Talentcell 12V Lithium ion Battery Pack, 11.1V/9000mAh 99.9Wh Portable Power Bank, DC 12/9V and 5V USB Multiple Output Li-ion Batteries for LED Light Strip, CCTV Camera, Mobile and more, Black

Great customer support, they answered all of my questions very fast, I only been using the product for a couple of days and it works good on the 12v interface i get 12.4v, also i did a bit of research and it appears that my device has 9 LG branded 18650 batteries inside . LG along with Samsung and Panasonic make very good li-ion cells. Another positive thing is that the cells production year appears to be 2017 so they are fairly fresh. On the down side the USB port is outputting bellow 5V, sometimes as low as 4.6v, typical USB chargers output 5.2V that low voltage is not good for phone charging. The other negative thing is that the cells max current charge should not exceed 2500mAh per cell that means that if you use the included charger that is just over an Amp then it takes ages to charge and I mean ages... so i am not sure if the charging circuit of this device is that sophisticated ether. You can also say that it can be partially used as a UPS but when the mains is plugged in anything you connect to this battery will draw power from it not from the mains so it will discharge even on that scenario. Last thing on the positive side i liked also that they have included a few different cables. Over all a good product and good quality but would be nice if the Talentcell team gave this product an upgrade to charge at 2C (faster charge) and full UPS functionality.

I purchased this battery to use with a portable dvd player that requires a 9.5 volt supply, this battery has a 9 volt output jack which does the job well. Using the dvd’s internal battery I can play 2 full length movies before a recharge is required but with this backup battery, I can play 9 movies before recharging is required. Overall I’m very pleased with this battery and fully recommend it. The outputs are 12 volt, 9 volt and 5 volts (usb) which can be used to recharge a mobile phone / tablet etc. Great item if you’re out and about and have no access to mains power. It’s not cheap but it’s worth the money.

I’ve read a number reviews commenting on the capacity and discharge characteristics of this battery. From initial tests I have found the following: there seems to be no issue in maintaining 5.1V on the USB even at 2.3A, and even after 6000mAh of running. I therefore conclude the USB output works very well. The 12V output sat just below 11V after 4000mAh of running. I found this was strictly comparable with a high-end, “market-leading”, battery I have of the same capacity (albeit this battery has been through more charge cycles). So initial impressions are that the Talentcell is pretty good value, and any drop in the 12V output is almost identical to my LiIon battery that cost twice the price. If your need is just the USB output, then this battery looks a very good solution. If your application requires an absolutely flat stabilised voltage of 12V, then this may not be for you, but for my 12V application (and probably many other applications), this is a good cost-effective solution. It may be that the practical capacity is slightly overstated, but again I expect this is true for most batteries packs.

This is an excellent item, very versatile with 3 output voltages and included mains charger. Works very well, seems good quality, I am very pleased with it.

Power reserve lasts much longer than other power banks I have plus it's versatile for different voltages

I am using this to power a portable HF transceiver that will run from 9v to 14v. The 12v side of the battery can power it easily for a whole day on its normal duty cycle. It can also be used as a USB power pack so it has other uses too. I was able to buy mine when it was on special offer so it made a lot of sense to get one. This pack would not work if the radio shuts down if its not getting above a certain voltage though.

Item stopped working suddenly after 7 months. Contacted the manufacturer for assistance and no reply. Won’t be buying this brand again.

This is a great battery - used while travelling abroad. It comfortably ran my cap machine overnight. No issue taking on aeroplane and fits inside my cpap bag.

Enfin une batterie mini UPS capable de fournir du 2 ampères en 5 volts et du 8 ampères en 12 volts. Merci au vendeur TALENTCELL pour la réactivité enfin des vrais professionnels. Décidément j’ai mis longtemps avant de trouver ce genre de batterie. Plus de 10 heure d’autonomie en pleine charge cool. Je la recommande.

Talentcell has perfect service, first deivery was faulty and they send one which workes flawless. Thanks a lot...

Autonomie parfaite pour le moment (utilisation en 5V). Même si mon boitier était légèrement cassé à la réception, aucune incidence sur son fonctionnement. A regretter : le besoin d'un adaptateur pour son rechargement en France ( prise UK )

J"ai testé cette batterie avec une charge de 50W sous 12V. La capacité annoncée est bien là. En revanche, la tension chute avec le temps, en suivant la courbe de décharge d'une batterie Li-ion. A 80% de décharge, la tension est de l'ordre de 10V. L'adaptateur secteur fourni est de type anglais. C'est un bloc avec prise intégrée, il n'est pas possible de changer la fiche. Il faut prévoir un adaptateur. Il délivre 12.6V et sert d'indicateur de charge, il vaut mieux utiliser ce chargeur plutôt que le remplacer par une alimentation 12V tierce.
