TalentCell 12V Lithium-Ion Battery Pack For LED Strips, CCTV Cameras & More – Rechargeable With Multi-LED Indicator Review

Bought for depth sounder in sailboat with solar panel. The lights on this Power Supply seem to indicate the 'quality' of charge (juice it is getting) as well as the state of charge (how much juice is left) when running the depth sounder. Kind of fun to watch the lights change with the changing availability of sun light on the solar panel. A bit of caution though, Lithium and water don't mix. There are videos on line that show the explosive effect of various chemicals with water.

I bought this and straight out of the box, it does not charge AT ALL. I contacted Best Buy support and stayed on the phone with them forever and still didn’t come to a resolution. So I’m stuck with a paperweight and I’m out 30 something bucks. I will NEVER use this company again. At least on eBay you get your money back if something you buy is faulty. Wish I could leave negative stars.

I bought this product to use with my spectra breastpump based on the reviews I read. I now question whether they are real reviews because none of them mention that you need an additional cable to be able to use the battery pack in this way (a Male to Male 2.1mm x 5.5mm Plug DC Power Adapter). This product does not provide all items needed to power the pump and I think the reviews left previously are misleading because none of them mention this. Once I bought the additional cable, it powered the

I brought this to make my spectra s2 pump portable and it works like a charm and stays charged for up to 2-3 days when needed so battery life is great. To recharge this batter it doesn’t take more than 30 minutes usually and the charger it come with indicated when it is fully charged

Dislikes are none so far. I like the compact design. I've made a 5 watt, 12 volt light for it that has lasted close to 7 hours doing auto brakes, plumping and lots of other jobs that require a small powerful light. The price is not bad either. This would be handy during a power outage or camping where one might want a light to take along when doing "personal body functions" on a dark night. I don't often post good reviews on products offered on the internet. This one is the exception. I bought…

when i used this item for the first time i noticed that their was a little extra play in the female portion of the battery. I used it a couple of times and became increasingly frustrated by this. It forced me to have to play around with the wire before the contact was made good. finally after about 3 months I contacted the seller and briefly explained what my issue was. 2 days later I received a brand new battery in the box and was told that I could keep the old even though it still worked, but

I bought this battery to use for QRP (low-power) amateur radio use. My rig's typical duty cycle is 50mA idle, 450mA on transmit. Using computerized battery testing software/hardware, I took this battery from a full charge down to 8.5V to better understand its capacity before I went out in the field with it. With the aforementioned duty cycle, it registered 2417mAh. Not the full capacity, but not too far off either.For my use case, it's perfect, giving me over 10 hours of radio fun on a single…

We are using this to run a custom lighting setup on a recumbent tricycle. We are getting 2 hour burn times with a pair of Supernova Mini headlights and a Supernova M99 taillight. Pretty impressive. Wish there was a switch on the other end of the battery. We tested the cells on our 18650 drawdown rig, and they performed very well, near the numbers of expensive brand name cells from LG or Samsung. Good value.

I bought this to make my breast pump cordless. It works great, I just velcro it on. I pump 6-7 times a day, and plug it in overnight to charge. It's a game changer not being plugged into the wall.

Certainly does the job, and the battery lasts super long. The ONLY things keeping this from a 5-star review are A. it’s a little heavy, and B. it takes quite a long time to charge. Otherwise, I have no issues and have bought several more of these in different amperages for different applications. For the price, you cannot beat it. These things are super versatile.

The cells in the pack are in a blue shrink-wrap from which the specs have been wiped with some solvent, presumably to obscure the fact that the cells are not 3000mAh as advertised. The streaks from left-over ink are clearly visible. Hence 4 stars.Something to note: I short-circuited the pack due to an accident and the short-circuit protection kicked in. After removing the short circuit I could not get any output until I read the datasheet of the battery protection chip and discovered that the…

With a m2m cable makes the spectra2 portable. Very easy to use and holds charge well. Small enough and light enough to make travel convenient (at least compared to the clunky spectra2).

I bought this for my spectra breast pump, and it let me go more places In my home. It freed me from being my a plug in. I even can pump on our boat! I gave it 4 stars because I’ve noticed the a/c plug ins aren’t really secure. Still works, but it’s become finicky.

Bought this to power a LED panel that only came with an AC adapter. The LED panel was 12 v input so I tried this out. Got over 2 hours on the panel (much larger than camera top size) and was amazed. Ran long and bright! Just ordered the larger version for my other panel. The larger one of this also does 5v USB for charging phones etc.NOTE: As this has a lithium Ion battery, expect longer delivery times than promised. Cannot go air, and even ground takes longer.

I like that it comes with a standard power port. Using this to power my Milwaukee heated jacket. This pack has a very slim fit in the pocket and lasts forever! Very pleased.

I bought this battery hoping it would bring some convenience for on the go power for my 12v breast pump (Spectra S2). I affixed it to the bottom with velcro. I am blown away! I initially charged it for about 8 hours and have been using it ever since without recharging. I have pumped 10 times for 25 to 30 minutes each session and the pack still has 4 out of 5 lights on! I am very confident that I can get several days out of the battery between recharging.Edit: This battery lasted for 20 pumps on

This is my fourth child and I wish I had this with my first! I had previously used the AA battery pack. It is so much better not ever having to think about finding an outlet or having 8 AA batteries on hand, which by the way only last 2 pumping sessions before you can tell the batteries are getting weaker. I’ve used this new rechargeable battery 5x a day for a week and still have full strength suction. This is worth every penny! I wish I had found it sooner. Get yourself one!

This is the second battery pack I’ve purchased for speaker projects. I like everything but the price. Just seems a bit high for what you are actually buying.

This works exactly as expected. I purchased to make my Spectra S2 portable (insurance wanted me to pay extra $70 for S1)I added a bit of heavy duty velcro to it and stuck it to the pump. I'm so excited about this! Now I'm not tied to chair while pumping!Because I just bought I cant attest to battery life or over all longevity but other reviews say battery lasts a while. Sounds even better than S1 battery life (3hrs)!So for less than the S1 upgrade I have my own upgraded, now portable pump…

I ordered this to make my spectra breast pump mobile because I’m a single mom to three and I couldn’t pump when I needed to because I was stuck to a wall outlet. I ordered a separate double male cord to make it work but it wasn’t necessary because it came with one. Battery lasts about two days with frequent use. I pump 6-8 times a day and it still lasts. The product arrive fast and packaged well. Definitely recommend.
