Talentcell Rechargeable 12V 3000mAh Lithium ion Battery Pack for LED Strip, CCTV Camera and More, DC 12V/5V USB Dual Output External Battery Power Bank with Charger, Black

UPDATE Additional into: I went ahead and bought the 12.6vdc/2amp power pack (Also made for this unit by Talentcell). Now I know I have all the power I need for both charging the battery pack and operating my 2 wyze cameras simultaneously. And I know it's powerful enough because the powerpack (original 500ma and the 2amp I just bought, has a red light when charging, and it turns green when all is charged); and with the 2amp it goes green after the battery pack is charged EVEN with the 2 wyze v3 security cameras connected. Again; great product and great company support. Highly recommend. I bought this to be a UPS (Uninterrupted Power Supply) for my Wyze v3 security camera during power outages. The seller was very quick and helpful in answering my questions on if it could be used as a UPS system for USB devices. They quickly answered all my concerns. I received the item, made sure it was completely charged, then with it still plugged into power I connected my camera to the USB port and made sure the power switch was on. The device powers my camera perfectly. When I manually remove the AC charging power pack, the camera doesn't even blip. Works perfectly. The device has built in safety features to protect against overcharging, overvoltage, overtemp, etc. I highly recommend this item as a UPS system for a security camera, Raspberry Pi computer, or anything similar. The 3000ma battery is strong enough to keep your item powered up for quite a few hours; until main power returns. My only suggestion for those wanting to use it as a 5v USB UPS system, is to get a different 12vdc power pack/charger. The one that comes with it is 12vdc 500ma. That's 1/2 amp. That is fine for charging the internal batteries, but it may not be big enough to run your device and charge the batteries. My Wyze camera uses between 500-750ma. So, chances are, in time, the camera would use up the batteries faster than they can be recharged. If you put a 12vdc 1amp charger on it, the battery will always be topped off 100% and the camera will still be able to operated by the charger power (pass through) and not off of the batteries. FWIW: The larger 6000ma model by this company does have a 1amp charger/power pack; but it needs more to charge twice as many batteries. So either way, if you want to use it as a UPS, I recommend getting a different 12vdc charger/power pack. You probably have a bunch sitting around the house. But overall.... This is a GREAT device. I've only been using it for a few days, but it's great. The battery backup stays fully charged, my camera gets it's power from the 12vdc charger/power pack; but has the batteries there as a backup during power outage. The batteries aren't continually charging once full. The device is completely COLD to the touch which shows that the batteries are protected from being overcharged. This is a great device; especially for the price. And having a seller that is #1 in customer service is a plug. Talentcell is definitely going to be my go to for first options in related items in the future.

Crazy good powerbank for the price. Lots of power that lasts all day and can charge decently quick. Perfect for working out, working on a film set, cosplay accessories, or anything else you can think of. Whether its for your phone or for other electronics, this battery is worth it!

I own two Talentcell rechargeable batteries and BOTH work flawlessly even after years of use as backups. I did have a slight hiccup with my newest, the charging plug had an issue. I contacted Talent support and even though it was months after my purchase, they responded quickly and sent me a new charging plug free of charge. I can't say enough about the Talentcell rechargeable batteries and the EXCELLENT customer service they provide.

I am interested in using this as a rechargeable battery pack solution for a vintage Zenith TransOceanic B600 shortwave radio. I needed a battery solution that could power a DC-DC boost converter as well as the filament string, through a 90V & 9V voltage regulated and current limited power supply. I did load test it from it's 12V output jack into a 250 ohm resistor. I fully charged the pack with the included charger, then, let it sit for a week before testing. The initial discharge voltage when the load was connected was 11.8V, with a 45mA measured load As the battery discharged, I recorded the voltage and charted the value on a graph (attached) After 49 hours with the same load, the output dropped to below 10VDC, making it unuseable for my application after that, but, it should easily give 12+ hours of battery power for the designed supply circuits. Once it got to below 10VDC, and used up 2000mA/H of capacity, I decided to see if the USB port would still put a charge into my cellphone. The pack still had one LED lit, and started to charge my phone, but after 5 minutes it shut down and stopped powering the USB port, so it was done. All in all, if they rated it at 2000mA/H it would be better truth in advertising, but, it still is a fair value. And, yes, the included wall wart tharger has a low output, but, that could help the batteries to not be damaged by a higher charging current

I needed a way to charge my heating aids while camping. Other packs would not recognize the small load and shut off after a minute. This thing works. Charges my hearing aids over night then phone in the morning, perfect. Lasted several days.

Excellent Supply

Amazing product! My 5V and 12V - 60 LED's have been running for over 4 hours on the rainbow pattern and the battery pack has only reduced one bar! Absolutely incredible!

Great little battery pack for constant on uses.

Received in time stated and in good condition. Perfect for job required.

El producto cumple en tiempo de entrega y calidad especificada.

Great product to power maker projects and more.

Actually I could not use it as the laptop that I wanted to power using this died.

Used this to replace a lead-acid cell in a small, seldom-used PA amp. Tucks easily into the original space. Works great, and I no longer will need to replace the lead-acid battery every few years! Works great because of the included AC charger and cable.
