When you are counting every single ounce in your backpack, a heavy 20,000mAh power station is the first thing to get left behind at the trailhead. If you are going on a quick weekend trip or a long day hike, you only need enough juice for a single smartphone charge to handle GPS routing and emergency calls.
This brings us to two of the most popular minimalist chargers on the market: the Anker 511 (PowerCore Fusion 5K) and the Goal Zero Flip 12.
Anker 511 vs Goal Zero Flip 12 for hiking: The Anker 511 is the superior choice for digital nomads and weekend travelers due to its faster 20W USB-C output and 5000mAh capacity. However, for strict ultralight backpackers, the Goal Zero Flip 12 wins out. It weighs just 2.5 ounces compared to the Anker’s 6 ounces, providing exactly enough emergency power without the extra bulk.
Both of these devices approach portable power in completely different ways. Here is the breakdown of which charger belongs in your pack.
- Built-In Lightning Connector: Hassle-free direct plug for iPhone, no cables needed, instantly delivers reliable 12W power when charging on the go, perfect for travel, work, or emergencies.
- Fast 12W Output: Optimized PowerIQ charging for iPhone and iPad ensures speedy and safe power delivery, keeping your phone ready without overheating or slow charging interruptions.
- Compact & Lightweight: Pocket-sized 5000mAh external battery fits easily in bags or palm, ideal for everyday carry, flights, road trips, or quick top-ups during busy schedules.
The Anker 511 (PowerCore Fusion 5K): The Hybrid Powerhouse
The Anker 511 is technically a “hybrid” charger. It features built-in folding AC wall prongs, meaning it acts as both your standard wall charging block and a portable battery.
The Specs:
- Capacity: 5,000mAh (Roughly 1 to 1.5 full smartphone charges)
- Weight: 6 oz (170g)
- Output: 20W USB-C (Power Delivery)
- Input: Built-in AC wall prongs
Why it works for hiking:
If your hike is part of a larger travel itinerary, the Anker 511 eliminates the need to carry a separate wall adapter. You can plug it directly into a hostel or coffee shop wall to charge your phone. Once your phone is at 100%, the Anker automatically fills its own internal 5,000mAh battery. The 20W output is incredibly fast, capable of getting a dead phone to 50% in roughly 30 minutes.
The downside:
At 6 ounces, it is relatively heavy for only providing 5,000mAh. The built-in wall prongs, while convenient in a city, are completely useless dead weight when you are 10 miles deep into the wilderness.

The Goal Zero Flip 12: The Bare-Minimum Backup
Goal Zero is a legendary name in the off-grid community, and the Flip 12 is their smallest offering. It is designed to be purely an emergency backup.
The Specs:
- Capacity: 3,350mAh (Roughly 75% to 1 full smartphone charge)
- Weight: 2.5 oz (70g)
- Output: 5W USB-A
- Input: Built-in flip-out USB-A plug
Why it works for hiking:
The Flip 12 is the definition of ultralight. At just 2.5 ounces, it weighs less than a standard Clif Bar. You can drop it into the brain of your backpack and completely forget it is there until an emergency strikes. Instead of wall prongs, it features a clever “flip-out” USB-A tip, allowing you to plug it directly into a solar panel (like the Goal Zero Nomad) or a computer port to recharge without needing an extra input cable.
The downside:
The 5W output is incredibly slow by modern standards. It will trickle-charge your phone, meaning you will need to leave your device plugged in for a few hours to see a meaningful difference. Furthermore, the 3,350mAh capacity is not enough to fully charge massive modern phones like an iPhone 15 Pro Max from zero to a hundred.
The Gadget Earth Verdict: Which Should You Pack?
Choose the Anker 511 if: You are a hybrid traveler. If you are bouncing between airports, coffee shops, and day hikes, the Anker 511 is the ultimate all-in-one travel companion. The 20W fast-charging is a lifesaver when you only have 20 minutes near an outlet before catching a train.
Choose the Goal Zero Flip 12 if: You are an ultralight hiker heading off the grid for a night or two. If your phone lives in airplane mode and you only need a physical safety net for your GPS apps or emergency calls, the Flip 12 gives you the power you need at half the weight of the Anker.
