I live in California where power outages happen frequently. Recently, I experienced a power outage which render my electronic devices, TV, and computer useless. I think we can all agree that life nowadays without your electronic devices, TV or computer is not fun.A co-worker who recently purchased this exact unit recommended this product. I was skeptical at first but for a cheap price of around $50 bucks, I said why not. If anything, it’s Amazon and the return process is painless.The package arrived undamaged and in a timely manner. The unit seems sturdy and well built. I tested the unit on my TV and computer. It seems to be an excellent unit if you are looking for a battery backup. There are 6 outlets, which is more than what I needed. I like to have extra outlet just in case there are additional items I need to power on. The battery was easy to use.So far so good. If you experience power outages or need a battery backup for emergencies, this unit will do its job. I will post another review if something goes bad. ### ⭐ good deal, short lived *by A***E on September 4, 2011* This unit was a much better value than what I could get at stores locally, but it croaked out about 14 months later ### ⭐⭐ After a couple of month, it was not working ... *by E***E on September 17, 2016* After a couple of month, it was not working properly. It would not keep its charge and drop at 20% after just 2 minutes . I had to replace it. --- ## 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.co.uk/products/39051840-maruson-800va-450w-line-interactive-ups-battery-backup-avr-overload](https://www.desertcart.co.uk/products/39051840-maruson-800va-450w-line-interactive-ups-battery-backup-avr-overload) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
