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.

Love this thing . I use it to provide lights to my safe. Lasts a couple months before having to recharge it

The media could not be loaded. Was looking for something like this for awhile for my scooter's Underglow with an ON/OFF Switch. This compact battery is great.I have 2 strips from an underglow kit for a vehicle. Wired it up and had an adapter that uses a DC circular style connection for power and ground.This is great as the unit itself feels pretty thick and durable. It lasts quite long as well. I had these strips on for around an hour or two and the bar was still within the 5/5 range. The button is sturdy as well and has some spring on it. Definitely not a cheap unit and quite compact. Amazed at this product.Overall:Price: 10/10Ease of Use: 10/10Performance: 10/10Quite satisfied with this, was using a powerbank before that doesn't have a on/off button so I had to disconnect my underglow strips manually on my scooter. Now it's just a click away :)

Made a little caddy to attach it to my fpv goggles, works great and powers them for a very long time.

The battery is very good and definitely surprised me. I initially used it to run a Lepy LP-2020A class D amp for a Bluetooth speaker project. The speaker got quite loud before I noticed voltage drop (the amp's light was dimming slightly). The battery life was outstanding while running the Lepy amp. My car had recently broken down for good and I decided to see how long this thing could run my car stereo for. I ran a double din head unit driving two speakers for 3 and a half hours before the battery died. This was the first time I could the battery. This is also wear the charger showed it's weaknesses. The charger cannot charge the battery in a reasonable time. I looked at it and it says it can only output 500mah. 500 mah is lower than most usb blocks! My problem however is that running the car stereo, the battery still discharges. Not a sufficient charger for the job. That's all I can say.If it wasn't for the terrible charger, I'd give 5 stars. The battery is good, why not the charger?I included a photo of what I was running the battery off of which was quite impressive. That little box ran a double din head unit at decently loud volumes for 3 and a half hours.

I like the way it recharges so fast it’s easy to use it has a lot of funtions and it lasts a long time so I bought 4 of them thank you

Great product. Powers my TotoVision moniter, I use for my drone, for several hours. Built and priced well too.

Works well, used it for the past 6mo and have had no issues.
