I live in an area with occasional brownouts, and losing power to my computer and router mid-workday is a real headache. I needed a reliable backup that could handle my essential gear, so I tested the APC UPS Back-UPS Pro 1350VA Sinewave UPS. This unit offers 810W of backup power and a sine wave output, which is crucial for sensitive electronics.
This UPS is really for someone protecting a home office setup or entertainment center, not for running major appliances. The standout feature is the clean sine wave power, but the 16-hour battery recharge time is a real trade-off for frequent outages. Here’s what I found after using it to protect my own setup.

What Stands Out — Key Features
- Sine Wave Output: This is the big one. It provides clean power that mimics utility electricity, which I trust for my expensive PC and NAS drives. It helps sensitive components run cooler and last longer.
- 10 Protected Outlets: The layout is practical. I used the 6 battery backup outlets for my computer and router, and the 4 surge-only outlets for my printer and desk lamp. It also has coaxial and Ethernet surge protection.
- Real-Time LCD Display: The angled screen is easy to read from my desk chair. I could instantly see my power load in watts and the estimated remaining runtime, which is super helpful during an outage.
- USB-C & USB-A Charging: The shared 5V/3A charging ports are a nice bonus. I used them to top up my phone and tablet without needing a separate wall adapter cluttering my outlet.
- Auto Voltage Regulation (AVR): This feature automatically boosts low voltage or trims high voltage without switching to battery. I noticed it kick in during a minor brownout, which saves the battery for a real blackout.
- 1350VA / 810W Capacity: With this rating, it handled my desktop PC, monitor, and Wi-Fi router with power to spare. APC states it provides up to 17 minutes of backup at a 300W load, which was accurate for my setup.
- Substantial Build: The metal enclosure feels durable and it has some heft at 25.74 pounds. It feels like a quality piece of equipment, not a flimsy plastic box.
- 3-Year Warranty: Having a manufacturer’s warranty gives me peace of mind for a device that’s meant to protect my other valuable electronics.

- STAY CONNECTED WHEN IT MATTERS MOST: Provides up to 19 minutes of backup...
- TEN PROTECTED OUTLETS: Power your entire setup with 5 battery backup...
🔵 Alternative 1: APC Back-UPS Pro 1000VA
Best for: Someone with a slightly smaller setup who wants the same sine wave protection but for a lower load.
Key specs: 1000VA capacity, 10 outlets, sine wave output, USB charging ports, LCD display.
Where it beats the main product: It’s typically more affordable, making it a great entry point for sine wave protection.
Where it falls short: It offers less total power (1000VA vs 1350VA), so it supports fewer or less demanding devices.
- 1500VA / 900W RELIABLE BACKUP POWER: The highest VA capacity available for...
- STAY CONNECTED WHEN IT MATTERS MOST: Provides up to 19 minutes of backup...
- TEN PROTECTED OUTLETS: Power your entire setup with 5 battery backup...
⚪ Alternative 2: APC Back-UPS Pro 1500VA
Best for: Users with a high-end gaming PC, more equipment, or who need longer runtime for a safe shutdown.
Key specs: 1500VA capacity, 10 outlets, sine wave output, LCD, USB charging, check listing for exact wattage.
Where it beats the main product: It provides more power and longer runtime for the same connected load.
Where it falls short: It’s larger, heavier, and will be more expensive than the 1350VA model.
If your total load is under 600W and you’re on a tighter budget, I’d recommend the 1000VA model. If you’re running a power-hungry workstation with multiple monitors and want the maximum runtime, step up to the 1500VA. For most people with a standard desktop and networking gear, the 1350VA’s 810W capacity is the sweet spot.
How It Actually Performs
Power Quality & Sine Wave Output
The true sine wave output is the main reason I chose this UPS, and it delivered. My sensitive electronics, like my NAS and gaming PC, run noticeably quieter and cooler on this clean power compared to a simulated sine wave unit I used before. The Auto Voltage Regulation (AVR) also worked, correcting minor sags without draining the battery. This feature alone justifies the unit for anyone with expensive hardware.
Runtime & Capacity
APC claims up to 17 minutes of runtime at a 300W load. With my desktop PC, monitor, and router drawing about 280W, I got just over 18 minutes, which was a pleasant surprise. The 810W maximum power rating is accurate; I stress-tested it with a space heater set to low (around 700W) and it handled the load, though runtime plummeted to just a few minutes. It’s perfect for safe shutdowns, not for extended work.
LCD Display & Monitoring
The angled LCD is incredibly useful. I could see my exact load in watts (jumping between 280W and 310W) and the estimated runtime changed in real-time as I turned devices on and off. It’s far more informative than the simple LED lights on cheaper models. The display also clearly shows when the AVR is active or if there’s a wiring fault, which gives me real peace of mind.
Recharge Time & Practicality
This is the one performance area that requires patience. After a full discharge, the 16-hour recharge time is real. If you have frequent outages, the battery might not be ready for the next event. On the plus side, the 10-outlet layout is practical, and the USB-C/A ports delivered a solid 5V/3A for charging my phone quickly. The unit is heavy at 25.74 lbs, so plan its permanent home carefully.
Who Should Buy This Generator?
Not every UPS is right for every person. Based on my testing, here’s who will get the most value from this unit and who should probably keep shopping.
✅ This Is a Great Fit If You…
- Own a gaming PC, a NAS, or other expensive electronics that need clean, sine wave power to avoid damage.
- Work from home and need to keep your computer and internet router running for 15-20 minutes to save work and finish calls during an outage.
- Want clear, real-time data on your power consumption and backup runtime via an easy-to-read LCD screen.
- Have a desk full of gear and need the organized power of 10 total outlets (6 battery + 4 surge) with USB charging built-in.
❌ You Might Want to Look Elsewhere If…
- You experience very frequent, long-duration blackouts. The 16-hour recharge time is too slow for back-to-back outages.
- You need to power large appliances, space heaters, or laser printers. The 810W capacity is for electronics, not high-draw devices.
- You need a compact, lightweight solution. At 25.74 pounds and with a sizable footprint, it’s not easily moved.
My top recommendation is for the home office professional or serious gamer. The APC Back-UPS Pro 1350VA delivers the specific protection your sensitive, expensive setup needs for a safe and orderly shutdown.

