Anker 337 Power Bank (26,800mAh) Review: A Serious Charger for Serious Trips
TestedYour phone hits 20% before lunch. You've got a flight, a road trip, or a weekend off-grid coming up, and a phone-sized charger isn't going to cut it. That's the gap the Anker 337 is built to fill — a high-capacity power bank for people who want to charge multiple devices without hunting for an outlet. At $79.99, it sits near the top of what most people should reasonably pay for a portable charger, so it needs to earn that price.
What It Is
The Anker 337 is a 26,800mAh portable battery pack with USB-C Power Delivery up to 60W. In plain terms: it's a large-capacity charger that can top up a phone several times over, or push enough power to charge a laptop that supports USB-C charging. It's part of Anker's well-established lineup, and with over 12,500 ratings averaging 4.6 stars, this isn't a niche gamble — a lot of people have already put it through real-world use.
Who It's For
This isn't for someone who just needs their phone to survive a commute — a smaller, cheaper bank handles that better and cheaper. The 337 is built for:
- Frequent travelers charging a phone, tablet, and maybe a Switch or laptop on the same trip
- Remote workers or digital nomads without reliable outlet access
- Anyone prepping for outdoor trips, long flights, or power outages where a phone-only charger won't cut it
If your charging needs are modest, this is more capacity — and bulk — than you need. But if you've ever run every device dry at the same time, this is built for exactly that problem.
Key Features & Specs
- 26,800mAh capacity — roughly 4-5 full phone charges, depending on your device
- 60W USB-C Power Delivery — fast enough for many laptops, not just phones
- Dual output ports — charge two devices at once without one starving the other
- Travel-friendly size — large-capacity banks tend to turn into bricks, but Anker keeps this manageable enough for a bag or backpack
- Anker build quality — a brand with a long track record here, which matters when you're trusting it with a $1,000 phone
Pros
- High capacity means fewer recharges and more peace of mind on multi-day trips
- 60W PD output is genuinely useful for laptops, not just a spec-sheet bullet
- Dual-device charging works well, without noticeably throttling either port
- Strong, consistent feedback across a large review base
Cons
- Heavier and bulkier than basic 10000mAh banks — not ideal for minimalist EDC
- At $79.99, it's near the top of the category's price range, so it's not an impulse buy
- Overkill if you only need occasional phone top-ups
The Anker 337 isn't chasing the lowest price — it's built to be the charger you stop worrying about on a big trip. $79.99 is a real cost for this category, but it buys genuine capacity, real fast-charging power, and a reliability track record that's hard to fake across 12,500+ reviews. For heavy travelers or anyone charging more than a phone, it's worth the money. For everyone else, it's more than you need.
