Kastar 3-Pack Battery and LTD2 USB Charger - Extended Power for Arlo

In this review the Kastar 3-Pack Battery and LTD2 USB Charger is examined for users who need reliable, repeatable power for Arlo XL cameras. The bottom line: this kit is for people who want long runtime and flexible charging options without relying on a single proprietary charger. The reviewer found the giant 13000mAh lithium-ion cells and a dual-port charger with both Micro-USB and Type-C inputs deliver practical, everyday value for home security setups that need spare batteries on hand.

Key Features

• High capacity battery: The 13000mAh lithium-ion cells provide extended run time so cameras stay on longer between swaps.
• Dual battery charging: The LTD2 charger can charge two batteries simultaneously, which speeds rotation when multiple cameras need fresh power.
• Flexible inputs: Micro-USB and Type-C inputs allow charging from common 5V 2-3A power sources for convenience.
• Intelligent LED display: The charger shows charging status and estimated battery capacity so you know when a cell is ready to use.
• Changeable charging plate: The charger plate can be swapped to accommodate different battery contact layouts, increasing compatibility.

Who It's For

This kit suits homeowners and small business owners who run Arlo XL and Pro 4 XL Spotlight 3 cameras and want spare batteries for uninterrupted coverage. It is especially useful for installations where removing a camera to recharge is inconvenient and keeping premade charged replacements onsite is preferred.

Those who should look elsewhere include users who require strictly OEM batteries specified by their camera maker or who need a wall-mounted continuous power option; this product is aimed at removable battery workflows rather than permanent hardwired power solutions.

Pros & Cons

Pros

• High 13000mAh capacity offers long runtimes between swaps for less maintenance.

Cons

• The batteries are large and intended for removable use, so they are not a substitute for dedicated wired power installations.
• Compatibility requires checking supported Arlo battery and camera models before purchase to ensure fit.
