ampow.com website review

17 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.6 s.

A phone's processor spends 9.2 s on main-thread work while loading, 2.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 7,628 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Shopify, salesmartly.com and Facebook and others), adding 3.4 MB and 1.2 s of main-thread time.

15 images could be 730 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 750 ms faster on a phone.

About 919 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

Your mobile performance score is 52. Pages that score under 90 lose visitors before the first paint.

Shopify costs a phone 650 ms of main-thread work and 1.9 MB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

26 files are served with short cache lifetimes, so returning visitors download them again (306 KiB).

salesmartly.com costs a phone 213 ms of main-thread work and 366 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

azurefd.net costs a phone 11 ms of main-thread work and 443 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 167 KiB of CSS is downloaded but never applied on this page.

13 long tasks block the main thread while loading, the longest for 143 ms. During a long task the page ignores taps.

Polyfills for old browsers add 30 KiB JavaScript that modern phones do not need.

22 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

5 KiB JavaScript is shipped twice across bundles.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Your largest element takes 9.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 30.5 s. Good is under 3.8 s.

Visually, the page fills in at 10.5 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 169 ms to 212 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.8 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 392 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.8 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.1 MB in 417 requests on a phone: scripts 2.4 MB (194), images 1.8 MB (33) and other files 1.4 MB (136). Under 2 MB keeps phones on slow connections fast.

c8577a1df210126991a8c79837c61c3f_7e181d95-2995-4985-88f1-0c5 is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

1 image is downloaded at several times the size a phone draws it, for example OVONIC_X2_Pro.png at 1,426 px wide, shown at 360 px. Resized copies would save about 64 KiB.

1 image further down the page (151 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.74 g of CO₂e: 209.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Your title is 78 characters, so Google will cut it off around 60: “Ovonic EU | High C-Rate LiPo Batteries & Smart Charger for Enthusiasts – Ampow”.

There are 2 <h1> headlines (“” and “”). One clear main headline is easier for people and search engines.

The homepage links to 300 pages on ampow.com and 20 external pages.

https://www.ampow.com/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://www.ampow.com/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://www.ampow.com/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

Your longest form asks for 27 fields (0 required). Every extra field lowers completion.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.
