DROK® Backup Uninterruptible Power Supply UPS AC 110V-240V to DC 13.5V 12 Volt 7AH Battery Charger 1.5A Reviews
4 of 4 people found the following review helpful  Incredibly Small 20W 12V UPS/Power Supply, October 2, 2015 This review is from: DROK® Backup Uninterruptible Power Supply UPS AC 110V-240V to DC 13.5V 12 Volt 7AH Battery Charger 1.5A (Electronics) This thing is incredibly small. The module I received does put out 13.4V@1.5A which is acceptable. It does switch between the battery and AC power without dropping. It does have overcurrent protection that functions properly. It does provide 13.4V to the battery to charge it which is a little low. Its no load draw is too low for my Kilowatt meter to read accurately. With a 1.5A load it draws about 40VA/25W (No Battery) 80% efficiency which is ok. It does get a bit warm which could be the 5 watts lost. My application is to support a USB charger running a Raspberry Pi and a few network components. (I doubt seriously that it's 20 watts.) I bought this units bigger brother if I have issues :-) Help other customers find the most helpful reviews Was this review helpful to you?  
2 of 3 people found the following review helpful  Doesn't work for us., September 5, 2014 This review is from: DROK® Backup Uninterruptible Power Supply UPS AC 110V-240V to DC 13.5V 12 Volt 7AH Battery Charger 1.5A (Electronics) There were 2 reasons we bought this to replace our current solution and unfortunately it does not do either.
1. Battery drainage limit. When the power goes out we don't the battery to drain all the way because this is bad for the battery. In our initial test the battery voltage dropped down to 4.5v, far lower than we want it to go. We are hoping this would do what most electronics that run off rechargeable batteries do and cut the power at 10.5v or so.
2. Charge voltage. The description states 13.5v but the device only puts out 12.5v. Help other customers find the most helpful reviews Was this review helpful to you?
