What problem does this charging kit solve?

The Streamlight 18650 Dual Input Charging Kit directly tackles several common pain points associated with high-performance rechargeable batteries:

• Lack of Charging Versatility: Many chargers are limited to a single power source. This kit's dual input capability ensures you can charge virtually anywhere.
• Slow or Inefficient Charging: Optimized charging profiles ensure quick turnaround times, minimizing downtime for your essential gear.
• Battery Degradation & Safety Concerns: Generic or poorly designed chargers can damage batteries or pose safety risks. Streamlight's integrated safety features and robust battery design protect your investment.
• Downtime & Unpreparedness: Dead batteries lead to device failure when it matters most. This kit keeps your power sources topped up and ready.
• Cost of Disposable Batteries: Investing in a reliable rechargeable system like this significantly reduces the long-term cost and environmental impact of disposable batteries.

Deep Dive into the Streamlight Charging Cradle & 18650 Lithium Ion Batteries

The heart of this system is the dual-bay charging cradle, paired with two high-quality Streamlight 18650 button-top lithium-ion batteries. Each component is engineered for performance, durability, and user convenience.

Unmatched Charging Flexibility with Dual Input Design

One of the most compelling features of the Streamlight charging cradle is its dual input capability. Unlike many chargers that force you to rely on a single power source, this cradle offers unparalleled adaptability:

• 5V Micro-USB Input: This ubiquitous standard allows you to charge your 18650 batteries from a vast array of sources. Think power banks, computer USB ports, vehicle USB adapters, or any standard USB wall adapter. This is invaluable for on-the-go charging or when traditional wall outlets are unavailable. The custom locking feature for the micro-USB input ensures a secure connection, preventing accidental disconnections in active environments.
• Streamlight "Traditional" AC or 12V DC Power Sources: For reliable, consistent power, the cradle also accepts Streamlight's dedicated AC wall adapters or 12V DC vehicle adapters. This ensures you have a robust charging option whether you're at home, in the office, or out in the field using your vehicle's power.

This dual input design provides critical redundancy, meaning you're never left without a way to recharge your batteries, no matter where your mission or adventure takes you.

Simultaneous Charging for Maximum Efficiency

The charging cradle is intelligently designed to accommodate either a single 18650 battery or two batteries concurrently. This dual-bay functionality significantly enhances efficiency, allowing you to prepare backup batteries while your primary device is in use, or to quickly charge two batteries overnight. Each bay operates independently, with dedicated charge status indicators, ensuring optimal charging for each battery inserted.

Optimized Charging Times for Rapid Readiness

Speed and efficiency are paramount. The Streamlight charging cradle is engineered to provide impressive charge times:

• Single Bay Charging: When charging a single 18650 battery in either bay, a full charge is achieved in approximately 3.5 hours. This rapid turnaround ensures your essential tools are quickly back in service.
• Both Bays Charging: If charging two batteries simultaneously, the left bay (designated as the priority bay) will also achieve a full charge in 3.5 hours. The right bay, managing its charge cycle concurrently, will reach full capacity in approximately 6.5 hours. This intelligent prioritization ensures your most critical battery is ready sooner, while still efficiently managing the second battery.

These optimized charge times mean less waiting and more doing, a crucial factor for professionals and enthusiasts alike.

Robust and Durable Construction

Built to withstand the rigors of demanding use, the charging cradle features impact-resistant polymer construction. This durable material ensures longevity and resilience against drops, bumps, and general wear and tear in various environments, from a tactical pack to a workshop bench. Its solid build quality reflects Streamlight's commitment to reliability in all its products.

The Power Within: Streamlight 18650 Lithium-Ion Batteries

The kit includes Streamlight's high-quality 18650 button-top lithium-ion batteries, which are far from generic cells. These batteries incorporate an on-board safety control circuit, a critical feature that protects against common battery issues such as:

• Overcharge Protection: Prevents the battery from being charged beyond its safe voltage limit, which can cause overheating and damage.
• Over-discharge Protection: Stops the battery from being drained too low, which can permanently damage the cell and reduce its lifespan.
• Short-circuit Protection: Automatically cuts off power in the event of a short circuit, preventing dangerous heat buildup or fire.
• Temperature Protection: Monitors battery temperature during charging and discharging, adjusting parameters to prevent overheating.

This integrated safety circuit not only extends the overall lifespan of the battery but also provides essential peace of mind for the user. With a remarkable capacity for up to 500 recharge cycles, these batteries offer exceptional long-term value and reduced waste compared to disposable alternatives.

Intuitive User Experience with Individual Bay LEDs

To keep you informed at a glance, the charging cradle features individual LED indicators for each bay. These LEDs clearly display the charging status of each battery, letting you know when a battery is charging, nearing completion, or fully charged. This simple yet effective visual feedback eliminates guesswork, allowing you to manage your power resources more effectively.

Compact and Portable Design

Both the charger and batteries are designed with portability in mind:

• Charger Dimensions: Measuring a compact 4.5 inches (11.4 cm) and weighing just 2.4 ounces (68 grams), the charging cradle is incredibly easy to pack and transport, whether in a gear bag, backpack, or glove compartment.
• Battery Dimensions: Each 18650 battery is 2.75 inches (7.0 cm) long and weighs 1.7 ounces (48 grams), making them lightweight and easy to carry as spares.

This compact footprint ensures that dependable power is always within reach, without adding unnecessary bulk to your essential gear.
