Need a charge?

Oh goodness, this really checks all the boxes, powerbank-wise.

It’s pretty. (Not all of them are pretty.)

It’s slim and compact. (Not all of them are slim and compact.)

And for a serious device like this, you really want something that delivers at least 10,000 mAh, and…holy cow this one is double that. (Not all of them are double that.)

This is a genuinely premium powerbank from Griffin, is what we’re saying. (We can probably quit with the parentheses now.)

With 20,000 mAh on board, you’re going to be able to do more than just nudge your phone out of low power mode. You’ll be able to charge that thing from 0 to 100 percent and then some. This means that if you have an extended power need, you’re covered. And if you just want to be able to top off with a bit of charge here and there without having to recharge the bank itself, that’s also fine.

Plus at just twelve bucks, you’re really talking about a bargain-priced little lifesaver here.

Unless you have something exactly as good as this already, probably just grab one. (And even if you do, maybe grab another. Last parentheses, we promise.)

Charging

I need this charger and thought it would help when I’m on the go. I wanted to carry it in my purse. I will not be carrying this inside my purse. I found it too HEAVY to carry. I will look for another charger that will fit my purse without the heavy weight.

Too Heavy

I purchased 3 of these because I thought it was a good price, but I can see why you are selling them so cheap. They are heavy and bulky. No one wants to carry this extra weight. They will be good for a day in the park and you just throw one in a bag with other stuff, but they are not convenient.

This power bank is not for Androids phones. It does not fit them. This should have been disclosed in the advertisement. Now I have to send it back for a refund.

  1. Sharper Image by Vornado AXIS 12 Desktop USB Airbar Tower Fan
    ★ ★ ★ ★ ★
    Not what I would expect from Sharper Image

    The fan doesn't blow out very hard and also I thought the USB was to recharge it but apparently if it's not plugged in it doesn't work, which limits the places I can put the fan

  2. 2-Pack: TUSHY Ottoman Go Toilet Stool
    ★ ★ ★ ★ ★
    Nice!

    I should have read the instructions before assembling but easy to fix. Wife and I love these and they replace a clunky step stool we were using.

  3. KeySmart ALLTUL 16-in-1 Keychain Multi-Tool
    ★ ★ ★ ★ ★
    Alltool expected it to be better

    It wasn't as good a fit on KeySmart (too thick). The tool that it replaced fit better.
