Zinq Technologies Mini Ups for 12V Routers, High Power Fiber Routers, Broadband Modems | Seamless Automatic Switching | Upto 4 Hours Power Backup During Power Cuts (Black)

I purchased this in July 2023 and it has worked flawlessly till March 2025.Overall it worked well for 1 year and 8 months. I think it severed the purpose.

Worked fine for 1 year. Not working now. Seen many faces same issue. Think twice before buying it if its only works for one year.

Update 2...1. Item runs 1hr 14m @1A giving 15.465Wh, runs 48m @1.5A giving 14.82Wh whereas its rated at 22.2Wh & since its april'21 made, i'd say battery is defective & wont last me long, ordered replacement.2. Replacement runs 1h 32m @1A giving 19.39Wh, 1h 1m @1.5A giving 18.452Wh & being made in nov'20 i think this batt is alright. I'm keeping the replacement & ending my review unless item fails catastrophically.=======Update...1. This is what "make in India" has become- a plethora of Indian registered companies slapping their logo & selling chinese items in India, to cash in Indian sentiments. This is a generic item sold by slapping diff brand names like zinq, quantum (available right here on amazon) & prolly more. Even the boxes r exactly same... lol.2. Recharge rate is horribly slow @0.5A, so 2.2Ah will take 4.4hrs, considering losses 4.5hrs. That's why frequent power cut ppl r complaining about 1hr standby. So its basically for ppl with occasional power cuts (like me with community generator).3. Ups has to be turned ON to recharge... what? why? lame! This is another reason ppl r complaining about charging issue & since item is generic, ZINQ prolly doesn't even know... lol... such a dumb thing must be printed on the center of the box itself. I myself was fooled for 6hrs thinking that its charging but it went cold so checked with power meter & wow! It didn't charge a bit.4. Had i been younger with lotza free time, i could've made one myself for ₹80+80+80+150+50 for 1.8Ah one... Gone r those fun days! So I'm keeping it for ₹1001.** if any1 is reading my review, youtube search for "router ups" & lotza young ppl with free time have made such DIY.===============Damn this thing can output over 35watts of power @12v. For the 1st time something has out-specked my 35w load tester.Pros-1. Can output 3A or even more, that i could test. Great for sudden load surge.2. Very stable output 12-12.1v throughout 0-35w.3. Solid built, almost all possible connectors provided, seamless switching from AC to battery (obviously), easy to use.Cons-1. No polarity changing option for in/out. Some items/chargers do have center negative, for that i have to make my own cable.2. Since it went 3A or above, i dont think theres any overload/short circuit protection.3. Item got quite hot when run at 12v 2A for 15mins. I hope theres thermal protection.4. Item is sealed shut. Any repair or future battery change will be destructive.

Not working after one year. Work for only 5 min after power cut

designed to last.

Using from 2021 and in 2025 still work with more then 2 hours backup.Using with jio router.

Worked for 2.5 yrs for me max.1 star deduction as i couldn’t find replacement battery

Recurring power cuts had made me to look for the additional power supply for my modem for the constant network supply at my home during corona lockdown. This power saving tiny super product has made my survival long-lasting esp during lockdown times by connecting me with the internet until 3 years of its purchase from Amazon without any lag.
