Review: Over 8hr battery life and pays for itself after 4.5 years - I have wanted a way to keep my internet on during power outages for the security system to transmit alarms for about a decade. I was looking at possibly buying a small standby UPS which would have provided about 1 hour of backup time for around the same price as this product. I knew I had about 33watts at 120v when searching. I measured each of my 5 devices(Modem, Router/Gateway, Switch, AP, Smart Home Gateway) at DC and found they only consumed 14watts. That means the rest of the 19watts of power was wasted due to heat in the inefficient 5-1A power adapters. I also knew that it was all going to be less than 2A at 12V so this product would work. It actually comes out to be about 1.2A. Installation is easy and makes sense because now I only have 1 power supply VS 5 supplies. I have 3-12V devices, 1-9V device and a 48v POE injector. I am still waiting on a 12V to 48V DC-DC boost converter to be delivered so it has not been connected, but should work fine once it arrives. I decided to do a discharge test to verify the watt-hour rating and see if the supply could recover from a discharge. I disconnected the 12.6V in and connected a volt meter to the input jack. The input jack is directly connected to the cells so you can measure cell voltage regardless of the on/off switch position. As noted above I only had 4 of 5 devices connected for a total load of 10.5watts. The cell voltage started at 12.6v. I noticed that early in the test, about 1.25 hours, it went from 4 lights to 3 lights indicating only 75% charge remaining. The cell voltage was at 11.9v. It had only discharged just over 10.5watt-hours. The test continued for 3 hours without change and the voltage was still at 11.5v. At the 4.5hr mark the cell voltage finally reached 11.1v where I believe the 50% charge point should have been, but the 75% charge light remained on. With 10.5watts at 4.5hours it had discharged 47.25watt-hours which is also about half of the 98watt-hour capacity. At the 5 hour mark the cell voltage was 11.0v. Finally at the 5hour and 25min mark the cell voltage dropped to 10.9v and the 75% light started to flicker marking only 50% charge remaining. I then stopped the test since I did not want to too deeply discharge the battery or stress my electronics with under voltage. So one of my observations was the LEDs are really just a quick reference for if it is fully charged or partially discharged. I think whoever designed it might have not understood the nonlinear state of charge for a li-ion battery. It may be that they only had the option to design the LEDs to operate at 11.9v,10.9v, 9.9v, 8.9v with Zener diodes because that was all that was available. I don't know but it is something good to know during use. So 4 lights is around 100% to 85% and 3 lights is 85% to 40%. I did not test any further. I think 5 and half hours of backup is excellent and if I continued it looks like it would have continues past 8 hours before dropping to 9v. I don't think I will need it that long. If I have a long power outage I will run a generator. At least if I am away from the house the internet will continue to run during a power outage. Any security related messages can be passed. The other aspect I love about this is I now have less power adapters and the overall power consumption has dropped by consolidating power adapters. The power savings will pay for this device after about 4.5 years.
Review: Compact Powerhouse – Keeps My Network Alive for Hours - I love these little UPS units so much that I've already bought two of them, and I'll definitely get more when I expand my setup further. In the past, I've only dealt with bulky lead-acid based traditional UPS systems, which are big and heavy. This little battery pack (lithium ion) is a game-changer—it's incredibly small and compact yet packs a serious punch with multiple DC outputs (12V, 9V) plus USB-A and USB-C PD (up to 18W). No AC outlet, sure, but for DC-powered gear like routers, modems, switches, and mini-PCs, it's perfect. One unit is currently keeping my mini-PC running OPNsense, a TP-Link BE11000 access point, and the ISP's fiber ONT powered through outages—no hiccups, and it holds up for hours. The second one is handling multiple multi-gig managed switches, a Raspberry Pi, and an old Google Wifi unit in another part of the house. Both have breezed through real power outages without dropping connections, giving me plenty of time to ride out short blackouts or safely shut things down if needed. The build is solid—black rectangular metal-ish case that's easy to tuck away, with clear LED indicators for battery level and a simple on/off switch. Charging is straightforward, and it recharges reasonably quickly when power returns. If you're tired of giant UPS boxes and just need reliable backup for low-power network gear, cameras, LED lights, or similar, this is an awesome, portable solution. Highly recommend—worth every penny, and I'll keep buying them as my home lab grows. 5 stars!

## Questions & Answers

**Q: does this monitor temperature in the battery management system?  It would not be very safe always ON -- a fire hazard.**
A: Currently this battery without temperature protection,it have over charge/over discharge/over current/short circuit protection inside.

**Q: How does this support 12v/6a output if the charger is only 12.6/2a. can this be used with a higher wattage charger?**
A: At best, wattage in must be greater or equal than wattage out. You can't violate the laws of physics. Add up all of the output powers of all of the output ports (12V*1A*4 + 5V*2A + 9V*2A = 76 watts). If the ratings are to be believed, then the input power adapter MUST supply that total power. Divide the power by 12V for the input current (76W/12V = 6.3A), far higher than 2A that the 12V/2A power adapter can supply. Something is wrong, either the power adapter is under-powered, or the output ports are overrated. Which is it, vendor?

**Q: when will these be available again?se be available again?**
A: Who knows? I've bought 4 in the past 2 years and they were always available on Amazon. Talent Cell makes other units, but in my experience and IMO none of them is anywhere as good as this one. Worth waiting for if not immediately available when you check.

**Q: Does it need to be recharged after a power outage before hooking router & modem to it?**
A: no, it works like a UPS and keeps your router/modem running through the power outage; it will run most routers/modems for about 8 hours before running out of juice; if your power returns in a few hours, then no problem; the unit does not need "recharging" ... the whole idea of the unit is to tide you over power outages without hassles ... and without your router & modem losing power (or having to wait for recharging) ... I've had 4 of these running for over 2 years in a rural area that has frequent (brief 2-3 hours at max) outages during every rainstorm and they have worked flawlessly keeping not only my modem & router up, but also my wireless security system and remote cameras.

### ⭐⭐⭐⭐⭐ Very good, worked as expected
*by M***. on January 26, 2026*

Jan 26th, 2026: I have been using this for about a month now. I have lost power more than 10 times, and it has worked as expected. I have not been able to test it for long periods of time, but so far it has met my expectations. I will keep you updated in a few months. I love how the internet keeps working when I lose power :-D Updated April 14th, 2026: I was curious to see how long it would last, so I decided to go for the test. I only use it to back up my internet router, which powers an old phone connected to it. It lasted 24 hours and 18 minutes before it shut down. Really happy with the purchase.
