Finally!  We receive requests all the time about this. Yes, it's an IPX68 SUBMERSIBLE USB battery pack line that is absolutely perfect for bikepacking applications. 

It's not some lame IPX67 with a flap from eBay or Amazon that keeps the dust and rain out of the USB ports when the flap is closed up but with the flap up and the USB plugs in, will quickly fill up with water and die if you attempt to use it in a rainstorm.

This is a truly submersible unit, one that will charge and charge your devices while its submerged in water. Why is this important? Rain. With this unit, you can safely run a cable from your kLite Dual USB charger to the Nitecore NPB1 / NPB2 / NPB4 and not worry if the battery pack is sequestered inside a waterproof bag. You can literally zip tie it to the handlebars right next to your dual USB charger and have at it during a monsoon.

I'm running an NPB1 mounted right on my BarYak aero bars, and keep it plugged into my kLite dual USB charger during the day--with no fear of it getting wet. Because I run with electronic navigation and like multiple redundancy paths, I keep an NPB4 deep in my frame bag along with a backup GPS for a zombie-apocalypse nothing works anymore and need to navigate my way back home scenario. It's the little things, people, that let you sleep soundly at night. 

Here are the cool features of these units:

    • IPX 68 Submersible - while you're charging!
    • Small size relative to power output - details in specs below
    • Light weight
    • Moderate battery storage level, allows you to carry multiple units for redundancy without seeming over the top with a mega battery that weighs more than a pound.
    • Super trick pop up zip tie stabilizers that allow you to zip tie your USB-A cords into place to prevent vibration-related issues. They're actually intended to connect to flashlight-type product offered by Nitecore, but zip tie it up, people.
    • Pass around charging - allows you to charge your devices when the battery is plugged into the dual USB charger and the device is plugged into the battery. It's not "pass through" charging like the Voltaic offers - the difference is that with pass around charging, if you stop riding, the charge coming to your device will also stop. With pass through charging, when you stop riding, the charge coming to your device will continue. This matters if you're trying to stop the infernal iPhone or Garmin "screen on / off" cycle every time the charging starts or stops. There is a positive here--the pass around charging is up to 20% more efficient than pass through charging - because the charge does not go through the battery, there is less power loss and battery degradation. 
    • Can quickly charge with QC 3.0 support and 18W of max output. 
    • Touch sensor power level display
    • Standard power input ports - NPB1/2 use micro-USB and the NPB4 has a micro-USB as well as a dual input / output USB-C port.
    • The internal lithium-ion batteries have a maximum theoretical storage of 5,000mAh (NPB1), 10,000mAh (NPB2), and 20,000 (NPB4), but the practical available energy of these unit are 3,250mAh at 5VDC (NPB1), 6,500mAh at 5VDC (NPB2), and 12,400mAh at 5VDC (NPB4). To put this amount of storage into context:
      • iPhone 12 storage:  2,775mAh
      • Wahoo Roam storage:  2,000mAh
      • Garmin 530 extra battery pack: 3,100mAh

Note - These two units are not "Always On" like the Voltaic Systems Units. Like most battery packs, they have an automatic shutoff when the current drops below 100mA. This can be important if you're going to be powering extremely low draw devices with this unit. It will power the eTrex line (confirmed with my eTrex 20) but not the kLite Qube. Suggest you plug the Qube into the dual USB charger and run the second line to your battery when riding in the daytime. 

Oh, one other awesome feature of the NPB4 only--it offers redundant charging options (Micro USB and USB-C) and will charge using USB-A or USB-C.  The NPB1/NPB4 combo is a formidable pairing for bikepacking!
