- One AC power supply / line cord (US/NA plug)
Who this product is for
The PMPN4589 is built for organizations that issue Motorola Curve radios to a team and need to recharge a fleet between shifts from one location. Consolidating six radios into a single charger reduces the number of wall outlets, single-unit chargers, and cable runs needed at a charging station or back-office counter.
Common environments include:
- Hospitality — hotels, resorts, and restaurants that hand radios to front-desk, housekeeping, valet, and food-and-beverage staff at the start of each shift.
- Retail and grocery — store teams that share a pool of radios across departments and shift changes.
- Warehousing and logistics — distribution and fulfillment operations charging radios for floor staff and supervisors overnight.
- Education and houses of worship — campuses and facilities that store and recharge a set of radios in a single secure location.
- Events and property management — teams that deploy multiple Curve units per shift and need predictable turnaround between uses.
If your radio count exceeds six, multiple PMPN4589 trays can be deployed side by side, or a single-unit charger can be added for overflow units.

- Covered by a one-year manufacturer replacement warranty.
Frequently asked questions
Which radios are compatible with the Motorola PMPN4589?
The PMPN4589 is designed for Motorola Curve (DLR110 series) license-free digital two-way radios. It charges those radios with their batteries installed, and it can also charge compatible BT90-series batteries. It is not intended for other Motorola radio families such as the CLP, CLS, DTR, or RM series, which use their own chargers.
How many radios can the PMPN4589 charge at the same time?
Six. The unit has six charging pockets and powers all of them from a single AC outlet, so an entire small fleet of Curve radios can recharge from one connection at a charging station.
Can it charge a spare battery on its own, without the radio?
Yes. Each pocket can charge a Curve radio with its battery installed, or a compatible BT90-series battery on its own, which is useful for teams that rotate spare batteries during long shifts.
Does the PMPN4589 include radios or batteries?
No. The kit includes the six-pocket charging base and an AC power supply only. Radios and batteries are purchased separately. The charger is an accessory for Curve radios you already own or buy alongside it.
What is the difference between the PMPN4589 and a single-unit Curve charger?
A single-unit charger services one radio at a time and is suited to personal desk charging. The PMPN4589 services six units from one outlet and is intended for team or fleet charging at a central location. Many organizations use a six-pocket tray for the main fleet and add a single-unit charger for overflow or individual desks.
Is the PMPN4589 the same product as the PMPN4589A?
Yes. PMPN4589 and PMPN4589A refer to the same Motorola six-pocket multi-unit charger for the Curve; the suffix is a catalog variation. Both are genuine Motorola OEM parts.
What warranty comes with the charger?
The PMPN4589 carries a one-year manufacturer replacement warranty. Tech Wholesale has been an authorized Motorola dealer since 1997 and can assist with warranty questions after purchase.
