Talentcell 12V 3000mAh Portable Power Bank, DC 12V/5V USB Dual Output for LED Strip, CCTV Camera, Mobile Phones, Heated Jackets and More, 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.

Works well to power a QMX amateur radio. Plenty of battery life for this little radio. Excellent quality, charging/distribution cable works natively on the QMX also.

Talentcell is the gold standard for portable powerbanks i have more than a few of them for a variety of different things.

Works great for my diy NVG’s. Not too heavy, holds power for a while. I did notice some drain when it was off, but what battery doesn’t do that.

Works exactly as expected. It’s compact, lightweight, and holds a good charge. The battery has been reliable every time I’ve used it, and it’s easy to recharge. Great value for the price.

Easy to work with, charging takes a while, but man does it hold the charge! If this is the right size for you buy it, you'll be happy with it.

If you have a (tr)uSDX transceiver and are looking for a portable power source, this is it. I use two Ranger bands to hold the battery beneath the radio--it looks like it was made for it. It offers full 12v power for your radio so you can activate 5w transmissions. Comes with a 12v wall charger and a USB port so you could charge your phone if needed. Perfect addition to your Radio Manpack.

Used for QRO ham radio - works like a regular 12v battery. Only complaint is the on/off switch is too easy to activate.

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

Me sirvió para encender teclados, Yamaha CK88, Studiologic Numa Compact 2x, prácticamente cualquier teclado y lo mejor es que con un inversor de fase pude encender una Caline 5 y tener toda una pedalera analógica, inalámbrica!! También enciende pedaleras digitales NUX, Valeton, Ammoon, Amplificadores Mini Fender.

Love it, this is actually way more powerful than i needed. It takes me weeks to run it empty, and even then, it has never really gone all the way to dead for me, it just keeps going. I'm using it with an adapter for a very specific device known as MFLB and with its 12V to 1.5V adapter to power up the device, which needs a 1.5V input and this seems to work very well. Occasionally i use it to recharge my USB devices too, but not very often. I wish that the deign was a little more attractive. It looks quite boring, finish is not very smooth and overall it's not appealing. But hey, it works and there is virtually no competing product on the market, so i'm still giving 5 stars. The only other thing i wish for is that they made a smaller version of it. Like i said, this has way more power than i need, and it's bulky compared to my other power bank. I wish they made one half this size, even if it was the same price, I'd buy it. They make only bigger ones, this is already the smallest model as far as I know.

Fait plusieurs année que je l'ai et il fonctionne très bien

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