Rechargeable 12V 11000MAh 9V 14500MAh 5V 26400MAh DC Output Lithium-Ion Battery Pack For LED Strip, CCTV Camera, Portable Li-Ion Power Bank With AC/DC Charger - Black Review

I used this to run my Transcend CPAP machine with a setting for 4-10 (it's an auto cpap; my normal setting is 7.) The battery lasted for 3 nights just right at 8 hours each. So this little guy ran 24 hours for a fraction of the price of the transcend multi night battery. I am thoroughly impressed. I'm a backpacker, and with 3 nights and at a weight of 495 grams, this just opened up my world to multi night backpacking trips without carrying excessive battery packs. The JMT is a distinct…

Update 9/2020: talentcell contacted me and sent me a replacement battery. They notified me that the warranty period is now 1 year but replaced the battery anyway, even out of the warranty period. The customer service is outstanding, which is why I can recommend the battery.Pro: Great battery life. Low price.Con: This battery stopped working properly after approximately 1 year. The 12v plug contact became loose and intermittently powers off. Appears to be a quality control issue. I contacted the

UPDATE #2: I opened the battery and found the batteries still good TelentCell is sending me a replacement PCB. This is above and beyond in the form of CUSTOMER SERVICE. So the 5 stars awarded include the customer service I experienced. .UPDATE: New unit arrived, all is well Thanks TelentCell for your follow up. I will purchase their products and recommend them as a vendor.I went to Talent Cell Technology and told them of my issue.I got back1. We will send you one replacement battery today via…

I purchased a small practice amplifier, which could either work with AC with it's built-in power supply, but could also take an external DC source. I purchased this to handle long periods of time if needed. Turns out it's even better than that. The DC draw from the practice amp isn't heavy, so I could probably run more hours than I would use the particular amplifier. I also could use this to charge a phone or tablet while being away from any AC power source. Glad I purchased this!

I have 4 of these. Different voltages and capacity ratings. I LOVE being able to go to Balboa Park to play my guitar through my stereo 30W amp without worrying about an AC outlet. A month ago one of these battery packs just quit. I had a back-up. I've been doing professional music for 45 years—You HAVE a back up! but the TalentCell that died just died. No warning. No nothing. It was fully charged and was working and then just shut down after like 3 minutes of run time! Probably the BMS (battery

I was looking for a way to make my Blackmagic ATEM Mini Pro portable. This works great. I bought the 1100Mah version and it came with both the 2.1x5.5mm cable and the 2.5x5.5mm 9v cable. I used the second cable (in reverse) in the 12v socket to power the ATEM Mini Pro. Works like a champ so far but I haven’t had time to test the run time or reliability. So far, I’m very happy and I’ll update my review if I get less than 3 hours of runtime or have ANY issues with it. This is a tiny investment to

Nice versatile Battery. I bought it for camping with my Phillips Respironics System One 460PBT. I turn off the humidifier and get about 2.5 full nights sleep on it. It uses the 12V output.It also will work as a gigantic USB 5V power supply. Charges my phone many times. Never counted but it goes for a long long time. .also works as a 9 Volt supply (but I've not used it that way)It seems pretty well built.I bought a second one, for longer camping, more capability and redundancy.This newer one is…

UPDATE 2: Talentcell replied to my email within a few hours and has already arranged a replacement. Their customer Service is EXCELLENT! Despite the slight issue with the battery, I very happy! Now back to making music. UPDATE: So I'm having a bit of an issue. The battery works great with my drum machine during the first half of the battery's charge. After the LED indicator drops to two green lights, I seem to be having issues again. I'm still getting about two hours of solid play time but…

Ordered 2, one came nonfunctional due to a quality control issue. The wrong charging port was installed in the device and the charger could not be attached. Ordered a new one and in the process of returning the defective one. In the photo, the left box is the defective pack, the bottom round plug has a center pole too large to allow the charger to plug into. The charger box on the right has the correct port. if you look closely, you can see the size difference for the center pin.That being…

