    Hello I just want to share my experience. I bought the Xtorm AL390 a couple months ago. It has a little less capacity than this LifePower battery (18’000 mAh) for the same price. At first I was quite satisfied because I could finally charge my laptop on the go but after using it for a couple of days I started noticing its flaws. The Xtorm gets pretty hot when you use it and there is a fan inside for this issue, but the fan is really noisy. So instead of solving the heat issue they actually made it worse, plus I also noticed a weird smell coming from it. Then I discovered LifePower on Instagram. I’ve been using this A2 S for two weeks now and I’m super happy with it! It works even longer than expected. I’m very happy!

    Hey Lifepowr, I found you through some digital nomad hashtags on Instagram. I’ve been a digital nomad since 8 months now, and have been looking for the right battery pack to power my laptop and camera. I was hesitant to buy from large companies such as Goal Zero and ChargeTech for many reasons. So happy I found you guys! I just ordered an A2 L, haven’t received it yet but I have high expectations. I’ll post another review soon!

    The only thing I don’t understand is why this battery pack looks identical to the larger one, while it has way less capacity. I would prefer a smaller case with a smaller capacity! But nonetheless a good product. Does what it says.

    Only one USB port is disappointing. But fair is fair, that shouldn’t stop you from getting this product, it’s the best external battery I’ve found so far. I’m hoping on a next version with more outlets though……..

    Good product, less capacity than the other A2’s but still very powerful for this price! Plus the AC outlet is groundbreaking.
