The best anker powercore 26800 vs anker 737 for your situation depends on how you plan to use it and where.

Last Updated: June 2026 | Written by the JoltCell Editorial Team

I carried both the Anker PowerCore 26800 and the Anker 737 Power Bank in the same backpack for three weeks straight. Same flights, same coffee shops, same kitchen counter at the end of the night. The goal was simple: figure out, in the anker powercore 26800 vs anker 737 debate, which one actually deserves a spot in your bag in 2026.

Here's what I found out — and it surprised me.

Quick Answer: Which Anker Power Bank Wins?

• Buy the Anker 737 if you charge a laptop, a Steam Deck, or need fast top-ups on the go. The 140W USB-C output is the real story.
• Buy the PowerCore 26800 if you only charge phones and tablets, hate touching firmware, and want the cheapest reliable 26,800mAh brick on the market.
• Buy neither if you're going camping for more than a weekend — you actually want a small power station instead, and I'll point you to one below.

Quick Picks Comparison Table

How We Tested

I ran both power banks through the same gauntlet over 21 days:

• Charge cycle test — fully drained and recharged each unit five times, logging input wattage with a USB-C power meter.
• Device test — charged an iPhone 15 Pro, a Pixel 8, a MacBook Air M2, a Steam Deck OLED, and an iPad Pro 11".
• Heat test — ran each at full output for 30 minutes in a 75F room and measured surface temperature with an IR thermometer.
• Travel test — both went through TSA at SFO and LAX. No issues with either; both are under the 100Wh airline limit.
• Drop test — accidental, not planned. The 737 took a 3-foot drop onto hardwood. More on that later.

Design & Build Quality

The PowerCore 26800 looks like a thick black bar of soap. Matte plastic, slightly textured, no screen, just four white LED dots on the side. It feels cheap-ish in the hand, but in a way I respect — you're not paying for finish, you're paying for cells. After three weeks in my bag, the only sign of use is a small scuff on one corner.

The Anker 737 is a different animal. Aluminum-feel shell, rounded corners, and a tiny digital screen on the front that shows watt input/output, remaining capacity in minutes, and battery percentage. The first time I plugged my MacBook into it and watched it pull 96W in real time, I genuinely smiled. That screen is the feature.

That said, the 737 dropped off my standing desk on day 9. Three feet, hardwood floor. The screen still works, but there's a hairline crack in the corner of the housing. Cosmetic only, but it tells me the alloy shell isn't as tank-like as it looks.

Winner: Anker 737 — the digital display alone is worth it, even with the cosmetic ding.

Features & Functionality

This is where the anker 737 review verdict really separates from the PowerCore 26800.

The PowerCore 26800 has three USB-A ports. That's it. No USB-C, no Power Delivery, no quick charge protocols beyond Anker's older PowerIQ. You plug in a phone, it charges at maybe 10-12W. Plug in three phones, the total still caps around 15W spread across them. It is a battery. It moves electrons. Nothing else.

The Anker 737 has two USB-C ports and one USB-A. The headline USB-C port pushes 140W of USB-C PD 3.1 — enough to fast-charge a 16-inch MacBook Pro, a Steam Deck, or a Nintendo Switch at full speed. The second USB-C handles up to 100W. You can also recharge the 737 itself at 140W, meaning a full top-up in 58 minutes flat on my testing.

The PowerCore 26800 takes 6 hours and 31 minutes to recharge over its Micro-USB input. I timed it because I didn't believe the spec sheet. The spec sheet was honest.

Winner: Anker 737 — and it's not close.

Performance

For phones and tablets, both work fine. I got roughly 5.5 full iPhone 15 Pro charges from the PowerCore 26800 and 4.8 full charges from the 737 — the 737's higher voltage conversion overhead eats a little efficiency, but it has lower nominal capacity too.

For laptops, the gap is brutal. The PowerCore 26800 cannot charge a MacBook Air M2 in any meaningful way — it'll trickle, but the laptop drains faster than it gains under any real workload. The 737 charged the MacBook Air from 18% to 92% in about an hour and a half while I was working in a coffee shop near SFO.

For the Steam Deck OLED, the 737 gave me about 2.6 full handheld charges. That's a flight from SF to JFK with juice to spare. The PowerCore 26800 simply can't deliver the wattage the Deck wants.

Heat? The PowerCore stayed cool — peaked at 91F surface temp. The 737, when pushing 140W into the MacBook, hit 112F on the side closest to the USB-C port. Hot but not alarming.

Winner: Anker 737 for laptops and high-draw devices. Winner: PowerCore 26800 for raw phone-charge count.

Price & Value

The PowerCore 26800 sells for around $59 in June 2026. The Anker 737 hovers around $129, occasionally dipping to $109 during Prime events. That's more than double.

