It took over a day to charge the power bank itself and when trying to charge my phone (Galaxy S6 Edge), it loses battery when in use

It’s a very good battery and the low price is an extra bonus

Although the portable battery isn't the best on the market, it's the best bang for your buck

I know someone who owns Aibocn Power Bank 10,000mAh External Battery Charger with Backup Flashlight - Upgraded and that is able to Fast Charge on the Galaxy S7 so this brand can make good battery packs; not sure if mine is defected or just not compatible.

Good size, great battery power.

Best affordable portable battery ever purchased

This little battery is great

This battery is half drained after 1 day of use.

Anybody else has the same issue or my battery is defective?

I have been looking for a battery Bank this powerful for a long time in the price is very reasonable

I like this battery enough

This is a very well built battery pack and will power a low current load device without auto power down.

It took less than 2.75 hours to fully charge the fully depleted 3220mAh battery of my Samsung

It still got warm but no where near as hot as it was
