Review: Is this item safe for use with Li-ion batteries? - Excellent product. Good price/value. Works as advertised. Quick delivery. Primarily purchased to replace a lost 12v charger for our old, Li-ion JobSmart flashlight - the Anne Bonny of our flashlight fleet. She's been dropped from ladders, crushed by a tractor, epoxied back into frankenlight form and returned to service several times. It has the older style pin jack type connector. Secondary uses will include powering my Dad's 1974 Sperry Remington SSR-8 calculator to avoid the dreaded green death of leaking batteries. it has a blue-green LED display that rapidly flashes out intermediate results while calculating log and trig functions, just to let you know that it's working on it and will get back to you with an answer before Dexter works it out on his K&E Polyphase Duplex Decitrig. Is this item safe for use with Li-ion batteries? The ad copy and documentation don't explicitly state if it is. As I recharged the flashlight (which had stopped lighting months ago) I kept checking the temperature of both the charger and the flashlight until it was fully charged and noticed no temperature rise, so ... fingers crossed.
Review: Just what was needed! - I have a blood pressure monitor that just EATS batteries. It, fortunately, also accepts AC power. However, after just a couple of years, I noticed the wire leading into the jack to the device was breaking and before I could figure out what happened, one side of the dual-wire broke entirely. This, with the multiple plugs available and the multiple settings for output power was just what I needed. Once I was able to see the symbol for the power requirements of the port (TINY printing), I chose this device as a replacement. I wasn't sure which of the two largest ports to use as both seemed to fit. I chose the 2nd largest, fearing the other might be too tight and get stuck in! It worked fine! I'm now able to bypass expensive AAA batteries and can use this elsewhere if needed. The only negative (and that is not worth a decrease in stars) is that the wire is flat 2-part. I feel that if it were round, it would be stronger and last longer.

### ⭐⭐⭐⭐ Power is important!
*by R***R on July 29, 2020*

This product is cool, however it didn't help work my Tascam 4 track tape cassette recorder. I need 9 volts to work the tape machine, and the 9 volt plug didn't work for my machine. Maybe it's a fluke! Flukes are no big deal. I'm thinking maybe my tape machine is just special :) I'm assuming this product does work for other household items—in which case that's great. It's great to have tools that give you power.
