Goal Zero Sherpa 40 Power Bank – 12,000mAh Slim USB-C Charger with Included Cables

Slides into a jacket pocket without the bulk of my old power bank. Charged my phone nearly three times on one fill. The included cables are a nice bonus so I'm not hunting for cords.

Took this on a two-week trip overseas and it never let me down. Slim enough for a carry-on, charges fast on USB-C, and the 4.8A combined output means my wife and I can both top up at once. Very satisfied.

12,000mAh in this form factor is genuinely impressive. Charges my iPhone fine but refilling the bank itself takes a few hours. For the sale price with three cables included, hard to beat though.

Bought this after my cheap gas-station brick died for the third time. Night and day difference. The metal-ish finish feels premium, it fits in my laptop sleeve pocket, and I've charged my phone, earbuds, and a friend's tablet simultaneously without it getting hot. The included Lightning cable alone saves me $15.

Reliable, slim, well made. The four indicator LEDs are easy to read. Would give five stars if it supported faster input charging, but output performance is excellent.

It charges devices reliably and is nicely compact. My gripe is that 12,000mAh translates to about two full phone charges in real-world use, less than the math suggests. Also no carrying pouch included. It's a fine budget option at half price, just temper expectations.

Got one for myself and liked it so much I bought two for my kids heading back to school. They love that the cables are included and that it fits in small bag pockets. Charges everything from phones to handheld game consoles.
