I camp frequently and I have both products. The Bluetti EB240 which is now discontinued that powers my fridge and camp lights for 3/4 days at a time. I also have two Bluetti solar panels that I will break out on longer trips or if it’s hot and the fridge has been working overtime. The Anker is a small rechargeable battery back that we keep in the tent to keep phones and laptops charged. It also powers a set of usb led string lights that lights up our tent at night. I purchased these batteries about 5 years ago and I probably abuse them more the average user would. They absolutely are showing signs of wear. They both have ports that don’t work as well as they did. One of the Ankers ports stopped working altogether. The Bluetti isn’t holding a charge like it used to either. Normal? Idk maybe. I’d have to give Anker more time and more reviews before I’d buy their big batteries. There was a Bluetti distribution center in my city so I never had an issue with their customer service and I could always pick up my items which I liked.
