Tldr: love batteries, great feature in a compact form. Buy a faster charger over 100ah. Customer service is the reason I wrote this reviewSo I have bought 2 batteries (120ah) and I love both! I used to buy power stations but never again. I've had 1 in use for a month now and am ready to make a report. All of the ports make it super easy to connect anything and everything. They add a ton of versatility and value! They included an Anderson connector with both batteries that I could attach to my existing wiring. The second battery also included an LD20 connector that I could attach.The 10 amp charger they send is not great however. 12 hours to recharge a dead battery is painful. Buying a 20-30 amp charger (make sure it's for lifepo4 batteries) if you have a 100-200ah battery makes life a lot easier. I do wish it were included for the price point but they're cheap enough.The battery had slightly different screens. They display the same information but one is more visible in the day and can be read from more of an angle that the other. Neither is a problem just something to be aware of.The instruction tell you that if the battery is submerged you can take it apart to dry it and repair it as needed. Not only is it a repairable device, they encourage it! I haven't taken mine apart yet (just 2 small bolts) but I get the feeling they would be as helpful as they could if I needed to in the future.CUSTOMER SERVICE 11/10I had some questions with the first and they responded very quickly. Their customer service team is informed, efficient, and friendly.The second battery did have a defective USB port BUT I let them know I had a problem and within 19 MINUTES they were offering solutions. They offered me a replacement or fair compensation to purchase an adapter of my own and allowed me to decide.Can we all take a minute and acknowledge how incredible it is to get answers that fast!!! I've waited for 2 weeks for a big name power station company to reach back out to me when I had questions. I wasn't even expecting a response the same day let alone in the same TV time slot!!! I could not be more impressed by their dedication to their customers. They also let me know that going forward they will set a benchmark of 30 minutes or less for replies during business hours and I think that is a commendable goal.I know it was long but I wanted to give my full review of the company and the product. I would gladly give them my money again

Purchased this for my new Saturn 10 feet inflatable boat with Watersnake 34LB thrust trolling motor. The motor was rated to run for 60 AMPH but this battery was doubling that for longer run time. It was great to see high AMP battery option included as trolling ready waterproof package with charger. The battery arrived well packed with all accessories. Probably it was precharged so didn't take much time to fully charge. All the accessories and input/output ports worked as expected. The quality of casing and internal components looked very well. The included ports are similar or better than most of the high end battery boxes out there hence you save a lot of money in buying this separately. It is heavy but size is manageable for a small boat or kayak based applications. I have taken it for trolling at full throttle speed for almost 1.5/2 hrs and the battery charge did not deplete more than 25%. It says in the product description that the battery usage % may not be accurate so it is tough to know true usage. This is the only knock on this model. Hindsight I think I should have purchased model with bluetooth based battery capacity tracking app. I will try this out for a full day of operation to know if I am getting all advertised AMH and provide an update. I have added a 60 AMP circuit breaker and created a custom Anderson connection to connect to Trolling motor using provided connector. So far this has been a great experience. Buy with confidence.

Perfect for my kayak! Not too heavy and perfect for my trolling motor. Will also be great for camping trips.

This battery works incredibly well for me, I use daily to power a swimming pool cleaning device. I like the different power ports that it has. The company is very good to work with.

Owned for almost a year now. Will power a trolling motor for hours, powered lights, fans and charged our phones through the power outages from hurricane Helene. Has came in handy many times. Recently both the usb slots stopped working which was one of the main reasons I chose this particular battery, hence why it’s getting 3 stars instead of 5.

The Li battery is "as advertised" AH capacity. The maximum discharge rate of 100A also appears to be correct. It should not be used to start a car, 250A, or run a heavy duty winch with about the same current draw. It is VERY GOOD if used below its max rating. More robust internal wiring could solve this performance condition. It takes a long time to "fully charge" from "completely discharged" with its own low amp charger, about 10 hrs. -120AH. When I hooked a more powerful charger up, the battery gauge permanently quit showing the "Percent Charge." Not a really big problem as the gauge continued to show voltage, which is an accurate indicator, provided you know its maximum and minimum voltage. The case, Pelican Box modified, is very good with great connectors and is water tight. All-in-all a good compact storage unit if used within its parameters, but I haven't hooked it up to my solar charging system yet.

Works perfect shipped perfect and has been perfect for my ham radio portable. And running electronics on my kayak and other electronics not around a plug. Great portable power options