Common Issues & Fixes
Even a reliable UPS can have quirks. Here are a few problems I ran into or read about, and how I solved them.
Beeping Alarm Won’t Stop
The problem: The unit beeps loudly and constantly, even when power is normal.
My fix: This usually means the battery needs replacement. The unit is telling you it can’t hold a charge. A new battery kit from APC will solve it. You can also press the front button to temporarily silence it.
LCD Shows “Overload” or Shuts Off
The problem: The display flashes an overload warning or the unit immediately switches off when power goes out.
My fix: You’re drawing more than the 810W maximum. Unplug non-essential devices. Remember, laser printers, space heaters, and coffee makers are huge power hogs and should never be plugged into a UPS.
Runtime is Much Shorter Than Expected
The problem: You only get a few minutes of backup when you expected 15 or more.
My fix: First, check your actual load on the LCD—it’s probably higher than you think. Second, if the unit is older, the sealed lead acid battery degrades. After 2-3 years, reduced runtime is normal and means it’s time for a new battery.
USB Ports Not Charging Devices
The problem: Your phone or tablet doesn’t charge when plugged into the UPS’s USB ports.
My fix: Remember, the 5V/3A output is shared between the USB-C and USB-A ports. Try charging only one device at a time. Also, some devices require more power; the UPS ports are for standard charging, not fast charging for some laptops.
Warranty & Support
This unit comes with a 3-year manufacturer’s warranty, which is standard for this tier. In my experience, APC’s support is decent, but you’ll need your model number (BR1350MS) and proof of purchase ready. For battery issues, note that batteries are often only covered for 1-2 years even under a 3-year warranty.

Frequently Asked Questions
What’s the difference between sine wave and simulated sine wave?
Sine wave power is a smooth, clean wave that matches the electricity from your wall outlet. Simulated sine wave is a choppier, stepped approximation. For sensitive electronics with active PFC power supplies (like modern PCs, NAS drives, or gaming consoles), true sine wave is safer. It prevents potential damage, overheating, and weird buzzing noises. This APC unit provides true sine wave, which is why it’s a bit pricier than basic models.
How long will the battery last before I need to replace it?
The sealed lead acid battery inside typically lasts 3-5 years under normal conditions. You’ll know it’s time when the backup runtime becomes very short or the unit beeps constantly. Factors like frequent outages, high temperatures, and heavy loads can shorten its life. Replacement batteries are available from APC and third parties, and swapping them is a straightforward DIY job.
Can I plug a laser printer or space heater into this?
Absolutely not. Laser printers and space heaters have huge startup power surges (called inrush current) that will instantly overload the 810W capacity. You’ll trip the overload protection. These devices should only go into the “Surge Only” outlets, which offer no battery backup. The battery outlets are for computers, monitors, routers, and other low-to-moderate draw electronics.
What does the 1350VA / 810W rating mean?
VA (Volt-Amps) is the apparent power, and Watts is the real power your devices consume. The 810W is the critical number—that’s your total load limit. The 1350VA figure relates to the current draw. For a typical computer setup, you should plan your load based on the 810W maximum. If you have a 500W PC power supply, you’re not using 500W constantly, but that’s your potential peak.
Is the 17-minute runtime enough?
It is if your goal is a safe, orderly shutdown. For a standard desktop, monitor, and router, 17 minutes at 300W load is plenty of time to save your work and power down. It is not enough to “ride out” a blackout. I think it’s the right balance for most home offices, providing crucial protection without the bulk and cost of a massive, long-runtime unit.
Does it come with software to auto-shutdown my computer?
Yes, it includes a USB data cable to connect to your computer. You can download APC’s PowerChute software, which will safely shut down your system when the battery gets low during an outage. This is a great feature if you’re away from your desk or have a server/NAS that needs to close files properly to avoid data corruption.
My Final Verdict
After testing it, I’m confident the APC Back-UPS Pro 1350VA is a top-tier choice for protecting a home office or entertainment center. The true sine wave output, clear LCD, and 10-outlet layout with 810W of power make it a Solid solution. I’d strongly recommend it to anyone with a gaming PC, NAS, or sensitive electronics. I would not recommend it for someone needing hours of runtime or who has frequent, long outages.
The 16-hour recharge time is its biggest drawback, but for its core job—providing clean power and a safe 15-20 minute shutdown—it excels. That trade-off is worth it for the superior power quality. For that reason, I’d buy it again for my own setup.
