FLEX "CA SP 2× 12/18" Dual Charger (12/18V) 1 Stück

FLEX CA SP 2× 12/18 Dual Charger — Charge Two Batteries Simultaneously with 2×150W

What is the FLEX CA SP 2× 12/18 Dual Charger? The FLEX CA SP 2× 12/18 is a dual fast charger with two independent charging slots that simultaneously charges FLEX 12V and 18V battery packs at 6A each (2×150W) — including battery cooling, LED status display, and STACK PACK compatibility for stationary workshop use.

Anyone working professionally with the FLEX battery system knows the problem: one charger, one battery, one waiting period. The FLEX CA SP 2× 12/18 Dual Charger solves this problem with a simple approach — charge two batteries simultaneously, independently, each with a full 6A charging current per channel. No halving of charging power in dual operation, no prioritization of one channel at the expense of the other: both batteries charge at full speed.

The CA SP 2× 12/18 is the most powerful charger in the FLEX Detailing portfolio and is aimed at professional users who work with multiple batteries daily — be it with the PXE 80 12-EC, the 18V polishers, or the BW 18.0-EC Cordless Blower. The device charges all current FLEX 12V and 18V battery packs and can be used across systems — a single charger for the entire FLEX portfolio.

STACK PACK compatibility also makes the CA SP 2× 12/18 an ideal component of an organized workshop setup. Wall mounting, cable winding on the housing, robust plastic housing — everything about this device is designed for continuous, professional use. As a cross-system charger for the entire FLEX portfolio from 12V to 18V, it is the only charger you really need — if you are willing to make the necessary investment.

• Two channels, 150W each — true simultaneous operation without compromise. The CA SP 2× 12/18 uses two fully independent charging circuits, each with 150W of power. This means: Channel 1 and Channel 2 both charge with a full 6A charging current, regardless of what is in the other channel. No sharing of total power, no sequential operation. Two 5.0 Ah batteries charged simultaneously in 60 minutes each — that's true simultaneous operation.
• 12V and 18V in one device — the only charger for the entire FLEX system. The CA SP 2× 12/18 charges all FLEX battery packs from 12V to 18V. So, if you use both the AP 12V for the PXE 80 and an 18V battery for the XFE 2 15 18-EC, you only need one charger — and it charges both simultaneously. This reduces the number of devices in the workshop and maximizes charging efficiency.
• Integrated battery cooling for continuous operation and battery protection. The active cooling in the CA SP 2× 12/18 keeps the batteries within the optimal temperature range during charging. Lithium-ion cells lose capacity faster when hot; a battery that comes hot out of the machine after heavy use and is immediately charged benefits significantly from active cooling. For detailers who run their batteries multiple times a day until they are discharged, this is a crucial factor for the longevity of the cells.

Practical Tip from Detailing1: In professional operation with PXE 80 (12V) and XFE 2 15 (18V) used in parallel, many detailers use the CA SP 2× 12/18 as a central charging station: the left side charges the 12V PXE battery, the right side charges the 18V polisher battery — while both machines are in use with their respective charged batteries. The result: no charging interruptions, no waiting, maximum throughput in vehicle preparation.

2×150W Simultaneous Charging — How the FLEX CA SP 2× 12/18 Charges Two Batteries in Parallel

The technical core of the CA SP 2× 12/18 lies in its dual-circuit architecture. Each of the two channels has its own charging electronics with 150W of power and 6A of charging current. When both channels are occupied simultaneously, they operate completely independently — neither channel "knows" about the other, no algorithm has to divide power between them.

This sounds obvious, but it isn't. Many cheaper dual chargers on the market share a common power supply capacity between two outputs. In simultaneous operation, this means: halved charging power per channel, extended charging times. A 5.0 Ah battery then charges not in 60 minutes, but in over two hours — the supposed advantage of the dual charger is negated. So, if you don't pay attention to this detail when buying a dual charger, you might end up with a more expensive device with a worse result than two cheap single chargers.

The CA SP 2× 12/18 delivers 2×150W of power for true simultaneous operation. The charging times in dual operation are identical to those in single operation: 40 minutes for the 2.5 Ah battery, 60 minutes for the 5.0 Ah battery, and 95 minutes for the 8.0 Ah battery — on both channels simultaneously. This is the decisive buying argument for professional users who consider charging times a limiting factor in their workflow.

The total weight of 1.89 kg and dimensions of 310×278×85mm make the CA SP a compact device that, despite its dual charging capacity, takes up hardly more space on the workshop shelf than a single standard charger. Cable management with integrated cable winding on the housing keeps the workplace tidy.

