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

Let’s face it: no one wants to be left in the dark when it comes to home security. That’s why I’ve spent more time than I’d like to admit troubleshooting, charging, and recharging my Arlo cameras. If you’re like me—someone who values peace of mind but also doesn’t want to spend half the day tethered to a charger—you’ve probably asked yourself the same question: how long does it take to charge Arlo cameras?

The answer isn’t always straightforward. It depends on your Arlo model, the type of battery, the charger you’re using, and even the environment around you. But don’t worry. In this guide, I’ll walk you through everything I’ve learned—from personal experience, real-world testing, and a few late-night Google rabbit holes—to help you understand charging times, optimize battery life, and keep your home security running smoothly. Whether you’re setting up your first Arlo camera or you’re a seasoned pro looking for efficiency tips, this guide has something for you. And yes, I’ll even share the one mistake I made that cost me three days of camera downtime (spoiler: it involved a cheap third-party charger).

Understanding Your Arlo Camera Battery

Before we dive into charging times, it helps to understand what’s powering your Arlo camera. Not all Arlo models use the same battery, and knowing the differences can save you time, frustration, and maybe even a few dead cameras.

Types of Arlo Batteries

Arlo uses a few different battery types, and they’re not interchangeable. Here’s what you need to know:

• Rechargeable Lithium-Ion (Li-ion) Batteries: Most Arlo cameras, including the Arlo Pro, Arlo Ultra, and Arlo Essential, use these. They’re lightweight, hold a good charge, and are designed for frequent charging.
• Arlo Solar Panels: Not a battery, but a charging solution. These connect directly to compatible cameras and use sunlight to top off the battery. Great for outdoor setups.
• Built-in Batteries: Some newer models, like the Arlo Essential Indoor Cam, have non-removable batteries. You charge them via USB-C or micro-USB.
• AA Batteries (Arlo Wire-Free): The original Arlo Wire-Free cameras use standard AA lithium batteries. These aren’t rechargeable in the camera, so you’ll need to swap them out when they die.

Battery Capacity and Real-World Life

Battery life varies widely depending on usage. Arlo claims up to 6 months of battery life for some models under “ideal” conditions—meaning minimal motion events, moderate temperature, and infrequent live viewing. In reality?

• If your camera is near a busy street or a frequently used door, you might see 2–3 months.
• Frequent live viewing or night vision use can cut battery life in half.
• Extreme temperatures (below freezing or above 100°F) can reduce capacity by up to 30%.

So, while battery life tells you how long it lasts, charging time tells you how long it takes to get back in action. And that’s what we’re here to unpack.

Charging Times by Arlo Model

Now, let’s get to the heart of the question: how long does it take to charge Arlo cameras? The answer depends on your model, battery type, and charging method. I tested several models over a few weeks to give you real-world numbers.

Arlo Pro 3, Pro 4, and Pro 5

These models use the same 4,800 mAh rechargeable battery. Here’s what I found:

• With the official Arlo Magnetic Charging Cable: ~4–5 hours from 0% to 100%. The cable delivers 5V/2A (10W), which is efficient and safe.
• With a standard USB-A to USB-C cable and 10W wall adapter: ~5–6 hours. Slightly slower, but still reliable.
• With a fast charger (18W USB-C PD): ~4.5 hours. No significant speed gain because the battery and camera don’t support fast charging beyond 10W.

Tip: I left one camera charging overnight (10 hours) just to test overcharging. No issues—Arlo has built-in overcharge protection.

Arlo Ultra and Ultra 2

These premium models use a 4,600 mAh battery (slightly smaller than the Pro series). Charging time is similar:

• Official Arlo charger: ~4–5 hours
• Third-party USB-C charger (10W): ~5–6 hours

One thing to note: the Arlo Ultra supports solar panel charging, which can keep the battery topped off during the day. If you live in a sunny area, this can reduce the need for full charges.

Arlo Essential (Indoor and Outdoor)

The Arlo Essential Outdoor uses a 4,800 mAh battery, same as the Pro series. But the Indoor model has a built-in 3,000 mAh battery and charges via USB-C.

• Essential Outdoor (with Arlo charger): ~4.5 hours
• Essential Indoor (USB-C, 10W adapter): ~2.5–3 hours
• Essential Indoor (with a 15W fast charger): ~2 hours

The smaller battery in the Indoor model means faster charging. I charged mine during a lunch break and had it back up and running in under 2.5 hours.

Arlo Wire-Free (Original)

These older models use AA lithium batteries. You can’t charge them in the camera. Instead, you need to remove them and use an external AA charger.

• With a quality AA charger (e.g., Nitecore, Panasonic): ~1.5–2 hours per pair
• With a cheap charger: Could take 3+ hours and may damage batteries over time

Personal note: I tried using rechargeable AA batteries once. Big mistake. They don’t hold up well in cold weather, and I ended up with a camera that died after two weeks. Stick with lithium AAs for these models.

Arlo Go (LTE)

The Arlo Go uses a 6,000 mAh battery because it relies on LTE data, which drains power faster. Charging time?

• With Arlo charger: ~5–6 hours
• With solar panel (optional): Can maintain charge in sunny conditions but won’t fully recharge a dead battery

Factors That Affect Charging Speed

Charging time isn’t just about the camera—it’s about the whole ecosystem. Here are the real-world factors that can speed up or slow down your charge.

