As advertised. Purchased to run electromagnetic pendulum clock because of steady voltage. Supplied with one short charging cable having one USB A male plug end (to charger) that splits into four USB C male plug ends to simultaneously charge four batteries. Looks a bit Christmasy with all four purple batteries dangling and blinking together while charging.

The idea of these is on target. C Li-ion battery with built in charging circuitry. Very convenient. Unfortunately they have so far failed to live up to the claim of 6000 mWh (6Wh) capacity. One of the four has totally died already as well.The first test was disappointing but I chalked it up to possibly not charging them enough when received. They only lasted about 10 days in 3 LED candle used for testing. It uses three batteries. So I fully charged them up for another test. The results were about the same. Pulled them out and measured 1.1v, 1.1v, and 0.1 volts: so this last battery has gone bad. I'll test again without the bad battery (it was a four battery set) but expectations now are low as these are supposed to be a "1.5v constant Voltage Battery".The LED candle test device uses three C batteries and runs the light 'on' for 6hr a day then goes into low power mode keeps the timer running for 18 hrs 'off' until the next 'on' time. It runs this way until out of power or turned off.With a standard C battery set the candle will run for almost 3 months.With a rechargeable NiMH 5000 mAh which deliver 1.2v instead of 1.5v the candle will run about 1.5 months.With the Li-ion 6000 mWh batteries it only ran 1.5 weeks, tested twice.Yes, mAh is not mWh, to compare Li-ion mWh to NiMH mAh divide Li-ion mWh by 1.2 - so the Li-ion battery has the same 5000mAh capacity as the NiMH battery.The short operating time might be due to using the bad battery twice, but only the next test without the known bad battery will verify that.If possible, I'll update the review when the next results are available.However 1/4 of my investment in these is already gone, and these are not inexpensive at $7.75 each.John ZUpdate. After fully charging, eliminating the bad battery I measured all three at 1.51v before loading into the LED candle. Turned on 11/24 - stopped working on 12/3 so ONLY 9 days! measured again all three batteries down to 1.1vThese definitely are not comparable to either a std battery or NiMH rechargeable battery either.I will not buy more of these already wasted about $30...John Z

These batteries generate 1.5 volts and maintain this almost throughout the discharge cycle. The charge quickly through a USB-C connector ( like latest iPhone), and last a long time. As they are li-ion they don’t have charge memory problems like old ni-cads, produce 1.5volts rather than 1.2 volts ( like Ni-mh), are fully rechargeable and fit perfectly into a c-cell battery slot. This was a great purchase.

They all charged on one usb split four ways, and that worked, but one of the batteries is a did. Won't charge, won't work.
