Goal Zero Flip 30, Charcoal

Would have 5 well-earned stars if it wasn't for the painful flip out USB input connection - as others have said, you'll soon want to use a USB extension lead for a better connection.But, if you want less hassle, buy the Venture 30 - for twice the price!Pros: great battery capacity for the price, feels like a premium product, great value, add a Nomad panel for limitless, zero carbon phone and gadget charging.Cons: that flip out connection is clever but spoils the product.

Brilliant kit..

Lo uso da oltre un anno... Continua a funzionare molto bene.

Totally familiar with this product line, as well as the Goal Zero family of solar/rechargeable products. Durable, has a built USB charger and a single USB port for cable charging. Comes in a variety of colors, able to charge an iPhone 5/6/7 or a Samsung 6/7/8 approximately 1.5 times. Compact, design holds a decent charge. Pressing on the USB charger displays a series of blue dots showing the battery capacity. RECOMMEND: buy a couple (I did & more over the years).

its a little heavy... But it charged by completely dead cell phone 3 time on a single charge

Good form factor and decent charging speed on a Nexus 5. I knocked off points because the male USB plug for actually charging this device is inconvenient. I generally charge via a PC and it pretty much requires a female/male extension cable which most folk don't have lying around

These are great. I have 4 now. Also have the base to charge two at a time. More expensive than some batteries but long lasting.
