Talentcell Rechargeable 12V 6000mAh/5V 12000mAh DC Output Lithium ion Battery Pack for LED Strip/CCTV Camera/Telescope/Modem and More, Portable Li-ion Power Bank with 12.6V Charger, Black

I used it for my spectra pump while I was nursing and it worked amazing, kept my pump running for days, also works to keep my heated sweater warm, and great to charge my phone. Very happy!

I'm an automotive electrician and I modified this to be a 12v test source. I've been looking for a nice little 12v battery to put on my cart for quick testing for so long. This thing even has a nice on/off switch if I feel sketchy about what I'm testing. There's also reverse polarity protection! Ask me how i know.... lol. This is exactly what it says it is. It has been solid for me and endured some loads that certainly explore the limits of what it's capable of. Everyone at work knows what I mean when I say "grab the talentcell off my cart!". Talentcell you should make one of these with just two 16awg wires coming out with a straight wago lever nut on each. It would sell like hotcakes to sparkies.

As advertised. Holds charge well.

This was exactly as described and has worked very well for the last month. It was bought as a power supply for a portable stereo using a 12 v car receiver. It runs for several hours on a charge and takes several hours to recharge but I have not timed that exactly. It does not get warm and is way less money than most battery packs of a similar capacity. My only complaint and it is a small one, is that you must unplug the 12 volt output socket to put in the charging cord. It also requires you to know that the power switch must be on in order to charge the unit. Even if off, the indicator lights come on, giving you the impression something is happening. So, be sure you read the instructions before using it. Although it states it will put out 5v usb, I do not think I would have bought this unit for a 5v usb battery pack. There are similar packs of similar capacity that are much cheaper. However there were few for 12 v output. So it fills the bill very well and is much lighter and cheaper than an equivalent lead-acid 12 v battery. ***This is an update. I have had it for 10 months now and I use it for a few hours every weekend to power a portable USB speaker. It is still going strong and has been very reliable. Given that there are basically no other comparable units I am very happy with this unit. New update: I have had this unit for over 8 years and it is still running well. No failures, no problems except it takes a shorter time to deplete the charge. But for an 8 year old pack, it is doing really well. in fact, just because it is still working, I'm adding a star.

Works like it supposed to. Charges battery in know time.

This humble power source, though small in stature, is mighty in performance. It delivers a steady and reliable current, ensuring that all manner of devices, from lanterns to lutes, are powered with unwavering consistency. The lifespan of this battery is commendable, lasting far longer than many of its peers. Whether in times of peace or moments of need, it stands as a steadfast ally, ready to provide the energy required. One must also admire its ease of use. It fits snugly into any coat pocket, and its construction is both sturdy and safe. Verily, it is a product of fine craftsmanship. Yet, no tale is without its minor flaws. While this battery excels in many areas, there are rare occasions when its power does wane slightly quicker than anticipated under heavy usage. However, this is but a small blemish on an otherwise exemplary record. In conclusion, I bestow upon this battery a well-deserved 4 out of 5 stars! 🌟🌟🌟🌟 It is a reliable and valuable companion for all your power needs.

This rechargeable lithium-ion battery pack is useful for powering small electronics that require either 12V DC or 5V USB output. The dual-output design makes it flexible for different devices, and switching between ports is straightforward. I used it with low-power equipment and it delivered stable output without random shutoffs. The battery pack feels solid and well-built for its size. It holds a charge reliably and recharges in a reasonable amount of time. The included ports are convenient for portable setups where wall power isn’t available, such as temporary workstations or mobile projects. Capacity is suitable for moderate run times depending on the device’s power draw. It’s not meant for high-drain equipment, but for routers, small monitors, cameras, or similar electronics, it performs as expected and is easy to integrate into a portable setup.

Works great with Milwaukee M12 heated gear, and is far more comfortable than the original battery. BIG CON - this battery does not 'store' well, it needs to be actively used and charged, after a few months of non-use mine was dead.

Use it mostly to power motion detected led strips. Battery lasts weeks. Recently used it to power a noise machine during a power outage. Other battery packs would auto shut off since it’s very low power, but this one worked perfectly since it has a power switch. Lasted all night and was still almost fully charged.

Excelente, hasta la fecha sigue trabajando muy bien, cumple con lo que promete

Purchased to power my e-spinner. It works well and charges quickly. I'm happy with the size and the connectors provided.

Cumple sus funciones, robusta para situaciones de exposición pero aguantadora

Más que mejor, no necesito la 8 pilas para usar el telescopio, lo he usado seguido y mantiene funcionando el telescopio varias noches sin tener que recargar.