Charging Times in the CA SP 2× 12/18 — 12V and 18V Batteries at a Glance

The CA SP 2× 12/18 charges all current FLEX battery packs from 12V to 18V. Charging times for the 18V battery packs are directly available:

The FLEX AP 18V 2.5 Ah is fully charged in approx. 40 minutes — which corresponds to the time window between two polishing units on a vehicle. The 5.0 Ah battery is ready for use in about 60 minutes, and the powerful 8.0 Ah battery (XLITHIUM) in about 95 minutes. In continuous operation with three or more 18V batteries in rotation, a virtually uninterrupted workflow results, as the charging time of one battery corresponds to the operating time of the others.

For the 12V battery packs — AP 12V in 2.5 Ah or 5.0 Ah — comparable charging times of 40 to 50 minutes apply, thanks to the full 6A charging current on both channels. In mixed operation (12V on one channel, 18V on the other), each channel maintains its full charging power — the charger automatically detects the connected battery voltage and selects the appropriate charging profile.

The integrated LED status display shows the charge status independently for each channel: charging process active, charging process completed, or error. With multiple charging processes running in parallel, you always keep an overview without complex checking. A quick glance at the device is enough to know which battery is ready and which still needs a few minutes — important in time-critical operations when the next customer order is waiting.

The active battery cooling in the CA SP 2× 12/18 also distinguishes this device from simpler chargers. If a battery is hot in the charger after intensive use, the integrated system cools it down to the optimal charging temperature before the actual charging process begins. This extends the charging time by a few minutes but protects the cells from the feared "hot-charging" — one of the most common reasons for premature capacity loss in lithium-ion batteries in continuous operation.

STACK PACK Compatibility and Workshop Integration of the CA SP 2× 12/18

A detail that goes beyond the pure charging process: The CA SP 2× 12/18 is compatible with the FLEX STACK PACK storage system. This means it can be mounted directly on the lid of STACK PACK boxes or integrated into the stacking system — for professional detailers who organize all their FLEX equipment in the STACK PACK system.

Wall mounting is also provided. Mounted on the workshop wall, the CA SP 2× 12/18 becomes a permanent charging station that always keeps two batteries ready. Together with the cable winding on the housing, this creates a tidy, professional setup without cable clutter and without searching for chargers or cables.

For detailers who work at events or on customer sites, the CA SP can also be used mobile. At 1.89 kg, it is heavier than the CA 12 or CA 12/18, but for the transport weight, it delivers the charging capacity of two separate chargers. One device instead of two — less transport weight, less cable clutter, less setup effort on site. Especially at car detailing events, where power outlets are scarce, a charger with two outputs is a real advantage: one connection, double the charging capacity.

Those who organize their FLEX setup in the STACK PACK system will find the CA SP 2× 12/18 a device that is seamlessly integrated into this system world. Wall mounting on the STACK PACK base plate or the lid of a box enables a permanently installed charging station that remains portable at the same time. This makes the CA SP a central element of a professional, mobile detailing setup.

CA SP 2× 12/18 Compared to CA 12 and CA 12/18 — Which Charger for Which Need

FLEX offers three relevant chargers for the detailing portfolio, which are clearly distinguished by their target group.

The CA 12 230/CEE is the focused 12V single charger with 5A — compact, affordable, ideal for beginners in the PXE 80 system or as a second device for wall mounting. If you only operate a 12V polisher and do not plan for 18V devices, you don't need more.

The CA 12/18 230/CEE charges 12V and 18V single batteries, offers LCD battery diagnostics and 9A charging current — the standard charger for FLEX system mixers with one battery per charging cycle and slightly faster charging speed.

The CA SP 2× 12/18 is the device for professional users with multiple batteries in rotation. The decisive advantage: true simultaneous charging of two batteries without power sharing. Those who charge two or more batteries daily will amortize the extra cost compared to two single chargers through time savings and space savings. As the only device that can charge the entire FLEX battery fleet in one go, the CA SP 2× 12/18 is the most efficient solution for professional continuous operation.

Buying the FLEX CA SP 2× 12/18 — Who Benefits from the Dual Charger?

The FLEX CA SP 2× 12/18 Dual Charger is the right choice for professional detailers who work with two or more batteries and do not want to accept charging times as a workflow interruption. This is especially true for users who use both 12V and 18V FLEX devices and are looking for a single charger for the entire portfolio.

The investment quickly pays off: Two separate chargers — a CA 12 and a CA 12/18 — together cost more than the CA SP 2× 12/18, occupy two power outlets, and require twice as much footprint. The CA SP combines both charging slots in one housing, delivers 2×150W of true simultaneous power, and costs significantly less in proportion than two individual devices.

For the P-Set 22 Q or the P-Set 55 R with multiple 18V batteries, the CA SP 2× 12/18 is the ideal complementary charger: The bundled chargers are supplemented by the dual charger, and the entire battery stock charges in a fraction of the time. Those who push their FLEX system to high operation — multiple vehicles, multiple machines in parallel daily — can hardly do without this charger.
