Detailed Teardown and Review: The thinkplus Striker 125W Power Bank – The Ultimate Companion for Your 45W GaN Charger

1. Introduction: The Evolution of Mobile Power in the GaN Era

In the rapidly evolving world of mobile technology, the line between a portable battery and a stationary wall adapter is becoming increasingly blurred. Users today demand versatility, speed, and compactness. Enter the thinkplus Striker High Power Laptop Power Bank 125W, a device that redefines portable energy. While many users are accustomed to carrying a compact 45w gan charger for their daily commute, the need for off-grid power remains critical. This new member of the thinkplus Striker series is designed specifically for travel, mobile offices, and high-demand scenarios like concert photography. It complements your existing charging ecosystem, filling the gap where a standard gan wall charger cannot reach, while offering features that mimic the utility of a three port charger hub.

2. Unboxing and First Impressions: A Sleek, Ergonomic Design

Upon unboxing, the thinkplus Striker reveals a sophisticated silver-gray exterior that exudes professionalism. The packaging includes the power bank, a storage bag, manuals, and a high-quality USB-C to USB-C cable. The cable itself is noteworthy, equipped with an E-Marker chip capable of handling 50V 5A transmission, ensuring it supports the device's massive 125W output. The ergonomic design makes it easy to hold, despite its high capacity. Unlike a stationary gan wall charger, this device is built for movement, yet it integrates a smart dynamic digital display. This screen provides real-time data on battery levels and input/output power, a feature rarely seen even on a high-end three port charger, allowing users to monitor their device's charging status with precision.

3. Interface and Connectivity: The Versatility of a Three Port Charger

The connectivity options on the thinkplus Striker are designed to maximize utility. It features a 2C1A configuration, meaning it has two USB-C ports and one USB-A port. This layout effectively turns the battery into a portable three port charger. Both USB-C ports support a wide array of fast-charging protocols, including PD3.0, PPS, and QC3.0. This ensures compatibility with virtually any device, from lightweight laptops to smartphones and tablets. When you are near an outlet, the device supports pass-through charging. You can plug a 45w gan charger into the input port, and the power bank will distribute power to other devices plugged into it. This "Digital Hybrid" mode transforms the battery into a desktop charging hub, mimicking the functionality of a dedicated gan wall charger while simultaneously replenishing its own cells.

4. Performance Analysis: Input and Output Dynamics

One of the standout features of this power bank is its input capability. It supports up to 45W self-charging. To maximize this efficient recharge speed, pairing it with a reliable 45w gan charger is highly recommended. This ensures the 12800mAh battery can be topped up quickly between meetings or flights. On the output side, the single-port output can reach a staggering 125W, sufficient for high-performance laptops. When multiple ports are used, the intelligent power distribution kicks in. This dynamic allocation is superior to a standard, non-intelligent three port charger, ensuring that connected devices receive the optimal current without overloading the circuit. Whether you are using a gan wall charger to feed it or drawing power from it, the performance remains stable and efficient.

5. Internal Teardown: Structural Integrity and Thermal Management

Disassembling the thinkplus Striker reveals a construction quality that rivals top-tier industrial electronics. The casing is secured with clips and screws, ensuring durability. Inside, a large area of copper foil is used for heat dissipation, a critical component given the high power density. Just as a gan wall charger requires advanced cooling to maintain its compact size, this power bank utilizes thermal paste and thermistors to monitor temperature in real-time. The internal structure uses a "sandwich" design with plastic isolation boards and foam cushioning between the battery pack and the PCB. This robust mechanical design ensures that the device can withstand the rigors of travel better than a typical plastic-shelled three port charger.

6. Battery Technology: Automotive-Grade Power

At the heart of the thinkplus Striker are four 18650 battery cells manufactured by EVE Energy. These are not standard consumer batteries; they are INR18650/33V automotive-grade cells. Each cell boasts a capacity of 3.2Ah and has passed rigorous certifications including CCC and CE. The use of automotive-grade cells ensures higher consistency, safety, and longevity compared to standard batteries found in cheaper alternatives. While a gan wall charger relies on semiconductor efficiency, a power bank relies on chemical stability. The combination of these high-quality cells with the device's ability to act as a three port charger hub makes it a reliable energy storage solution that users can trust on airplanes and in critical work environments.

7. Circuitry and Protection: The Brains Behind the Power

The PCB features the Injoinic IP5389H, a highly integrated System-on-Chip (SoC) designed for high-performance power banks. This chip manages the synchronous buck-boost conversion, allowing the device to handle voltage changes efficiently—similar to the power management found in a premium gan wall charger. The system is further protected by a Chipsea CM1341-DAT lithium protection chip, which offers precision monitoring for over-charge, over-discharge, and short circuits. The presence of multiple low-resistance MOSFETs and high-quality solid capacitors (from Polycap and Dongjia) ensures that the output ripple is minimized. This level of electronic engineering guarantees that whether you are using it as a battery or simulating a three port charger via pass-through, your devices are safe from electrical anomalies.

8. Conclusion: A Must-Have for the Modern Professional

The thinkplus Striker 125W is more than just a battery; it is a comprehensive power solution. Its ability to function as a three port charger for multiple devices, combined with its high-speed input compatible with a 45w gan charger, makes it indispensable. The build quality, evidenced by the automotive-grade EVE cells and advanced Injoinic chipset, sets a high bar for safety and performance. For users who already own a gan wall charger but need that same level of power and multi-port utility on the go, this product is the perfect bridge. It successfully combines the portability of a battery with the versatility of a desktop charging station, ensuring you are never left without power, wherever your work takes you.
