Rechargeable 12V 3000mAh Lithium ion Battery Pack

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.

The good news: > Solid and well-built, nothing flimsy about it > Contains good-quality Samsung 3000maH cells > 12v output is pretty good, though drops to 11.4v at the rated maximum of 3 amps > 5v USB output easily provides 2 Amps of charging current and is not finicky about the load* The bad news: > The charger can barely deliver half the rated output current, which means longer recharge times > (minor) The power switch can easily be turned on if the battery pack is packed in a suitcase or back-pack or bouncing around in the glove box. A recessed switch would prevent this from happening. The photos tell the story of the poor charger, which in my estimation would likely take 12-16 hours to fully recharge the battery. With no load the charger provides the rated 12.6 volts but as soon as the load is increased the voltage drops and is down to 12.0 volts at only .27 amps. The most current I could get out of the charger was .30 amps but the voltage was down to below 9.6v, way too low to charge a 3-cell li-ion battery pack. The photos in the instruction manual show using the charger to both charge the battery pack and power a roll of LEDs at the same time - my tests indicate this charger could not provide the current needed to do both. * Many USB power banks have overly-sensitive protection circuits that shut down the power if there is a current surge for even a tiny fraction of a second. This means they can't be used with electronic devices that have switch-mode power supplies or voltage boosters, such as several portable music players I use. Even though the average current draw may only be 1/4 amp, most of my power banks will not power them, even though they are rated between 2 and 2.4 amps. The Talentcell power bank has no trouble powering these loads.

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.

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!

I needed this to power a portable computer project for short periods of time, and it's perfect for that, delivering 3A at 12V a or so without a hiccup for a project that needs decent power delivery. The Y cable to plug a device into the barrel jack isn't amazing, and looks a little weird, but works. I don't particularly like the included charger. It gets hot (not dangerously though), and it only charges at like 1A or 3W total, so it takes forever to charge up the battery. And if you have the battery off while you have the charger plugged in and the other cable connected to your powered device, that tiny current is split between the battery and the device, and that can actually cause issues with some devices (underpowered). So be aware of that. I kind of would rather have there just be a direct barrel to barrel cable included instead of the Y adapter. Do yourself a favor and use a 3A charger instead of the included 1A charger. Charge times are hours less.

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.
