Genuine Samsung 3400Mah Wireless Charging Battery Pack

Make sure to order extra battery pack. Nice to have while one is charging.

Ibiught it for the magsafe for my Samsung S22, now I have a phone that can use a magsafe charging battery

I like the wireless cameras with the easy to change out battery pack. The 3 cell is much better than the 2 cell.

Like the headline says It powers 2 Samsung wireless charging pads with 10 watts each. Charges up my gear 2x faster

Used for charging speed light, battery pack, and trigger batteries

Correct battery pack for my Samsung camcorder ... good price, fast shipping and the battery even came pre-charged !

Excellent, genuine Sony battery.

Genuine Nikon battery… gets the job done.

I bought this item because I was sick of going through batteries for my pocket pen light. I really like that there is 4 batteries in the pack and each battery has its own charging port, as well as the supplied charging cord being able to charge all 4 batteries at once. I have been using these batteries for a couple months now and I will say for a rechargeable battery the run time is pretty darn good.

After ~5.5yrs, I noticed the internal cooling-fan began running full-time (quiet, but usually only runs if the batteries require charging, such as after an outage), and the usually-cool lower vents of the UPS were now a bit warm due to active charging circuitry. Then the normally 100% charge-level LCD indicator at times showed only 80% despite no outage. Time for a new battery pack! The most involved part was shutting down & disconnecting & eventually reconnecting all the protected equipment. After all was disconnected, out of curiosity I turned the UPS off & then back on - the charge-level indicator dropped from 100% to 60%! The old battery pack was in worse shape than I thought. Replacing the pack involved removing a couple screws at the bottom of the UPS & then sliding the face-plate down, then out. Then disconnect the power connector from the old pack, slide the old pack out, new pack in, reconnect the power connector & reattach the face-plate. Simple & quick! The charge level indicated 100% as soon as I turned the UPS back on - I let it charge for the recommended time anyway although I don't think that was necessary in my case because there was never any indication it was charging: the fan was off again & the lower vents cool to the touch again. My UPS seems to have a separate minor issue - a poorly connected LED that is supposed to illuminate the Power Button when the UPS is turned on. Instead, on mine, sometimes it's lit, sometimes it flickers, but usually it's off. The new battery pack didn't change that - the caution being that if the UPS has a more significant dysfunction, replacing the battery pack could be an expensive way to find out the issue isn't the battery pack. One last comment: Unlike APC, CyberPower unfortunately doesn't seem to have a recycling program for their spent battery packs.
