Switches over with no ill effects on anything I have plugged into it. My laser printer pulls too many amps to go on the backup circuit (even with normal power on), but still gets the circuit protection through the other plugs. We've had a lightning storm come through with quick drop-outs and it caught all of them. Works great and no headaches to install.Update July 4, 2013 - The unit has never failed to activate and the time it supports has not dropped off, hopefully indicating the battery has not diminished in capacity. Extremely pleased with it. I did switch back to an inkjet and it handles that printer's load with everything else as well. ### ⭐⭐ 2.0 out of 5 stars Second time we’ve purchased, first failed after two years, this failed in four months *by D***X on Reviewed in the United States on November 10, 2023* We’ve had great luck with Panamax, with seven in house for entertainment systems. This model we’ve had in our home theatre. The first failed after two years, this one, bought to replace the first, failed after four months (purchase dare 15 June 2023). In each case, the power supply and voltage scrubbing is fine, but the battery loses charge, cannot recharge, and eventually won’t stay on owing to battery having no charge, simply beeps incessantly. Do not recommend this model. We’ll be trying another. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Must Have for your Entertainment System *by M***M on Reviewed in the United States on January 30, 2012* I live in a suburb where split second power outages are a weekly event. You don't really notice it unless if you're using your computer or entertainment center at the time of the outage. I have a Panamax M5300-EX Surge Protector, however that didn't stop my components from shutting off and reseting during each outage. It just protects the components from spikes in the electric currents.Since I bought this battery back up... it puts a smile on my face everytime the power goes out for 10 or so seconds and I hear the back up beeping. Its great to be able to keep enjoying whatever I'm watching until the power returns. Feels even better to know that my expensive entertainment equipment isn't being damaged. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/70829267-panamax-mb850-battery-backup-surge-protector](https://www.desertcart.tn/products/70829267-panamax-mb850-battery-backup-surge-protector) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-25*