1. Charger Quality and Wattage

This is the biggest variable in charging speed. I learned this the hard way when I used a $5 Amazon charger. It took over 7 hours to charge my Arlo Pro 4. Why?

• Low-quality chargers often deliver less than the rated wattage.
• Some don’t support the correct voltage/current profile (5V/2A).
• They may overheat, triggering safety cutoffs.

Pro tip: Use the official Arlo charger or a reputable brand like Anker, Belkin, or Aukey. I now keep a spare Anker Nano 10W charger in my camera bag—it’s compact and charges my Arlo in 4.5 hours.

2. Cable Type and Length

Not all USB cables are created equal. I tested three:

• Official Arlo magnetic cable: Fastest and most reliable. The magnetic connection is convenient, but it’s proprietary and expensive to replace.
• Short (3ft) USB-C to USB-A cable (high-quality): Nearly as fast as the Arlo cable.
• Long (6ft) or thin-gauge cable: Slower—took 6.5 hours. Voltage drop over long distances reduces charging efficiency.

My rule: Use short, thick cables (preferably 24 AWG or lower) for faster charging.

3. Ambient Temperature

Batteries don’t like extreme temps. I left one camera charging in my garage during a winter cold snap (20°F). The charging speed dropped by 40%, and the camera showed “low battery” warnings even at 30%.

• Optimal charging temp: 60°F–80°F (15°C–27°C)
• Below 32°F (0°C): Charging slows or stops to protect the battery
• Above 100°F (38°C): Same effect—thermal protection kicks in

Keep charging indoors or in a temperature-controlled space. If you’re charging an outdoor camera, bring it inside for a few hours.

4. Battery Age and Health

Like all lithium-ion batteries, Arlo batteries degrade over time. After 2 years of regular use, my Arlo Pro 3 battery now takes 5.5 hours to charge (vs. 4.5 when new) and only lasts 2 months instead of 4.

• Signs of battery wear: Longer charge times, shorter runtime, frequent “low battery” alerts
• Solution: Replace the battery (Arlo sells replacements for $30–$40)

5. Charging While in Use

You can charge your Arlo camera while it’s active, but it’s not recommended. Why?

• The camera draws power for Wi-Fi, motion detection, and night vision, slowing the charge.
• Heat buildup from operation + charging can stress the battery.

For fastest charging, turn the camera off (via the Arlo app) or remove it from the mount.

Smart Charging Tips to Save Time and Extend Battery Life

Now that you know how long it takes, let’s talk about how to charge smarter. These tips come from trial, error, and a few “why didn’t I think of that?” moments.

1. Charge Before It’s Critical

Don’t wait until your camera hits 10%. I made this mistake once—left my front porch camera at 12% overnight, and it died by 6 AM. The delivery guy rang the doorbell, but I missed it because the camera was off.

• Best practice: Set a monthly reminder to check battery levels in the Arlo app. Charge at 30%.
• Bonus: The app sends push notifications when battery drops below 20%. Enable them.

2. Use Solar Panels for Outdoor Cameras

If you have an outdoor Arlo (Pro, Ultra, Essential), invest in an Arlo Solar Panel. I installed one on my backyard camera, and it’s been running at 80–100% for 8 months straight.

• Charging speed: ~0.5–1% per hour in direct sunlight
• Best for: Areas with 4+ hours of daily sun
• Cost: ~$50–$60, but pays for itself in battery replacements

3. Keep Spare Batteries on Hand

For cameras with removable batteries (Pro, Ultra), buy an extra battery. I keep one fully charged in my desk drawer. When one dies, I swap it in and charge the other.

• Time saved: No downtime. You can swap in under 30 seconds.
• Cost: $35–$40, but worth it for peace of mind.

4. Use a Charging Station

I built a simple charging station using a multi-port USB hub and a power strip. Now I can charge 4 batteries at once.

• Label each battery with a number to track rotation.
• Use a timer or smart plug to turn off the hub after 5 hours (prevents overcharging).

5. Avoid Third-Party “Fast” Chargers

I bought a “12W Arlo charger” off Amazon. It charged my camera in 3.5 hours… but the battery swelled after 3 months. Arlo batteries are designed for 10W max. Anything higher risks damage.

• Stick to 5V/2A (10W) or lower.
• Check reviews: Look for “Arlo compatible” and “no overheating.”

Final Thoughts: Charging Smarter, Not Harder

So, how long does it take to charge Arlo cameras? On average, 4 to 6 hours for most models—but that number can shift based on your setup, habits, and environment. The key isn’t just speed; it’s consistency. A dead camera doesn’t protect your home, no matter how advanced its features are.

From my experience, the best approach is a mix of preparation and smart habits:

• Use the right charger and cable (official or high-quality third-party).
• Charge at 30%, not 10%.
• Keep spare batteries or use solar panels for outdoor cams.
• Monitor battery health and replace when needed.

And remember: charging isn’t a one-time task. It’s part of your home security routine. Think of it like changing the batteries in your smoke detector—small effort, big payoff.

Now, when your Arlo app pings you with a “low battery” alert, you won’t panic. You’ll grab a spare, swap it in, and have your security back in minutes. And if you’re setting up a new camera? You’ll know exactly what to expect—no surprises, no downtime.

Because at the end of the day, peace of mind shouldn’t depend on how fast your charger is. It should depend on how well you prepare. And now, you’re ready.
