Took the Nextcore640 camping last weekend and it was surprisingly useful. We used it for the lights, phones, and a small coffee maker in the morning. It didn’t take up much room in the car either. Nice little addition to our camping gear.

We had a short power outage at home, and this came in handy for keeping our phones and a few essentials running. I also like that it’s small enough to move around easily. I originally bought it for outdoor use, but I can already see myself using it around the house quite a bit.

Been using this mainly for e-bike trips and weekend rides. It’s pretty handy for topping up my phone, lights, and even giving a bit of charge to my e-bike setup during long stops. Build feels solid and it’s easy to carry along with my bike gear, which I like. The screen is clear and it’s straightforward to use on the go.

Great little power station. Compact, lightweight, and perfect for camping or everyday backup power.

I’ve been using the Nextcore640 for weekend camping trips and it has been really convenient. It’s compact enough to bring along without taking up too much space, but still has enough power for phones, lights, laptops, and other small devices. The display is easy to read and the setup is straightforward.

I like that it is practical to move around without making portable power feel like.

The controls are straightforward, and it has been convenient to have portable power available when.

This has become one of my favorite pieces of camping gear. I can keep my phone, lights, camera equipment, and other electronics powered without having to rely on campground outlets. It’s easy to move around and doesn’t take up much room in the car. The fast charging is a big plus, although I wish the battery could last a little longer on heavier use. Overall, a really handy power station for camping and weekend trips.

This is a really useful addition to my e-bike setup. I like having extra power available when I’m out riding for the day, especially when there isn’t a convenient place to charge. The 640Wh capacity gives me plenty of flexibility, and the unit is portable enough to take along in the car for longer trips.

I was looking for something that could provide backup power without being too large or heavy, and the Nextcore640 fits that role well. It has plenty of ports for charging several devices at once, and I really like the LiFePO4 battery design. It feels like a practical power station for both outdoor trips and home backup.

Lets me ride farther without worrying about battery life.

I often spend the whole day riding, and having this portable power station means I can top off my e-bike battery during breaks. It gives me much more flexibility on longer trips.

I bought the Kingbull NextCore 640 mainly to recharge my e-bike during long rides. It gives me the confidence to ride farther without worrying about finding an outlet. It's easy to carry in my truck when heading out for weekend adventures.

It’s nice to have back up resources for power. Liked it so much I bought another. A backup for the backup. Then bought solar panels to charge. Charge my phone, watch, battery for my e-bike, etc. If we lose power in the summer, I have a fan to plug in. Winter, a ceramic heater. What’s not to like?!

Gives me extra confidence on long trips.

I recently took my Kingbull e-bike on a camping trip. The NextCore 640 made it easy to recharge the battery while we relaxed at the campsite. It worked exactly as I hoped.

Leaving this review on this power pack because bought this for camping trip I will be doing so testing the operation of this pack. Check out solar panels for packs found 100 watts panel can charge 600 watts pack within 2 to 3 hours ran this pack down to 30% power charge great to 100% same test plug in the house charge faster did what the specs says. The number one reason I wanted this pack is the metal case of the pack it can take a beating of camping small and compact compare to other pack plastic case.
