Portable Battery Bank To Charge Laptop

[Lithium-Ion] I love this thing as i can plug it into an external battery bank and charge my batteries while theyre in my case.

[0.095 lb] I've been using this as a multi-purpose unit from camera battery to portable power bank for recharging my phone and other USB devices. It's quite compact for 98Wh and pretty great price too.

[USB: 5 V / 2 A] I have two of these chargers. They are well built and powerful. However, that power comes with a string attached - if you want to rapidly charge a Mavic 3 battery the input voltage has to be greater than produced by a typical full charged 12 volt battery. DJI tells us this - stating that we should use the charger only with the car running. However, the specifications state that the input voltage needs to be 12.7 - 16 volts DC. Which led me to assume the 540 amp hour 12 volt battery bank in our expedition truck, which delivers 12.8 - 12.9 volts when fully charged would be sufficient. That is not the case - I need to have somewhere between 13.1 and 14,1 volts minimum (closer to 14.1 I suspect) for the rapid charger to work with an Mavic 3 battery. I can work with that as long as I charge during the day with solar input raising the voltage of the battery bank or when the truck's engine is running. This charger will work fine charging a Mavic Mini 2 battery bank with the supply at 12.8 (perhaps lower as well - I've not tried that). It might also charge the Mavic 3 battery via the USB 2 - USB 3 outlet but at 10 watts I'd presume that would considerably slower than the 65 watts possible with USB 3 - USB 3 outlet. I have not tried my car chargers with large portable power banks like those from Goal Zero or Jackery. I suspect the same restraints would apply - rapid USB 3 to USB 3 of a Mavic 3 battery will require solar or other supplemental input. Again - not a problem if you plan for that. I've given the charger 5 stars because it is great and works well as long as one respects the design parameters.

[5 VDC] This is my 5th nitecore charger - 2 others have been stolen. Easy to use and able to charge from a battery bank on the go and in the car. Perfect for travel!

[1.25 Hour] I've taken this power bank on a few trips, including one international trip. I bought it as a backup for my laptop on long flights since the battery life on my laptop is not good (it's optimized for performance, not battery life). No problems powering my laptop, and it's charged up my phone and tablet a few times also. Its main drawback is that it's a little heavy. But it's worth carrying around. Comes with a nice microfiber bag to protect it when not in use. Make sure you keep this in your carry-on luggage. Most airlines will not allow you to put lithium batteries in checked luggage.

[Metal] Works great and I can charge it with a power bank!

[0.1 lb] i use it with a Battery Bank and it work's Fine

[14.8 VDC] I have a four bank swittronix vmount charger and this is way more portable, comparable to the redcharger.
