This little portable battery was the solution to all my portable battery needs. The price is a little steep, but in my opinion, it's worth it. Here are my thoughts. I was on the lookout for a 10k mah portable battery that would be very small because I needed it to be. I looked at multiple options from other companies and decided that all of them were too big for my needs. I had all but given up hope when I discovered the nimble champ. This little bad boy has a small form factor, 18W fast charging (i don't even know what that means but my phone says it's fast charging when it's plugged in), and a USB-C and USB-A port. All that and it's 10k mah, which is a great size for a portable battery. I've included pictures as well to help gauge the size. An Elmers glue stick for scale, if you will. I love this thing and I would buy it again if I needed one. 10/10 would recommend

I bought this product due to its compact size and I will say that I was highly impressed by it. The indicator lights allow you to easily tell how much power is remaining. It’s perfect for the person that needs a quick charge for their phone but doesn’t want to carry around a charger that it much larger than the phone itself. Highly recommend.

Small compact and easy to handle, I use it for work, I’m a meter reader and we have company phones to type in all the reading and when my battery gets low I just plug in Nibble and it charges quick and it’s not in the way. Great buy!

I bought this for a trip and had not used it until we had a power out. The battery on my phone was almost dead so I decided to try this, I was totally surprised, when I saw how quick my phone was charging!

This portable charger is awesome plus it made from recycle materials. Help the environment

Durable, fast charging, and long lasting. It is smaller than some other portable chargers but has some weight to it. I have purchased several more for family members.

I love that this charger is small and portable, as well as giving a quick charge -- and you can charge it quickly, too.

Battery chargers fairly quickly, is not too bulky, and keeps a charge for a good couple of hours

This is my 2nd purchase of this model battery. Two important things - the product and company are environmentally minded, offering a way to recycle your old battery, plus the product is made from recycled materials. Beyond this, the battery is strong, providing multiple recharge cycles for your phone without between battery recharged. Lastly, you can charge the battery, while it recharges the phone.

I was looking for exactly this size and light, good quality... very good! I happy to get it!!

Charges fast and has a good capacity. It's heavy, but it seems durable.

Easy to charge, multiple ports, light and compact. Long lasting charge.

Takes a while to charge but it is worth it takes forever to die and charges pretty fast. I've had mine for about 3 months now and no problems at all. I would definitely give this to somebody if I didn't love it so much.

I love this charger. It fast charges, and can charge my phone to full several times before it needs to be recharged again, just as it advertised. I take it with me everywhere.

wanted a charger that was corded and not damaging to environment. bonus was its the exsact same color as my water bottle

This little charger is extremely light and portable. It’s very easy to use. Love it and have recommended it to others already :-)

Can’t say enough about this charger. Charges fast. Charged my phone twice and still have 50% power.

Best portable charger… fast charge & compact.. great Christmas gifts!

Best portable charger…fast charge & nice and portable!!

Like all the other reviews say, it charges my device pretty fast. It has four charging lights. A full charged phone takes half of the charging capacity on the portable. The portable does take a significant amount of time to charge itself. I like it though. Good purchase. It’s small and not heavy.
