as a fleet-ready fast charger with 1 display, while reseller listings and industrial suppliers identify it as a six-radio / six-battery charger for compatible Motorola product families such as XPR, APX, R5, and R7. That combination makes it especially relevant for public safety support teams, industrial operators, security organizations, schools, transport operators, and facilities departments that need centralized charging instead of individual desktop cradles.

Design and Features

Six-Slot Charging Design

One of the PMPN4284B’s defining features is its six-position charging layout. Motorola’s accessory page says the charger can handle up to 6 radios or batteries simultaneously, which is a core advantage for users managing multiple devices per shift. The single-display layout gives the unit a shared visual interface rather than a separate display per bay, helping balance status visibility with a compact desktop footprint.

IMPRES 2 Charging Technology

Motorola’s IMPRES 2 documentation emphasizes that the charger is part of a smarter battery ecosystem rather than just a power dock. The company states that IMPRES 2 chargers can help improve charging speed and support battery-care workflows, including configurable storage charging behavior. Motorola also notes that IMPRES 2 batteries remain compatible with existing IMPRES chargers, which suggests the PMPN4284B sits within a backward-aware but upgraded charging platform.

One-Display Interface

Motorola’s official accessory page explicitly identifies the PMPN4284 family as a “1 display” charger. While Motorola’s public page does not spell out every on-screen status function line by line, the presence of a built-in display distinguishes this model from simpler multi-unit chargers that rely only on per-pocket LEDs. In operational terms, that makes the PMPN4284B better suited to charging environments where administrators want more centralized status visibility.

Optional Wall Mounting

The charger can also be integrated into more permanent installations. Motorola publishes an official wall mount bracket for the PMPN4284, part number BR000272A01, and accessory listings describe it specifically as the wall-mount solution for the PMPN4284 MOTOTRBO multi-unit charger. This is useful for radio rooms, dispatch areas, security offices, and equipment lockers where desk space is limited or vertical installation is preferred.

Technology and Specifications

Power and Included Supply

Motorola’s shop listing identifies PMPN4284B as a 100–240VAC charger with Power Supply NA, which is the basis for the “with US power supply” product description. The multi-unit charger user guide for the PMPN4283/PMPN4286/PMPN4288 family lists Motorola-authorized power components including the PS000242A01 External 90 W Power Supply and 3087791G01 United States/North America power cord. While the guide refers to the PMPN4283-family kit rather than PMPN4284B by retail suffix, it documents the power architecture used by this charger platform and confirms North American cord support.

Indoor-Use Operating Profile

Motorola’s user guide states clearly that these multi-unit chargers are not suitable for outdoor use and should be used only in dry locations and conditions. It also says the maximum ambient temperature around the charger must not exceed 40 °C (104 °F). These operating conditions matter because they frame the PMPN4284B as a controlled-environment fleet charger intended for indoor radio rooms, service counters, or similar workspaces rather than field deployment.

Device and Battery Charging

The same Motorola user guide says multi-unit chargers will charge authorized batteries when used with the correct pockets, and that the batteries may be attached to a radio or be stand-alone. Motorola’s PMPN4284 product page also says it can charge radios or batteries simultaneously, which confirms dual-use operation for fleet workflows where some users dock full radios while others charge spare batteries only.

Fleet Management and Reprogramming Context

The user guide for the related IMPRES multi-unit charger platform lists reprogramming and fleet management as supported charger functions for the MOTOTRBO professional digital radios series charger family. That is an important clue about how Motorola positions this charger ecosystem: it is not purely about charging, but also about organized fleet administration when used in the right environment and with the right accessories or pockets.

Compatibility

Motorola’s official shop result states that the PMPN4284B is compatible with XPR series radios. Industrial supplier and reseller listings broaden that to common supported families such as APX, R7, R5, and XPR series radios. Grainger’s listing describes it as fitting APX/R7/RM/XPR Series, while another reseller describes compatibility with APX 900, APX 1000, APX 3000, APX 4000, XPR 3000 Series, XPR 6000 Series, XPR 7000 Series, R5, and R7. Because compatibility can depend on the correct charging pocket or insert, buyers should verify the exact radio-and-battery combination before purchase.

