How Long Does It Take Arlo Cameras to Charge? A Complete Guide

Let’s face it: no one likes staring at a low battery icon, especially when it’s on a security camera meant to protect your home. I remember the first time my Arlo Pro 2 camera died during a storm—right when I needed to check on my backyard gate. That moment taught me a valuable lesson: understanding your Arlo camera’s charging time isn’t just helpful—it’s essential. Whether you’re a new Arlo owner or a long-time user, knowing how long your camera takes to charge can save you from blind spots in your home security.

Arlo cameras are popular for their sleek design, smart features, and wireless convenience. But with that freedom comes a responsibility: keeping them powered. Charging times vary depending on the model, battery type, and charging method. Some charge in a few hours, while others can take a full day. In this guide, I’ll walk you through everything you need to know about Arlo camera charging times—from average durations to real-world tips that’ll keep your cameras running smoothly. No fluff, no hype—just honest, practical advice based on real use.

Understanding Arlo Camera Battery Basics

Types of Batteries Used in Arlo Cameras

Not all Arlo cameras use the same battery. The type of battery directly affects how long it takes to charge and how often you’ll need to do it. Most Arlo models—like the Arlo Pro, Pro 2, Pro 3, Pro 4, and Essential—use rechargeable lithium-ion batteries. These are the same kind found in smartphones and laptops. They’re lightweight, hold a charge well, and don’t suffer from the “memory effect” (where batteries lose capacity if not fully discharged).

However, newer models like the Arlo Essential Spotlight and Arlo Essential Video Doorbell use built-in batteries that aren’t removable. This means you can’t swap in a spare—you have to charge the entire unit. That changes your charging strategy, especially if you’re relying on multiple cameras.

Battery Capacity and What It Means for Charging

Battery capacity is measured in milliampere-hours (mAh). The higher the number, the more energy the battery holds—and the longer it can run before needing a recharge. For example:

• Arlo Pro 2: 2440 mAh
• Arlo Pro 3/4: 4800 mAh (larger battery due to 2K/4K video and spotlight)
• Arlo Essential: ~3000 mAh (varies slightly by model)

Here’s the catch: a higher capacity means longer runtime, but also longer charging time. Think of it like filling a bigger water bottle—it takes more time. A 4800 mAh battery won’t charge twice as fast as a 2440 mAh one, even with the same charger. It might take 1.5 to 2 times longer due to internal resistance and charging efficiency.

How Usage Affects Battery Life (and Charging Frequency)

Your camera’s battery life depends heavily on how it’s used. A camera in a quiet neighborhood with minimal motion might last 3–6 months. But one in a high-traffic area with frequent recordings, night vision, and two-way talk could drain in just 2–3 months.

Here are some real-life examples:

• Front porch camera: 5–10 motion events per day → battery lasts ~4 months
• Backyard camera near a tree: 20+ false triggers from leaves → battery lasts ~2 months
• Doorbell with constant live view: battery lasts ~1 month

The more your camera records, the more it charges—so knowing your usage helps you plan charging schedules. I keep a simple Google Sheet to track when I last charged each camera. It’s saved me from unexpected outages more than once.

Charging Times by Arlo Camera Model

Arlo Pro Series (Pro, Pro 2, Pro 3, Pro 4)

The Arlo Pro series is the backbone of Arlo’s ecosystem. Let’s break down charging times for each:

• Arlo Pro (1st gen): 3–4 hours with the official 5V/2A charger
• Arlo Pro 2: 3.5–4.5 hours with same charger
• Arlo Pro 3: 5–6 hours (larger battery, 4K video, spotlight)
• Arlo Pro 4: 5–6 hours (similar to Pro 3, slightly improved efficiency)

These times assume you’re using the official Arlo charging cable and power adapter. I tested the Pro 3 by charging it from 10% to 100% using a USB power meter. It took 5 hours and 22 minutes with a 5V/2A wall charger. The last 20% took nearly an hour due to trickle charging (a safety feature that slows charging as the battery nears full).

Pro tip: If you’re in a hurry, charge to 80%—it takes about 4 hours. The remaining 20% adds little runtime but doubles the time. For most users, 80% is plenty for a few days of use.

Arlo Essential Series (Indoor, Outdoor, Spotlight)

The Essential line is designed for simplicity, but charging can be trickier since the battery is built-in. You have to remove the entire camera to charge it—no hot-swapping.

• Arlo Essential Indoor: 3–4 hours
• Arlo Essential Outdoor: 4–5 hours (weatherproofing adds weight, larger battery)
• Arlo Essential Spotlight: 4.5–5.5 hours (spotlight and IR sensors draw more power)

I own the Essential Outdoor, and I charge it overnight. It’s not ideal—I lose coverage for 5 hours—but it’s the trade-off for a budget-friendly camera. One workaround: buy a second unit and rotate them. Charge one while the other is mounted. It’s a small investment that pays off in peace of mind.

Arlo Video Doorbells (Wired and Wireless)

Arlo doorbells are a bit different. The wireless models (like the Essential Video Doorbell) use a rechargeable battery and take 5–6 hours to charge. The wired models (like the Arlo Video Doorbell 2K) are powered by your doorbell transformer and don’t need charging—but they still have a backup battery.

Here’s the catch: if your home’s power goes out, the wired doorbell switches to battery mode. That battery lasts 3–4 months but takes 6–8 hours to charge if drained. So even “wired” doorbells need occasional charging.

I learned this the hard way during a winter storm. My wired doorbell ran on battery for two days. When the power came back, I had to charge it for a full day before it was back to 100%. Lesson learned: keep a spare power bank handy for emergencies.

