Cygnett ChargeUP Pro 25K 25,000Mah power bank – the power to spare (off-grid review)

Cygnett ChargeUP Pro 25K 25,000Mah/92.5Wh power bank has enough power to charge a 100W laptop – MacBook Pro or Windows 11.

To put it in perspective, 100W is at the high end of USB-C charging. 25,000mAh means enough to provide 25A of power for an hour. If your smartphone has a 5000mAh battery (5A), you could get up to five full charges. A laptop with a 45/60Wh battery would get 2/1.5 charges.

But wait, there is more. It has three output ports to share up to 118W.

It is precisely what a traveller needs.

We use Fail (below expectations), Pass (meets expectations) and Exceed (surpasses expectations or is the class leader) against many of the items below. We occasionally give a Pass ‘+’ rating to show it is good but does not quite make it to Exceed. You can click on most images for an enlargement.

First Impression – heavy like a pound of butter – Pass+

It is pretty big as far as power banks go at 80 (W) x 180 (H) x 26.5mm (D) x 499g – it has to store more than most.

It is a typical black box with a discrete digital display showing the remaining battery percentage.

Ports – Pass

USB-C #1 – the one you use to charge the bank. It can charge from as low as 5V/3A/15W to as high as 65W, so it is an ideal companion for Cygnett PowerMaxx 70W GAN dual-port wall charger – power for most laptops.

• USB-C #1 then becomes an output port capable of delivering 5V/3A/15W), 9V/3A/27W, 12V/3A/36.0W, 15V/3A/45W, and 20V/5A/100W (if you use a 5W rated cable else it stops at 60W.
• USB-C #2 is a standard PD port – 5V/3A/15W, 9V/2A/18W) and 12V/1.5A/18W.
• USB-A #3 has the same 18W rating as #2.

It includes a 3W USB-C to USB-C cable, but you must buy a 5W cable to get 100W.

Tests

• Surface Pro 8 60W (45Wh battery) took 1.5 hours and used 50% of the power bank.
• Samsung Galaxy S22 Ultra 5000W took 1 hour and used 20%
• Charge 0-100% Cygnett 70W GaN Charger 1 hour and 58 minutes
• Charge 0-100% 5V/3A/15W – over six hours

What it is not

• It does not support PPS variable rate charging. That is not an issue except where the device to be charged expects PPS for fast charging.
• It does not work as a Pass-through (UPS) charger.
• It will work with MagSafe cables, but there is no negotiation between the charge and the host.
• The readout shows the percentage left. Some brands offer more detailed specs.

CyberShack’s view – Cygnett ChargeUP Pro 25K 25,000Mah power bank is a good basic power bank

It keeps the price low by being a big power bank with no frills. You could easily spend twice that to get more ports and more detailed use statistics. And remember that you need a 65W Gan Charger to fill it.

Rating Explanation

• Features: 80 – it’s a basic three-port PD power bank
• Value: 90 – you could spend a lot more to get more features
• Performance: 90 – it meets or exceeds our expectations for charge speed and stable volt/amps
• Ease of Use: 85 – it should have come with a 5W cable
• Design – 80 – a bland black rectangle with LCD readout – but that is how you keep costs under control
