DeWalt is a world leading manufacturer in cordless power tools such as power saws, grinders, cordless drills, and impact wrenches. And we would not have practical portable tools without powerful batteries and chargers.

The best chargers on the market are three-stage chargers. And DeWalt makes some of the best three-stage chargers. These units are similar to two-stage chargers except that they allow a slight overvoltage while the charging current drops off, leading to a quicker recharge.

DeWalt uses the Nanophosphate Technology invented by former MIT (The Massachusetts Institute of Technology) engineers that targeted high-power consumers like cordless power tools.

The capabilities of the Nanophosphate system have enabled a new class of Li-Ion battery pack applications. The application of this technology was introduced in DeWalt portable power tools, which established a new level of cordless power tool performance. The Nanophosphate Technology was designed to plow through the toughest applications.

But that is not the only thing DeWalt does to ensure their batteries run at full power for as long as possible. In addition to the Nanophosphate cells DeWalt uses smart charge technology. Each battery pack has a microprocessor which communicates directly with the charger. It makes sure that batteries get fully recharged.

Some other chargers will only accept as much charge as the weakest cell will allow. The DeWalt charger allows charging each cell up to its full potential. So cycle after cycle the battery pack delivers consistent power, longer than the competition.

Each Li-Ion DeWalt battery pack can take up to 2,000 charge-discharge cycles (cycle is each time you use the battery, drain it, and put it back on the charger) and still keep powering your cordless power tools. That is two to three times more than the NiCad or NiMH batteries. Also, DeWalt Li-Ion batteries charge exceptionally quickly and have virtually no self discharge and no memory-effect. They are built to keep their charge longer whether you use them now or a month from now they are ready to go.

DeWalt manufactures many different battery charger models including DW9116 7.2-Volt to 18-Volt Pod Style 1 Hour Battery Charger and DW9118 7.2V - 14.4V 1-Hour Battery Charger. We are going to look specifically at the DC022 Combination 38 Watt Fluorescent Worklight and 7.2-Volt to 18 Volt Dual Port Pod Style Battery Charger with GFCI Protection.

The DeWALT DC022 Fluorescent Worklight is basically two products in one: battery charger and a work light. It uses a 38-watt fluorescent bulb that emits a brighter light than its more common halogen counterparts and far less heat at about the same brightness. Also, it creates whiter and softer light. This DeWalt work light is hugely popular because it is also a duaDeWalt Fluorescent Worklight and Chargerl port charger which can charge any of the DeWalt NiCad batteries between 7.2 and 18v. This worklight/charger can also function as your centre of operations, with power sockets to run three appliances when it is plugged into the mains. Just use one of the three outlets which let you plug directly into the unit. DeWalt designed GFCI protection into these as well.

This unit can really help you out in the work shop or on job site location. This unit is without doubt one of the best chargers on the market, it is available worldwide and provides ultra fast charging of all leading batteries by brand. With the convenience of having battery chargers and power points built, this multipurpose tool becomes more of a portable workstation than a lamp.

It weighs only 10.6 pounds so it is easy to move from job to job.

The DeWALT DC022 comes with a 3-year warranty so you should have no problems getting a replacement if you experience any issues.
