Power Miser: holds a lot of power; doesn't want to share it

JPK - 5 days ago, Verified purchaser
This works great and seems to hold a lot of “juice” for my electronics. However, the speed with which it charges AND the speed with which it provides a charge are both INCREDIBLY SLOOOOOW. Painfully slow. Agonizingly slow. When I needed to recharge my phone while walking around Seattle, I had to leave it plugged in the whole time. Even when I wasn’t using my phone, it charged so slowly that after an hour, my phone’s battery level had gone up barely 10%. I should say that it charged my phone entirely at one point and the power bank’s own level went down minimally. So in that sense, it’s a great product. But if you’re looking for something that can charge rapidly so you can unplug right away, this isn’t the one.
Great to be prepared!

I like how it keeps a good charge but it takes almost a full 24 hours to charge it to 100%. I don’t like that here is not any solar panels on it to charge the device another way. It is heavy so careful with it.

Be warned that this charges extremely slow. In 2025, nobody should be buying slow power banks. 10 years ago, you could probably forgive this, but certainly not in the new year.

This thing works but it's heavy. It's definitely a carry in a backpack device more than a carry on a purse device. It is a powerhouse. But not one that meets TSA regulations for taking a battery on a plane. And I wish that had been more visible on the packaging

Of course after I bought this “on sale” in person for $33 it’s cheaper online for a regular price.. With that said, this thing has come in handy for me. Long dance competition days with little access to wall outlets, I’m able to plug my phone, tablet, or kindle in from my bag. It holds several charges and works great. Cons: it takes a while to charge the power bank itself, and it’s fairly bulky/heavy. But it does last a good amount of time and has been a lifesaver when out and about, so overall I love it!

It’s heavy, but I knew that when I purchased it. The problem is that it fails… A LOT! Support says it needs to be plugged in to reset it. That does me no good when I don’t have power. Which is why I purchased a battery pack to begin with.

[This review was collected as part of a promotion.] This charger is slim, sleek, and compact, just a bit larger than my iPhone itself, it fits perfectly into my handbag. My only complaint is that it is a bit heavy, but that is to be expected in charger with this much charging capacity. I’ve used it for a bit over a month now, and It has worked well for me. It charges quickly and I can fully charge my phone multiple times with it before I need to recharge it. I often use Uber/lyft when I go out, and I feel secure in that I can always order my ride regardless of how much I use my phone.

[This review was collected as part of a promotion.] I always carry a portable charger with me and this definitely lasted me the whole day, it even has some leftover. I can put this in my work bag and know that I don’t have to worry about my phone dying. The only downside is that it is quite larger than I expected. I can’t carry it for a night out due to it being too large however it does fit in my work bag.
