Berapa harga uninterruptable power supply battery backup
 Show 4.0 out of 5 stars Works good as a battery powered UPS It works as described, it can power 12V devices like router and modem, or both, as long as the total current draw is less than 3A. The voltage output is 12.1~12.2V, and it has a voltage regulator that it doesn't matter the input voltage is 12.5V or 13.8V, the "output" voltage is fixed at 12.1~12.2V. The current can supply 2.9A in a load test without significant voltage drop (<0.3V), which is impressive.It's a slightly concern that your input voltage from your original charger is NOT passed through directly to the output, so, I have no idea whether the internal battery is kept "charging" or not, which will of course shorten the life of the battery.Also, it doesn't mention in the product description or manual anywhere what's the "transfer" time or switch time from the input to the battery powered, which is specified in a typical UPS. Which may indicate there is no "relay" involved and the battery output is "constantly" online and connected to the output, unable to verify this, but if it's true, it is not a good design for the internal battery.There are some markings on the 6 come-with conversion adapters, but not indicating what size is converting to what size, it takes some "trial-and-error" to figure that out.Input and output both are with the size of 5.5x2.5mm. The finishing surface is pretty good, light texture.Another concern is that there is no screw at all, not "serviceable" in any kind, and it's using proprietary LiPo battery instead of Lion batteries like common 18650. So, basically you will not able to replace the internal battery until it's totally dead.Overall, it works as described, when the input is out, output is automatically switched from the input line to the internal battery powered. Keep in mind if the output is less than about 300mA(which is uncommon), in about a minute, the power will automatically cutout. So, make sure the power drawn is at least 300mA or more.Since it's not normal user serviceable nor the internal battery can be replaced, how the circuit work or any "transfer" time is also unknown, so how long it can last will be unknown. But it works as expected, small in size. Reviews with imagesTop reviews from the United StatesThere was a problem filtering reviews right now.

Forgot that my ISP provided dish uses POE for their hardware on the roof supplied by a separate device. So my router works flawlessly but my internect connection does not. I need another similar device to supply POE backup power. Power in our area goes out frequently for 4-6 hours I had high hopes. The search goes on... Reviewed in the United States 🇺🇸 on May 27, 2022 My unit is powered by USB 2.0 and this doesn't come with a plug for it. Reviewed in the United States 🇺🇸 on January 14, 2022 I used the included adapters and the power hooks up just fine to my TP-link 4+1 port unmanaged switch. Fully charged the unit powered the switch easily during the 75 minutes of testing I did during LAN gameplay between 2 PCs. At the end of the 75 minute tests it hadn't even used up the first LED of battery capacity. That said It was a very small unmanaged switch. YMMV with bigger switches or a combined managed switch and firewall appliance. This seems exactly what it is advertised to be Reviewed in the United States 🇺🇸 on June 24, 2022 Keeps on my 8-port switch during power outbreaks for 15-20 min, not tested more. Has all reasonable plug sizes to fit. Reviewed in the United States 🇺🇸 on October 5, 2022 I purchased this in April. By October, the product was completely dead. It performed well during several power interruptions, but apparently it’s not a very robust design. Yet another clever and useful idea that was poorly implemented. Even when it was working correctly, I never liked the arrangement of jacks and adapters. It’s true that it can be made to fit any of the most common jack sizes. But they never seem to fit tightly and I was never completely confident that the power jacks were properly seated. It does have a battery charge indicator, but a separate indicator showing that it does (or does not) have DC in would have been helpful. Reviewed in the United States 🇺🇸 on March 12, 2022 I'm using this item to keep power on for my Litter-Robot II during unexpected power outages. It also prevents unnecessary cycling whenever power the goes out. It is small enough to fit in tight places. I wish I had this many years ago. Reviewed in the United States 🇺🇸 on April 7, 2022 Simple set-up. Make sure the adapter is a 9v on your mesh node or router. Not sure about how long it would last if power completely off. Has worked for brown outs so far. Reviewed in the United States 🇺🇸 on March 30, 2022 THIS IS A GOOD PRODUCT. WHEN THE LANDLINE WORKS OFF A FIBRE CONECTION [THROUGH O.N.T] AND THERES A POWER OUTAGE IT POWERS UP THE P.O.T[S] Top reviews from other countries5.0 out of 5 stars Per ora funziona, anche con un router da 36w (3A a 12V). Reviewed in Italy 🇮🇹 on May 28, 2022 Comprato dal venditore Shanqiu del marketplace amazon al prezzo di 40 euro. Il modello è quello da 12V, potenza massima 3A (36W), batteria(in realtà internamente sono due batterie in parallelo) al litio da 10000mAh di
capacità (10Ah). Secondo le dichiarazioni del produttore, quindi, la batteria è molto più "grossa" di quella degli altri "mini UPS" per router/modem (gli altri modelli che ho visto avevano batteria tra i 2200mAh e gli 8.800Mah). 2.0 out of 5 stars Moins de 4.7V au lieu de 5V Reviewed in France 🇫🇷 on November 4, 2021
La tension de cet onduleur ne tient pas du tout la charge. 4.0 out of 5 stars Ottimo per modem e piccoli carichi. Reviewed in Italy 🇮🇹 on December 17, 2021 Salve a tutti. Oggi vado a parlarvi dell'acquisto di questo mini UPS utilissimo da utilizzare con apparati che richiedono piccoli carichi come modem-router, telecamere di sorveglianza, ecc.. Personalmente l'ho comprato per utilizzarlo con un Amazon echo dot in quanto nel mio comune va via spesso la corrente ed ogni volta poi son costretto a rifare le impostazioni di setup per far rifunzionare Alexa. In confezione ci sono vari spinotti che ci permettono di collegarlo alle varie entrate/uscite di alimentazione. Per ora non ho riscontrato nessun difetto di funzionamento o problema in particolare. Spero di esservi stato utile, resto a vostra disposizione e vi aspetto con la mia prossima recensione. BYE. 4.0 out of 5 stars Ottimo per modem e piccoli carichi. Salve a tutti.

Fa il suo dovere ma tenete conto che dovete acquistare alimentatore quindi il costo complessivo è pari o leggermente maggiore di uno già provvisto. Il vantaggio è alimentatore che ho preso è universale posso eventualmente utilizzarlo in altri ambiti.