Reseller descriptions also note removable pocket inserts, which supports the idea that the same charger base can serve different compatible device families with the correct insert or configuration. That makes the PMPN4284B more flexible for organizations standardizing around one charger chassis while supporting several radio models.

Applications and Use Cases

The PMPN4284B is best suited to environments where multiple radios must be kept charged, staged, and ready for duty. Six-bay charging is especially useful for security teams, schools, facilities departments, hospitals, industrial plants, transportation operators, event venues, and public-safety support units that issue radios by shift or maintain reserve batteries. Motorola’s own product language about charging six radios or batteries at once points directly to this kind of fleet workflow.

It is also valuable in organizations that want to centralize radio charging instead of relying on a collection of single-unit desktop chargers. A shared multi-unit charger reduces cable clutter, simplifies power distribution, and can make battery status easier to oversee from one location. That inference is supported by the charger’s six-slot design, single display, and wall-mount accessory path.

For agencies and enterprises already using IMPRES 2 batteries, the charger adds a battery-management benefit beyond simple recharging. Motorola’s IMPRES 2 data sheet emphasizes faster charging and more flexible battery-care behavior, which can be especially valuable where radios are in constant circulation and battery health directly affects uptime.

Advantages / Benefits

One major advantage of the PMPN4284B is charging density. Instead of deploying six separate chargers, organizations can charge up to six radios or batteries on one multi-unit base. That can improve bench organization and reduce the number of power adapters needed in a radio room.

A second advantage is the IMPRES 2 ecosystem. Motorola says IMPRES 2 chargers can charge compatible IMPRES 2 batteries up to 40% faster and support battery management features beyond ordinary charging. For users already invested in Motorola batteries and radios, that can translate into better battery readiness and potentially more predictable lifecycle management.

A third advantage is installation flexibility. The optional BR000272A01 wall mount bracket gives organizations a way to move the charger off countertops and into structured equipment layouts. This is especially helpful in dispatch, security, and fleet-support environments where space is valuable.

Summary

The Motorola IMPRES™ 2 Multi-Unit Charger With US Power Supply (PMPN4284B) is a fleet-oriented six-slot charger built for organizations that need centralized, professional charging for compatible Motorola radios and batteries. Motorola’s own listings identify it as the current version of the PMPN4284 family, replacing PMPN4284A, and describe it as an IMPRES 2 charger with one display that can charge up to six radios or batteries simultaneously. Combined with Motorola’s IMPRES 2 battery-management ecosystem, North American power configuration, and optional wall-mount support, the PMPN4284B is best understood as a structured charging solution for serious radio operations rather than a simple accessory.

Comparisons

Compared with a single-unit desktop charger, the PMPN4284B is a much more scalable charging solution because it consolidates multiple radios or batteries into one station. Compared with simpler multi-unit chargers, the PMPN4284B stands out for being part of Motorola’s IMPRES 2 platform and for including a display rather than relying solely on bay-level lights.

Compared with the older PMPN4284A naming, Motorola’s current shop listing identifies PMPN4284B as the current part and explicitly notes it was previously PMPN4284A. That means buyers researching either code are generally looking at the same charger family, but the B-suffix is the more current ordering reference in Motorola’s current retail metadata.

Pricing and Availability

Motorola’s current shop category listing shows the PMPN4284B as backordered and priced at $756.92 on the Motorola Solutions shop page at the time surfaced by web search. Third-party reseller pricing varies considerably, with some listings significantly higher and others lower depending on region, stock condition, and included accessories. That makes Motorola’s own shop price a useful benchmark, but not the only market reference.

Because the charger is sold into business and public-sector channels, availability can depend on region, radio-family configuration, and whether the buyer also needs inserts, wall-mount hardware, or specific power-cord localization. It is sensible to confirm the exact package contents, especially since Motorola pages and reseller pages may refer interchangeably to PMPN4284A/PMPN4284B during the transition between part numbers.
