The famous Anker 737 power bank is cheaper in the Czech Republic! It has a display, 24,000 mAh, and can charge up to 140W

Everyone has phone power banks at home. But what if you need to charge a laptop? Anker 737 GaNPrime is one of those rare pieces that can handle that too – and now it’s on sale, which is worth noting.

140 watts for laptop and phone

A capacity of 24,000 mAh and power of up to 140W via USB-C with Power Delivery. These are the parameters that make the Anker 737 more of a portable charging station than a regular power bank. You can charge a phone about four times, and it will keep a MacBook Pro 14″ running for approximately 6 hours straight.

You have 2× USB-C and 1× USB-A available, so you can charge three devices simultaneously. The display shows current power, remaining capacity, temperature, and estimated time to full charge – no guessing based on blinking LEDs.

And what about recharging the power bank itself? With a sufficiently powerful adapter (100W+), you can charge it from zero to a hundred in less than an hour. You’ll appreciate this when you remember in the evening that you’re leaving for a trip in the morning.

What 43 customers say

On Alza, the power bank has a rating of 4.6 out of 5 from 43 reviewers, over a thousand units have been sold, and the return rate is only 1.84%. Customers praise the build quality, informative display, and charging speed. “Best laptop charger, small, fast with large capacity,” summarizes one reviewer.

However, there are also reservations. One user reported problems with the full 140W output – the power bank occasionally switched to lower voltage. Another complains that his 66W phone only receives 17W. This is because Anker uses standard USB Power Delivery, not proprietary protocols like Huawei SuperCharge or OnePlus VOOC. If your phone does not support PD, you will not utilize the full power.

The package includes a 140W USB-C cable and a protective case. The weight of 635g is not negligible, but for 24,000 mAh with such power, it is standard.

The original price was 3,990 CZK, you can currently get it for 2,379 CZK. That’s a 40% discount, and for a power bank that can charge a laptop and recharges itself in an hour, it’s an excellent price. Anker has a long-standing good reputation in this category – and this is one of the reasons why.

Do you only use a power bank for your phone, or do you also need to charge a laptop?
