NASTIMA 12V 6000mAh Lithium Iron Phosphate Power Bank with 14.6V 1.5A Charger, 2000 Cycles 12.8V 6AH LiFePo4 Rechargeable Battery with DC 12V 9V and 5V USB Output for LED Strip, CCTV Camera, Mobile

Very happy does everything I want it for

The power out cable is very short, you better be aware how will you use it. The standard DC5525 cable you purchased here may not fit, due to the central pin on the 12v port has a wider head. The battery itself works well. I hope the manufacturer will fix this issue. At least provide a reasonable long cable for power output.Customer service is very decent and quick responding to my issue.

Does not maintain 12v output. This drops to 10v or less, in minutes.

Defective unit I guess… Does not maintain 12v output. This drops to 10v or less, in minutes. And does not recharge to full capacity.

I got this 12V power bank to run some LED lights on. On one hand, it performs pretty well for its rated capacity, but if you have a full 5A load on it, it will only last for about an hour. I ran a load test on it and the no-load voltage is 13.5V on the 12V port. Putting a max rated 5A load on it drops the voltage down to 12V though. At that amperage, it held right at 12V for about 50 minutes, then started dropping pretty quickly over the next 20 minutes. At 70 minutes, the battery shut itself off when it got down to about 10V. Overall, I got about 5.9Ah/70Wh out of it, which is reasonably close to its rated capacity. The battery did get a little bit warm when pulling 5 amps out of it for over an hour, but it doesn't get hot at all.The 4-LED meter on this battery is almost useless. With the 4 LEDs on, you can't tell if it's fully charged or just kind of charged. Then, when the battery is completely depleted at 10V, it still shows 1-1/2 LEDs on. After plugging it back in to charge, it will already show 3 LEDs after just 5 minutes of being plugged in and 4 lights on after about 20 minutes. If I unplug the charger at that point, there are then only 3 LEDs lit up.The power switch is listed as an Input/Output Switch, but really just means OFF or ON. None of the ports have power on them when the switch is off. But because the same 12V port is used for both 12V output and for also charging the battery, I don't know what happens when you have it plugged into the included charger and then flip the switch to the ON position. Hopefully it handles that situation well, but I wasn't willing to test it out. No doubt it will happen accidentally at some point though.I think this power bank provides a reasonable value for the price. And as long as you take into account the actual capacity of this battery and don't expect more out of it, it performs pretty close to what it is rated at. Having the 9V and 5V USB-A ports on it in addition to the 12V port are a bonus as well. I do wish it came with a bag or case to keep the battery and included accessories together though.

I like having 5v USB, 9v, and 12v output all from one battery. The charger does have the correct plug for the US despite the pictures showing an EU plug. My one real concern with this battery is the charging behavior. As soon as it’s plugged in the charge indicator lights sure a full charge and do not change as the battery recharges. The only indicator of the actual charge status is the red/green light on the charger. Not sure if this is a problem or a feature.

This powebank works with Medela pump. 2 days after I got it we lost electricity for a day and this came in handy.
