Reliable power for chair and phone

Chris Butchkoski—December 12, 2025

I’ve been using the 5V2A 20000mAh Battery Pack mainly with my heated folding chair and as a backup for my phone, and it’s been excellent. The durability stands out compared to other packs ive gotten off amazon in the past. I don’t worry about tossing it in a bag or using it outdoors (Assuming it isn't raining). The charge lasts a long time, easily powering my chair through extended use during a movie or game and still having enough left to top off my phone. What I really like is that it’s not bulky, so it doesn’t get in the way or feel heavy. For me, it’s been well worth the money because it’s dependable, long-lasting, and versatile enough to handle everything I need. Read more

Works as expected

Rick lo—January 1, 2026

Works as of now. Looks almost identical to an old one(the reason I got this replacement) I had which I was only able to charge once then didnt work anymore so hopefully this one is good. The battery seems to last I got it at 3 bars out of 4 I have used it for hours on low and im still at 3 bars. Read more

The capacity of the battery speaks volumes of the quality

nathaniel—December 4, 2025

I bought this battery pack about a year ago, to power a heated jacket. The capacity of the battery speaks volumes of the quality. The size of the battery is perfect. The only down fall is the weight. It's heavy for its size. However, I am very pleased with this battery. Not to mention the value for the money. Read more

Battery can last more than 12 hours on medium heated vest setting

mamafirebird—December 1, 2024

I purchased this battery because I knew I’d need a backup for the one already in my heated vest. It takes quite a long time to fully charge (overnight is best), but it also can keep my vest toasty warm for a whole day out in the cold. My one concern is the weight - it’s quite heavy, and because it’s bigger than a battery with less storage capacity, it essentially means you can’t put much into the left hand outside pocket because there’s no room. Highly recommended! Read more
