<\/a>Xtrem Instant Custom Case with integrated E-Ink display<\/p>\n

Xtrem Instant Custom Case: This E-Ink display for smartphones shows color images without a constant power supply and lets you easily share designs between compatible cases.<\/p>\n

The Xtrem Instant Custom Case is a protective smartphone case featuring an integrated display. At its core is a round 4-inch E-Ink panel with a pixel density of 212 PPI that supports four colors. This technology is particularly well-suited for the use case, as E-Ink displays only consume power when updating content and require no energy to maintain a static image. <\/p>\n

As a result, the case does not need a built-in battery; instead, it is powered via NFC. Images can be customized through a companion app, and content can even be transferred between two cases simply by placing them together. <\/p>\n

According to the manufacturer, the case does not interfere with the smartphone\u2019s NFC functionality, meaning contactless payments remain fully operational. MagSafe compatibility is also preserved. Beyond its display capabilities, the case is designed to offer robust protection and is rated to withstand drops from heights of up to 20 feet. It also includes a dedicated button for camera control. <\/p>\n

The Xtrem Instant Custom Case is available directly from the manufacturer for $74 for the iPhone 17 Pro Max<\/a> (on Amazon<\/a>). Additional versions are offered for other models, including the iPhone 17 (Pro), iPhone 16 (Pro\/Pro Max), and the iPhone 15 series.<\/p>\n

I have been active as a journalist for over 10 years, most of it in the field of technology. I worked for Tom\u2019s Hardware and ComputerBase, among others, and have been working for Notebookcheck since 2017. My current focus is particularly on mini PCs and single-board computers such as the Raspberry Pi \u2013 so in other words, compact systems with a lot of potential. In addition, I have a soft spot for all kinds of wearables, especially smartwatches. My main profession is as a laboratory engineer, which is why neither scientific contexts nor the interpretation of complex measurements are foreign to me.<\/p>\n","protected":false},"excerpt":{"rendered":"\u24d8 Xtrem Xtrem Instant Custom Case with integrated E-Ink display Xtrem Instant Custom Case: This E-Ink display for…\n","protected":false},"author":2,"featured_media":591573,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","_share_on_mastodon":"0"},"categories":[257],"tags":[1820,3735,88891,18,1821,19,431,17,1815,279,1819,1814,1822,140159,1818,1142,1143,82,1817,1816,250692],"class_list":["post-591572","post","type-post","status-publish","format-standard","has-post-thumbnail","category-mobile","tag-benchmarks","tag-case","tag-e-ink","tag-eire","tag-graphics-card","tag-ie","tag-iphone","tag-ireland","tag-laptop","tag-mobile","tag-netbook","tag-notebook","tag-processor","tag-protective-case","tag-reports","tag-review","tag-reviews","tag-technology","tag-test","tag-tests","tag-xtrem-instant-custom-case"],"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@ie\/116939211368754227","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/591572","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/comments?post=591572"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/posts\/591572\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media\/591573"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/media?parent=591572"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/categories?post=591572"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ie\/wp-json\/wp\/v2\/tags?post=591572"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