This is my 2nd 12V/11000mAh Talentcell. The first one is working so well that I purchased another to daisy chain them together for longer battery life of my project. Yes you can use a splitter cable to connect both 12V ports together. They will connect in parallel meaning your voltage stays at 12V. They do NOT daisy chain in series (making it 24V). This is the way it should be. We can all purchase multiple of these power packs and add more battery life to our projects. Same applies for the 9V…

I bought this so I had a portable 12vdc supply for a thermo control board I bought to turn a 12v computer fan on/off when it reaches 22C. It's been hooked up for over a week now and only down to half. The fan kicks on for maybe 10 minutes a day and draws more power than the board.Wow, I'm impressed. Think I'll buy another one.Next I'll hook up a 12vdc - 6.5ft string of led lights and see how long it last. Update to come.

1 year update: Both still going strong. have used these a dozen nights or so now (Camping and power outages). Sat for 6 months and still went to full nights of use.I have the old school System 1 Bipap because it is one of the few that can handle such a high setting (goes to 20, but 18 is as high as any full face mask I've tried can handle without lifting off face). Using a single one of these I only got around 2-3 hours out of it. Using 2 linked together gave me a solid 8 hours of use even with

I purchased this as a battery pack to power my fish finder. The fish finder draws 12 V at 800 mA. I built a waterproof enclosure for the battery pack, which has worked well. On a few trips, the battery pack was able to power the fish finder for more than 6 hours continuously. I have been very happy with the purchase, as it looks very well built and did what I needed it to do. Unfortunately, a few days ago, I was recharging the battery. Luckily, I was in the same room working on another project,

UPDATED:6/12/17: I bought a second one b/c I wanted to see what happened with the first one and needed a new one anyway. In my updated opinion ,this is really the best game in town when it comes to powering Arduino projects.The reason I updated to five stars from two is that I found that it was the motor controller that was short circuiting. The problem was the in-line fuse (thermal auto-reset) was not reacting fast enough to the short allowing the short to affect the power supply. The…

My CPAP usually runs around 16 cm, so I put a lot of strain on a battery.I recently took my CPAP tent camping for two nights, so I brought two batteries.The first night it was 8 degrees Fahrenheit. I slept over ten hours that night, and the battery and CPAP were still going strong in the morning. The CPAP and battery were OUTSIDE of my sleeping bag (but inside the tent).The second night we had a heat wave of 20 degrees, and the second battery performed flawlessly just like the first one.These…

This is a high performing battery pack for its size. I needed a high wattage battery to replace a lead-acid battery in a portable searchlight. The previous battery was rated at 9Ah but was very heavy and the shelf life was awful. They needed replacing every 2-3 years. This is the first 12 volt Lithium ion battery pack I had come across with sufficient wattage to try. First it weighs less than half the lead-acid and is more compact. Second, the lead acid powered the light for about 20 minutes…

I purchased this item in July 2017. It is now March 2018 and it does not charge anymore. I really liked using this power pack to power my radio. While it worked it was great. Once it failed I thought this product is terrible. I contacted TalentCell Technology with my problem and they helped me troubleshoot it. Found out I had a bad power pack. They offered to replace it for me. Great news. I like the product but I like the customer service even better. THANK YOU TALENTCELL TECHNOLOGY. I will…

Bought it to power a telescope german equatorial mount (meade lxd-75). Tested it out and worked great, should power the scope for at least 10h with normal use (and appropriate cable to connect battery to scope was actually included in the package!).Bit confused about the indicator lights though. Plugged into the charger and it charged to four green led's overnight. Red LED did not switch off or change to green when charged completely as instructions suggested it would. Don't know if this is a…

I bought this to replace the battery tank on a telescope guidance system. It had to power 2 stepper motors for 4-6 hours of observing. Plenty of charge left over at the end of the night. This battery was 1/3 the cost of the power tank it replaced.

I bought this as a backup and camping battery for my ResMed S9 Elite CPAP machine. I've used it at home for 2 1/2 nights. I started with a full charge and did not use the humidifier or heated hose. Expiratory Pressure Relief (EPR) is enabled on my unit. The first night was for 6 1/2 hours. The indicator read 75% full. The second night was for 7 hours. The indicator read 50% full. It lasted about four hours the third night before the charge was depleted. So, the indicator is very much like a…
