The best-selling power bank in the Czech Republic is on sale! It has 30,000 mAh and supports 65W charging

FIXED Zen2 30 Plus dominates the Czech power bank market. According to Heureka, it is the absolute number one in sales. Moreover, its price dropped from the original 1799 to 1246 CZK. For that price, you get 30,000 mAh, 65W power, and an LCD display. It sounds like a great deal, but there’s a catch – it weighs almost 600 grams.

30,000 mAh capacity

A capacity of 30,000 mAh sounds amazing, but beware of the math. The power bank has a voltage of 3.7V, while a phone charges at 5V. After recalculation and conversion losses, the real usable capacity is around 20,000 mAh.

What does that mean in practice?

• iPhone 15 (3349 mAh) – 5-6 charges
• Samsung S24 Ultra (5000 mAh) – 3-4 charges
• Xiaomi 14T Pro (5000 mAh) – 3-4 charges
• iPad Air (8600 mAh) – 2 charges

For a vacation without an outlet, it’s more than enough. For a month-long trek in the Himalayas, maybe not.

65W power: can even charge a laptop (theoretically)

The USB-C port supports 65W Power Delivery 3.0. This is sufficient for charging most ultrabooks – MacBook Air, Dell XPS 13, ThinkPad X1 Carbon. You won’t charge gaming laptops with 100W+ adapters, but you’ll at least slow down the discharge.

The USB-A ports each deliver a maximum of 22.5W – solid for phones, but no miracle. When charging three devices simultaneously, the power is split to a total of 20W.

LCD display: finally you can see how much is left

A simple LCD display shows the remaining capacity in percentages. No science fiction, but useful. You don’t have to guess if you have enough juice to charge your phone.

Some power banks only have LEDs – 4 lit = full, 1 blinking = almost empty. LCD is more accurate but consumes more power. However, with 30,000 mAh, this doesn’t play a role.

597 grams: a brick in your backpack

The biggest problem with Zen2 30 Plus is its weight. Almost 600 grams is like two cans of beer or three phones. You’ll notice it in your backpack.

For 1246 CZK, the FIXED Zen2 30 Plus is a solid purchase. It’s not a technological marvel, but it delivers what it promises – it charges everything and lasts a long time. Just clarify if you really need to carry an extra half a kilo. Sometimes a smaller power bank that you actually carry is more useful than a giant one that stays at home.
