Bosch Power Ready Wireless Charging System

How did we ever get by without cordless power tools?  Many younger skilled carpenters and construction workers have never had to. However, most veterans contractors have had to deal with power cords and pneumatic air hoses.

Did you know that the increase in cordless tools has decreased the amount of workman’s comp trip and fall and shock claims due to cord?  Besides eliminating cords, compressors and other accessories, cordless tools are now stronger, more powerful and have significantly increased run-times that make them a viable work-site tool.

Improvements in Cordless Lead to Bosch Wireless Charging:

Brush-less tools, advanced electronics and battery technology are the driving factors in today’s cordless tools.  Cordless tool battery chargers “read” the battery and optimizes its charge based on the information it receives, improving battery performance and longevity.

Cordless battery technology as gone from lead-acid, nickel-cadmium batteries, which created environmental concerns, to the alternative, “memory effect,” nickel-metal hydride battery, and now lithium-ion batteries.

Lithium-ion batteries deliver an exceptional amount of power in a much lighter package and suffer no memory effect.   Batteries are now capable of handling applications with higher current draws, making it more feasible to use cordless tools in demanding industrial and construction workplaces.

That brings us to the Bosch wireless charging system.   This new charging system allows users to recharge a tool anytime it would otherwise rest idle, eliminating downtime and dead batteries.

The Bosch wireless charging system components include:

  • Wireless charger
  • Docking frame
  • Wireless-compatible 2.0 Ah 18V Li-ion battery pack

The new battery is compatible with all Bosch 18V power tools and only can be charged on the new wireless charger.   A mountable holster will be available shortly and promote a grab and go storage solution.  [photos of holster are included in this article]

Bosch Solution to a Job-Site Problem

The  Bosch wireless charging system is perfect for the mobile contractor who depends on finding electrical power on each job-site to charge tools.   This system provides them with an in-vehicle charging system that works.  The batteries are 80% charged in 30 minutes and 100% charged in 50 minutes.   They can charge while traveling from job to job.   It’s not just for the mobile solution, it will also work equally well for mechanics, in work-shops and manufacturing plants for folks who lose track of where they left their tool or spare batteries and cluttered charging stations take up space with batteries all over.

The Bosch wireless charging system improves productivity and ensures that you will always have a fully charged battery and works in the following area:

  • Truck / Trailer / Van
  • Job Box Charging Station
  • Cart mounting

Bosch Wireless Benefits:

  • Innovative solution to the core problem of dead batteries
  • Eliminates the need for a bin of batteries with a partial charges
  • Easily charge hand-held power tools in between tasks or jobs
  • Increased productivity
  • Compatible with complete Bosch 18V power tools
  • Features Foreign Object Detection

How It Works

The charger woks on the concept called inductive charging, similar to a modern, Phillips Sonocare rechargeable toothbrush. When the charger is plugged in and the compatible battery is placed on it, the charger begins wireless transmission through an alternating magnetic field.

The battery, featuring an internal copper coil, acts as a receiver. As the alternating magnetic field penetrates the coil, voltage is induced and a charging current flows to the cells until full.   all this is done with minimal to no extreme heat transfer.  The charger also features Foreign Object Detection, which detects when any other object [metal washer, screw or nail] besides the compatible battery is on the charging pad. If sensed, the charger will not turn on until the object is removed.

We tested this on our model and the Foreign Object Detection worked perfectly!!

NEW Bosch Mobile Holster:

The mobile holster, which we feel is a bit bulky,  seems like it will be a more secure way to charge your tool.   The holster can be wall- or shelf-mount the charger with either the WC18H mobile tool holster or WC18F charger frame.  Bosch says that this holster takes up half the space of a case but the problem with this argument is that the tool case allows you to store tool drill / impact ready bits and accessories.

 Bosch Wireless Charging System Kits:


  1. WCBAT612  -is a SlimPack 18V 2.0 Ah battery.  4.0 ah batteries are planned for next year.
  2. WC18C – The WC18C Wireless Charger will charge the WCBAT612 80 percent in approximately 30 minutes and 100 percent in 50 minutes (from empty). It features charge status indicator lights for easy recognition.
  3. WC18F – Available with all Bosch Power Ready Wireless Charging System kits, the WC18F frame is designed to mount the charger to workbenches, shelves, side walls or other work surfaces, and serves as a flexible and secure holder for the battery or tool and battery (on horizontal surface).
  4. WC18H – The Bosch WC18H Mobile Holster offers users the industry’s first customized charging and storage system. Easily mounts to any shelf or side wall for quick and convenient tool charging and storage.

12 Volt Charging Options:

Currently this wireless system is only offered in a 120 volt configuration and if mounted in a vehicle will need an inverter.   A 12 volt power cord with an auxiliary charger is coming out next year

Where Do We Go From Here?

It is not surprising that a cordless tool batteries makes up about 50 percent of the total cost of a cordless tool system.

Battery technology will not stop at lithium as manufacturers  continue to develop new chemistries that are more durable and efficient. As we’ve seen with the introduction of a 5.0 Ah battery, and this wireless system, battery capacity will continue to increase, expanding amp-hours,  while decreasing weight and size.

Bosch has a huge road-map ahead of them – this is just the beginning.  Where do they go from here?   L-Boxx chargers while your tools are on a shelf and being stored?   Concord Carpenter predicts that the next range of battery improvements will be around decreasing charge times,  and maybe even eliminating the need for chargers altogether.

How Much and Where to Buy?

The Bosch WC18CF-102 18-Volt Wireless Charging Starter Kit with 18-Volt Wireless Charger, Frame and 18-Volt 2.0 Ah Wireless Battery sells online for $ 159.00 here: Bosch-WC18CF-102-18-Volt-Wireless-Charging
