Best Alternatives to Anker 737 Power Bank: High-Capacity Chargers Worth Considering

The Anker 737 Power Bank is a popular choice for users who need a portable charger capable of powering more than just a phone. Its appeal comes from high-capacity charging, support for laptops and tablets, and a design aimed at people who need serious portable power.

But it is not the only option.

If you are looking for Anker 737 alternatives, there are several other high-capacity power banks that can suit different needs, whether you want something more compact, more affordable, better for travel, or focused primarily on laptop charging.

This guide looks at some of the best power banks like Anker 737, what to compare before buying, and which features matter most when choosing a high-capacity portable charger.

What to Look for in an Anker 737 Alternative

Before comparing specific models, it helps to understand what makes a good alternative.

The Anker 737 sits in the premium high-output power bank category, so a comparable option should ideally offer some combination of:

• High-capacity battery storage
• USB-C Power Delivery
• Laptop charging support
• Multiple charging ports
• Fast recharge times
• Travel-friendly design
• Clear battery information
• Strong build quality

Not every alternative needs to match every feature. Some users may care more about portability, while others may prioritize total output or charging multiple devices at once.

1. Baseus Blade Series Power Bank

The Baseus Blade series is one of the most relevant Anker power bank alternatives for people who want to charge laptops and mobile devices while traveling or working remotely.

Its slim design makes it noticeably different from the more traditional block-style power bank shape.

Why consider it

The Blade series is appealing because it is designed around USB-C charging and high-output use cases.

It can work well for:

• Laptops
• Tablets
• Smartphones
• Wireless earbuds
• Portable gaming devices

The flatter design can also make it easier to carry in a laptop bag.

Its larger USB-C power banks are especially relevant for users searching for laptop charger alternatives.

They can be especially practical for:

• MacBook users

3. INIU High-Capacity Power Bank

INIU offers several portable chargers that may appeal to buyers who want a lower-cost alternative to premium power banks.

Its larger USB-C power banks may be worth considering for buyers who value simplicity and broad compatibility.

• Other travel electronics

Best for

Anker 737 Alternatives for Laptop Charging

If laptop charging is your main priority, focus on USB-C Power Delivery output.

A power bank can have a large battery capacity but still charge a laptop slowly if its output is limited.

Before buying, check:

• Maximum USB-C output
• Whether the laptop supports USB-C charging
• Laptop wattage requirements
• Whether full charging speed is supported
• Total output when multiple devices are connected

For demanding laptops, a higher-output power bank is usually more suitable.

UGREEN, Zendure, Baseus, and some Sharge models are especially relevant in this category.

Best Alternatives for Travel

Travel users should think about more than power output.

Weight and size matter just as much.

A very large power bank may provide excellent capacity but become inconvenient to carry every day.

Look for:

• Compact dimensions
• Reasonable weight
• USB-C charging
• Multiple ports
• Clear battery display
• Airline-friendly capacity where applicable

The Baseus Blade style can be attractive because its flatter shape fits well inside laptop bags.

Best Alternatives for Phones and Tablets

If you do not actually need laptop charging, you may not need a direct Anker 737 equivalent.

A smaller power bank can be cheaper, lighter, and easier to carry.

For smartphone and tablet use, consider:

• 10,000 mAh to 20,000 mAh capacity
• USB-C fast charging
• Two or more output ports
• Compact dimensions

INIU and Belkin can be worth considering for this type of use.

High-Capacity Power Bank Alternatives: Capacity vs Portability

One of the biggest trade-offs in this category is battery size.

Higher capacity generally means more charging time away from an outlet, but it also means:

• More weight
• Larger dimensions
• Longer recharge times
• Less pocket-friendly portability

If you travel frequently, the biggest power bank is not always the best option.

A slightly smaller charger that you actually carry every day may be more useful than a huge battery that stays at home.

Display and Battery Information

One feature that has become more common in premium power banks is a digital display.

A basic display may show battery percentage.

More advanced models can show:

• Charging wattage
• Estimated remaining time
• Input power
• Output power
• Individual port activity

This is not essential, but it can be helpful for users who regularly charge laptops and other high-power devices.

Sharge and some UGREEN or EcoFlow models can be particularly interesting for buyers who value detailed charging information.

Number of Ports

Think about how many devices you usually charge at once.

A power bank with only one USB-C port may be enough for a phone, but users carrying a laptop, phone, tablet, and earbuds may benefit from multiple ports.

A good travel setup may include:

• Two USB-C ports
• One USB-A port

This gives you flexibility without carrying several separate power banks.

However, remember that the maximum output may be shared when several devices are connected.

Charging Speed Matters

Fast charging is one of the main reasons people consider premium power banks.

But charging speed depends on both the charger and the device.

A phone that only accepts lower wattage will not charge faster simply because the power bank supports very high output.

The same applies to laptops.

When comparing Anker 737 alternatives, match the power bank to your actual devices rather than choosing based only on the largest wattage number.

Which Anker 737 Alternative Is Best for You?

Different users need different things.

Choose Baseus if:

You want a flatter power bank that works well in a laptop bag.

Choose UGREEN if:

You regularly charge several high-power USB-C devices.

Choose INIU if:

You want a more affordable high-capacity charger.

Choose Zendure if:

You need portable power for serious work or travel.

Choose Sharge if:

You care about design and detailed charging information.

Choose Belkin if:

You want a straightforward charger for everyday devices.

Choose EcoFlow if:

You want a high-output charging product from a company focused heavily on portable power.

Is It Worth Choosing an Alternative to the Anker 737?

Yes, especially if your priorities differ from what the Anker 737 is designed to offer.

You may prefer an alternative because you want:

• A slimmer design
• Lower price
• More ports
• Different charging output
• Better portability
• A different display
• Simpler controls

The Anker 737 remains relevant for high-output portable charging, but there is no reason every user needs the same type of power bank.

Final Thoughts

The best Anker 737 alternatives depend on what you actually need to charge.

For laptops and demanding devices, focus on high USB-C output and strong multi-device performance. For travel, weight and shape may matter more. For smartphones and tablets, a smaller and less expensive option may be more practical.

Products from Baseus, UGREEN, INIU, Zendure, Sharge, Belkin, and EcoFlow all represent different approaches to portable charging.

Before buying, compare the exact model specifications with your laptop, phone, tablet, and other devices. Capacity, charging output, number of ports, portability, and device compatibility are the most important factors.

The best alternative is not necessarily the model with the biggest battery or highest advertised wattage. It is the one that fits your daily charging routine without adding unnecessary size or cost.
