The gigantic 69,000mAh power bank is on sale again. It hasn't been this cheap since December

Most power banks will charge your phone. This one can also power appliances that plug into a car socket and charge from a solar panel. The ChoeTech with a gigantic capacity of 69600mAh now costs 3,509 CZK with code ALZADNY35, dropping to its December low. The regular catalog price is 5,399 CZK.

Quick summary:
✅ Makes sense if you go on multi-day trips, camp, or have a caravan and need a power supply for appliances, not just your phone.
⚠️ Consider that due to its capacity over 250 Wh, it is not allowed on airplanes and weighs around 1.6 to 2 kg.
💡 For 3,509 CZK, you get the features of a small power station – but the discount compared to the previous price is rather symbolic (270 CZK).

Why this power bank is interesting

This ChoeTech power bank deviates from typical pocket models in its concept – it’s more like a small power station in the form of a power bank. In addition to USB ports, it has a 12V car socket, can be charged from a solar panel, and supports 10W Qi wireless charging. It also adds an LED flashlight with SOS mode and IP65 protection, clearly targeting campsites, caravans, and situations without an outlet. For 3,509 CZK with code ALZADNY35, it’s an affordable way to have power even where a regular power bank isn’t enough.

Key parameters in plain language

At its heart is a capacity of 69,600 mAh, which is roughly over 250 Wh of energy – many times more than typical 20,000mAh models. The output power is 60 W via USB-C PD, so you can even charge a laptop that requires, for example, 45 W (one review confirms this). It features 2× USB-C, 1× USB-A, a DC port, and a cigarette lighter socket, allowing for charging of up to five devices simultaneously. Good news at the end: unlike many competitors, a reviewer explicitly states that the advertised capacity is indeed real.

Practical aspects: weight, airplane, charging

The enormous capacity comes with a weight penalty: the power bank weighs around 1.6 to 2 kg (the manufacturer states 2 kg, users measure closer to 1.6 kg). Despite its capacity, reviews indicate it is pleasantly compact, and a neoprene case is often included in the package. A crucial practical note for travelers: due to its energy exceeding 250 Wh, you cannot take this power bank on an airplane – the limit for both carry-on and checked baggage is 100 Wh, exceptionally 160 Wh with approval. Ideal for a car trip or caravan, but not for air travel.

It charges via USB-C, a DC charger, or a solar panel, with one user appreciating that the solar panel works even in weaker light and the power bank “doesn’t give up.” However, expect that charging such a large battery takes a while – several reviews mention slower charging, which makes sense for a capacity over 250 Wh. A minor drawback is the absence of a numerical display; only LED indicators show the status.

What users say

The rating is high – 4.7 out of 5 and 89% recommendation – but it’s fair to add that it’s based on only 9 ratings and 4 reviews, so it’s a small sample from which strong conclusions about long-term reliability cannot be drawn. Those who wrote reviews mainly praise the huge and real capacity, versatility of outputs, and robust construction. One user describes that thanks to the 12V socket, it can even power a diesel heater for a caravan.

However, it’s fair to mention the downside. Alza states a high return rate of 8.68% for the product, and for one reviewer, the first unit immediately stopped working (couldn’t be charged or turned on) – but the warranty claim was processed overnight, and the second unit worked. With such capacity and price, it’s advisable to check functionality immediately after unboxing and not rely on every unit being flawless.

When it doesn’t make sense

If you want a power bank for your pocket or daily carry, this isn’t it – you won’t comfortably tuck away 1.6 to 2 kg anywhere, and it’s an unnecessarily large cannon just for charging a phone. Those who fly frequently will hit a hard ceiling: this power bank cannot be taken on an airplane. And if you’re mainly looking for a big discount, keep in mind that the current promotion only shaves off 270 CZK compared to the previous price – the value here comes from the features, not the discount amount.

Verdict: who it’s worth it for

If you go on multi-day trips, camp, or need power for your caravan, the ChoeTech 69600mAh PD60W for 3,509 CZK is a very versatile piece – the car socket, solar input, and wireless charging make it more of a small power station than a power bank. However, take seriously that it is not allowed on airplanes, that it weighs around two kilograms, and that the high return rate dictates checking its functionality immediately upon delivery. For off-grid use, it’s a justifiable choice at this price; those looking for a lightweight power bank for everyday carry will be happier with a smaller and cheaper model.

Would you take a large power bank for camping and in the car, even at the cost of it not being allowed on an airplane?
