Kastar 2-Pack Battery and LTD2 USB Charger Compatible with Arlo A-2

In this review the Kastar 2-Pack Battery and LTD2 USB Charger is evaluated for owners of Arlo Go and compatible Arlo A-2 battery cameras. The bottom line: this kit is for users who need reliable spare power and a flexible dual charging option. It stands out because the charger can charge two batteries at once, offers both Micro-USB and Type-C input options, and the batteries themselves provide a high 4800mAh capacity at 7.2V that extends camera runtime. For anyone who relies on Arlo Go or listed A-2 batteries, this is a practical power solution.

Key Features

• High capacity batteries: Each Lithium-Ion 4800mAh battery delivers extended runtime for Arlo Go and compatible cameras so users spend less time swapping cells.
• Dual-charge convenience: The LTD2 charger can charge two batteries simultaneously, which speeds turnaround for multi-battery setups.
• Interchangeable charging plate: The charger lets you change the plate to accommodate different battery contacts, increasing compatibility with listed Arlo battery models.
• USB power input: With 5V 2-3A input and both Micro-USB and Type-C options, the charger works with common power packs and adapters for flexible charging on the go.
• Intelligent LED indicators: The charger shows charging status and approximate battery capacity via LEDs, making it easy to see when cells are ready.
• Portable design: The compact pack and included Micro-USB cable make it straightforward to carry replacement power for remote camera installations.

Who It's For

The Kastar kit is aimed at Arlo Go owners or anyone using Arlo A-2 series batteries who need spare batteries and a compact dual charger. It is especially useful for field deployments, temporary installations, or users who want to keep rotation batteries charged and ready.

Users who require official-brand batteries for warranty or certified parts should look elsewhere; similarly, those who need very fast high-current charging for non-camera devices should consider more powerful dedicated chargers. This kit is optimized for camera backup power and convenience rather than fast charging of other electronics.

Pros & Cons

Pros

• High 4800mAh capacity batteries extend camera runtime between swaps.
• Can charge two batteries at the same time, reducing downtime for multi-battery users.
• Includes Micro-USB cable and supports Type-C input for flexible charging options.
• LED indicator lights provide clear charging status and capacity feedback.

Cons