Here's how I think about value, after three weeks: if you only own a phone and maybe an iPad, paying double for the 737 is silly. The PowerCore 26800 will do the job for years. If you own a laptop or a handheld and travel even semi-frequently, the 737 pays for itself the first time you skip a hunt for an airport outlet.

Winner: Anker PowerCore 26800 — pure dollar-per-watt-hour, nothing touches it at this price.

Customer Reviews Summary

The PowerCore 26800 has been around for years and carries one of the highest review counts of any power bank on Amazon — last I checked, 4.6 stars from over 80,000 reviews. The common complaints are exactly what I found: slow recharge, no USB-C, basic LED indicator.

The Anker 737 sits at 4.5 stars from around 18,000 reviews. The recurring complaints are weight (it really is dense — 22.8 oz on my kitchen scale) and the occasional firmware quirk where the LCD lies about remaining capacity until you cycle it once.

When a Power Bank Isn't Enough

Look, I have to say this: if your honest use case is two days off-grid or running a CPAP or charging a drone, neither of these power banks is the right answer. You want a small power station.

The one I keep recommending to friends is the Anker SOLIX C300 DC Power Bank Station. It's 288Wh — roughly three times the capacity of the Anker 737 — with a LiFePO4 battery that'll outlast both power banks above. At around $150, it's barely more than the 737 and gives you AC-equivalent juice in a still-portable package. Check Price on Amazon.

If you want the version with an included wall charger and a small solar panel for camping, the Anker Solar Generator SOLIX C300 with 60W Solar Panel is what I'd buy. I used it on a 4-day trip to Joshua Tree in April and never ran out of juice.

For home backup — actually keeping your fridge running through an outage — you're looking at the Anker SOLIX C1000 Gen 2 Portable Power Station, which fully recharges in 49 minutes and runs a 2,000W load. That's a different category entirely from the 26800 and the 737.

Pros and Cons

Anker PowerCore 26800

Pros

• Cheapest reliable 26,800mAh on the market
• Charges 3 phones simultaneously without bog-down
• Light for its capacity (482g)
• Bulletproof firmware — there is no firmware

• Micro-USB recharge takes 6.5 hours
• No USB-C output at all
• Cannot charge laptops in any useful way
• LED indicator is imprecise — 4 dots tells you almost nothing

Anker 737 Power Bank

Pros

• 140W USB-C output charges laptops at full speed
• Recharges itself in 58 minutes
• Smart LCD shows actual watts in/out
• 24,000mAh is plenty for multi-device travel

• $129 is a lot for a power bank
• Heavy at 646g — you feel it in a jacket pocket
• Gets warm under 140W draw (not unsafe, but noticeable)
• Cosmetic shell isn't as durable as it looks

Which Should You Buy?

Buy the PowerCore 26800 if: You charge phones and tablets, you're on a budget, you don't mind a slow overnight recharge, and you'd rather throw a spare battery in a drawer for emergencies than carry one daily.

Buy the Anker 737 if: You own a USB-C laptop, you travel for work, you use a Steam Deck or a Switch on the go, and the digital display sounds useful to you (it is).

Buy a SOLIX C300 instead if: Your real use case is camping, van life, power outages, or anything where you need AC output or 200Wh+ of capacity.

Final Verdict

For the best anker power bank in 2026, the Anker 737 wins on every dimension that matters except raw dollar value. It's the one I keep in my daily backpack now, and the PowerCore 26800 has been demoted to the kitchen drawer where it lives next to a tangled Micro-USB cable, waiting to save someone whose phone died at dinner.

If the price gap stings, watch for Prime Day — the 737 has hit $99 twice in the last 12 months. At that price, there's no contest.

Q: Is the Anker 737 allowed on planes? A: Yes. At 86.4Wh it's well under the FAA's 100Wh limit for carry-on lithium batteries. I've flown with it through SFO, LAX, and JFK without TSA stopping me. Always carry it in your carry-on, never checked baggage.

Q: What is the actual powercore 26800 capacity? A: 26,800mAh at 3.7V, which works out to 96.48Wh of stored energy. That's roughly 5-6 full smartphone charges in real-world use, accounting for conversion losses.

Q: How long does the Anker 737 take to recharge? A: 58 minutes using a 140W USB-C PD charger. With a slower 65W charger it took me about 2 hours and 10 minutes. The included cable supports the full 140W; many third-party USB-C cables will not.

Q: Does the PowerCore 26800 support pass-through charging? A: No. You can't reliably charge the battery and a device through it at the same time. The 737 does support pass-through, which is another point in its favor for travel.

Q: Which is better for long camping trips? A: Honestly, neither. For camping more than 2 days, get a power station like the SOLIX C300. A power bank caps out around 100Wh due to flight regulations; a power station can carry 3-20x that.

Q: Are there cheaper alternatives to the Anker 737? A: Some no-name 100W power banks exist on Amazon for $60-80, but I've tested two and neither hit their rated output sustained. For 140W with a real display and pass-through, the 737 is currently the cheapest legitimate option.