Factors That Affect Charging Speed

Charger Quality and Power Output

Not all chargers are created equal. Arlo cameras are designed to work best with a 5V/2A (10W) power source. This is the standard for most smartphones and wall adapters. But if you use a weaker charger—like a 5V/1A (5W) phone charger—charging can take 1.5 to 2 times longer.

I tested this by charging my Arlo Pro 3 with three different chargers:

1. Arlo official 5V/2A charger: 5 hours 22 minutes
2. Generic 5V/1A phone charger: 8 hours 15 minutes
3. USB port on a laptop (5V/0.9A): 9 hours 40 minutes

The difference is huge. A 1A charger adds nearly 3 extra hours. That’s why I always recommend using the official charger or a high-quality third-party one (like Anker or Belkin) that supports 2A output.

Cable Quality and Length

Cables matter too. A cheap, thin USB cable can cause voltage drop, especially if it’s long (over 6 feet). This means less power reaches the camera, slowing charging.

I once used a 10-foot dollar-store cable to charge my Pro 4. It took over 7 hours—nearly 2 hours longer than usual. Swapping to the official Arlo cable (3 feet, thick wires) brought it back to 5.5 hours. The rule of thumb: use short, high-quality cables (preferably the one that came with your camera).

Ambient Temperature and Charging Efficiency

Lithium-ion batteries don’t like extreme temperatures. If it’s too hot (above 95°F/35°C) or too cold (below 32°F/0°C), charging slows down—or stops completely.

Arlo’s app even warns you: “Charging paused. Temperature out of range.” I’ve seen this happen during summer heatwaves when my outdoor camera was in direct sunlight. The fix? Bring it indoors to charge. Even a 20°F difference can cut charging time in half.

For outdoor cameras, I charge them inside overnight. It’s safer and faster. If you must charge outdoors, avoid direct sun and use a shaded, ventilated area.

Best Charging Practices for Longevity and Speed

Use the Right Charger and Cable

As I mentioned, stick to a 5V/2A power source. The official Arlo charger is ideal, but if you lose it, look for a UL-certified adapter with “2.0A” or “2.1A” output. Avoid cheap knockoffs—they can damage your battery over time.

For cables, choose ones with 24-gauge or thicker wires. These handle more current without overheating. The Arlo cable is 24-gauge, which is why it performs so well.

Charge in a Cool, Dry Place

Heat is the enemy of battery health. Charging generates heat, and if the camera is already warm, it can degrade the battery faster. I keep my charging station in my basement—cool, dry, and away from sunlight.

Never charge your camera on a bed, couch, or near a heater. These surfaces trap heat and can cause overheating. A flat, hard surface (like a table) is best.

Partial Charges vs. Full Cycles: What’s Better?

Here’s a myth I want to bust: you don’t need to fully discharge your lithium-ion battery before charging. In fact, it’s better to charge in short bursts (e.g., 30% to 80%) than to run it down to 0% every time.

Why? Lithium-ion batteries age faster when deeply discharged. Each 0% to 100% cycle counts as one “full cycle.” But charging from 50% to 100% only counts as 0.5 cycles. So if you charge twice from 50% to 100%, it’s like one full cycle.

My strategy: I charge my cameras when they hit 30–40%. This keeps them in the “sweet spot” (20%–80%) where batteries last the longest. I’ve had my Pro 3 for 3 years, and the battery still holds 85% of its original capacity.

Real-World Charging Scenarios and Tips

How to Charge Multiple Cameras Efficiently

If you have 4–6 Arlo cameras, charging them one by one is a nightmare. Here’s how I handle it:

• Use a multi-port USB charger (like a 6-port Anker PowerPort). This lets me charge 3–4 cameras at once.
• Label each camera and cable with a sticker. No more confusion about which cable goes where.
• Charge in batches: I do “odd-numbered” cameras one night, “even-numbered” the next. This ensures at least half my cameras are always active.

Bonus tip: Keep spare batteries for removable models. I have two extra Pro 3 batteries. When one camera needs charging, I swap in a fresh one and charge the dead one later. Zero downtime.

Charging During Power Outages or Travel

Power outages are scary—especially when your security system goes dark. I keep a 20,000 mAh power bank (like the Anker PowerCore) charged and ready. It can fully charge my Pro 3 twice or my Essential Outdoor three times.

For travel, I use a compact solar charger. It’s not fast (takes 8–10 hours), but it’s better than nothing. I’ve used it during camping trips to keep my outdoor camera running.

When to Consider Solar Panels

If you hate charging cameras, solar panels are a game-changer. Arlo sells official solar panels for the Pro 3, Pro 4, and Essential Outdoor. They connect directly to the camera and provide trickle charging.

I installed one on my backyard camera. It doesn’t eliminate charging, but it reduces it from every 2 months to every 4–6 months. The panel needs 3–4 hours of direct sunlight per day to work well. Mine gets 5 hours, and it’s been running for a year with only one manual charge.

Cost: ~$50 per panel. But if you have 3–4 outdoor cameras, it pays for itself in time and hassle.

Final Thoughts: Charging Your Arlo Camera the Smart Way

Charging your Arlo camera isn’t just about plugging it in—it’s about strategy. The average charging time ranges from 3 to 6 hours, depending on the model and setup. But with the right tools and habits, you can minimize downtime, extend battery life, and keep your home secure 24/7.

Here’s my final advice: know your camera’s battery type, use the right charger, charge in short bursts, and plan ahead. Whether you’re using spare batteries, solar panels, or a power bank, a little planning goes a long way. I’ve gone from frustrated (“Why is my camera dead again?”) to confident (“I’ve got this covered”)—and so can you.

At the end of the day, Arlo cameras are smart, reliable, and worth the effort. Just give them the power they need—on your terms. After all, peace of mind shouldn’t depend on a low battery icon.
