Kastar 1-Pack Battery and LTD2 USB Charger Compatible with Arlo Pro 4

Our review of the Kastar 1-Pack Battery and LTD2 USB Charger finds it is aimed at Arlo Pro 4 XL and similar camera owners who need a high-capacity spare battery plus a flexible charger. The single biggest reason to buy is convenience: the 13000mAh lithium-ion battery paired with a USB dual charger that accepts Micro-USB or Type-C makes keeping cameras powered for longer simple, whether at home or on the go. For those who run multiple Arlo cameras or need quick swaps, this kit reduces downtime and adds useful LED status feedback during charging.

Key Features

• High capacity battery: The 13000mAh lithium-ion cell delivers extended runtime to reduce how often cameras need recharging or battery swaps.
• Dual battery charger: The LTD2 USB charger can charge two batteries at once, which helps maintain multiple cameras without waiting between charges.
• Flexible input options: Micro-USB and Type-C inputs give multiple charging options and the charger ships with a Micro USB cable for immediate use.
• Portable power design: The charger accepts a 5V 2-3A 15W input so it can be used with common USB power adapters for travel and field work.
• Visible charging status: Intelligent LED indicators show both charging status and relative battery capacity so users can tell when batteries are ready.
• Interchangeable plate: The charger plate can be changed to accommodate different compatible battery types, increasing versatility.

Who It's For

This kit is best for Arlo Pro 4 XL Spotlight 3 Camera owners and anyone running multiple compatible Arlo cameras who wants a high-capacity spare battery and the ability to charge two batteries simultaneously. It suits installers, homeowners with several cameras, and users who prefer swapping batteries instead of hard wiring or recharging cameras in place.

It is less suitable for users who need factory-original batteries for warranty reasons or who only power a single camera and never need extra runtime, since a single spare battery and simple single-slot charger might be enough for those users.

Pros & Cons

Pros

• Large 13000mAh capacity provides long runtime between charges for Arlo-compatible models.
• Charger can power two batteries simultaneously, saving time when multiple spares are used.
• Micro-USB and Type-C inputs plus included Micro USB cable increase compatibility with common power sources.
• LED indicators clearly show charging progress and battery capacity for easier workflow.

Cons

• The battery and charger are third-party parts, so users seeking only manufacturer-original components should consider that before purchasing.
• The review notes the charger output is limited to 800mA per slot, which means full charging can take longer compared with higher-current proprietary chargers.
